1. Introduction & Taxonomy

Heliconia rostrata, universally known as the Lobster Claw or Hanging Heliconia, stands as one of the most architecturally spectacular members of the Heliconiaceae family. First formally described by German botanist Heinrich Wilhelm Schott in 1827 from specimens collected in Peru's Amazonian lowlands, this species ranges naturally from southern Peru through Ecuador and into western Colombia, thriving in humid tropical forests at elevations between 200 and 1,400 meters. The plant's common name derives from its extraordinary pendent inflorescence—a cascading chain of brilliant red bracts tipped with yellow and green margins that bear an uncanny resemblance to the segmented claws of a freshly cooked lobster.

Unlike most Heliconia species that hold their inflorescences erect or horizontally, H. rostrata's flower structure hangs downward in a graceful arc that can extend 45 to 60 centimeters in length, with 15 to 35 individual boat-shaped bracts arranged in a zigzag pattern along the pendulous rachis. This distinctive pendant habit evolved specifically to accommodate the feeding behavior of long-billed hermit hummingbirds (particularly Phaethornis species), which hover beneath the bracts to access the nectar-rich tubular flowers hidden within each crimson keel. The year-round flowering habit mentioned in historical accounts has made this species invaluable to indigenous Amazonian communities, who have long observed its blooms as a reliable indicator of forest health and hummingbird populations.

Since its introduction to Western horticulture in the late 1960s through botanical expeditions conducted by the Missouri Botanical Garden, Heliconia rostrata has become the flagship species of tropical floriculture, commanding premium prices in the cut flower industry and serving as the iconic centerpiece of tropical gardens worldwide. Its striking visual impact led to widespread cultivation in Hawaii by the 1980s, where it became a cornerstone of the state's multimillion-dollar tropical flower export industry, and subsequently spread to commercial production facilities in Costa Rica, Ecuador, and Southeast Asia.

One of the best-known and most popular species, the Lobster Claw has a large, dense, pendent inflorescence with bright red, parrot beak-like bracts (similar in appearance to lobster claws) rimmed with yellow, and flowering all year round.

2. Biology & Morphology

Growth Form & Architecture

Heliconia rostrata is a large, musoid (banana-like) herbaceous perennial that grows from a robust underground rhizome. Like its close relatives the bananas (Musaceae), it forms pseudostems from tightly rolled leaf sheaths. Each pseudostem produces a single inflorescence before dying back, while new shoots continuously emerge from the rhizome to replace it. The large, paddle-shaped leaves are arranged in a single plane (distichous), giving the plant its characteristic banana-like silhouette.

Leaf Morphology

The leaves of Heliconia rostrata are large and paddle-shaped, arranged in two ranks (distichous) along the pseudostem. Unlike bananas, heliconia leaves typically have long petioles that twist at the base, orienting the blade in a characteristic pattern. The midrib is prominent, and leaves can range from 30 cm to over 3 m long depending on species.

Inflorescence & Bract Structure

The spectacular "flowers" of heliconias are actually colourful, waxy bracts — modified leaves that enclose the small, tubular true flowers within. These bracts can be erect (pointing upward), pendant (hanging downward), or spiralling, and come in vivid reds, oranges, yellows, pinks, and greens. The true flowers emerge one at a time from within each bract and produce nectar that attracts hummingbird pollinators — heliconias and hummingbirds have co-evolved in a remarkable mutualistic relationship.

Key Characteristics

• Height: 1-5m
• Growth Habit: Musoid / Rhizomatous
• Growth Rate: Fast under optimal conditions

Notable Adaptations

Heliconia rostrata produces robust pseudostems that reach 1.5 to 3 meters in height, formed by the tightly wrapped bases of 8 to 12 elongated leaves. Each leaf blade measures 80 to 150 centimeters in length and 25 to 35 centimeters in width, with a prominent central midrib and parallel venation typical of monocots. The leaves emerge in a distichous (two-ranked) arrangement from a thick, horizontal rhizome system that can extend 40 to 60 centimeters underground and produce daughter shoots at intervals of 15 to 25 centimeters along its length. The rhizomes themselves measure 3 to 6 centimeters in diameter and store substantial carbohydrate reserves in the form of starch granules, enabling the plant to regenerate rapidly after damage or seasonal stress.

The pendant inflorescence emerges from the center of the pseudostem on a sturdy peduncle 60 to 90 centimeters long, which curves downward under the weight of the developing bracts. Each waxy bract measures 10 to 15 centimeters in length and forms a distinctive boat-shaped keel with a pronounced rostrate (beaked) tip—the feature that inspired Schott's specific epithet. The bracts graduate in size from largest at the base to smaller toward the tip, creating a tapered silhouette. Inside each bract nestle 5 to 10 true flowers, which are small (2 to 3 centimeters), tubular, and greenish-white with yellow tips. These flowers produce copious nectar with a sucrose concentration of 18 to 24 percent, optimized to attract hermit hummingbirds such as Phaethornis longirostris, P. guy, and P. superciliosus.

The pollination syndrome is highly specialized: hermit hummingbirds establish trapline routes visiting H. rostrata plants in sequence, hovering beneath each bract to probe the flowers with bills measuring 35 to 45 millimeters in length. As the birds feed, pollen accumulates on their crown feathers from the exserted stamens, achieving cross-pollination when they visit subsequent inflorescences. Following successful pollination, each flower develops into a small blue-purple drupe 8 to 12 millimeters in diameter containing 1 to 3 hard seeds, which are dispersed by birds including tanagers, manakins, and cotingas that consume the lipid-rich fruit pulp.

3. Reproduction & Propagation

The primary propagation methods for Heliconia rostrata: Rhizome division or seed.

Propagating Heliconia rostrata

Seed propagation of Heliconia rostrata requires fresh seed, as viability declines rapidly—falling to less than 30 percent germination after 60 days of storage even under ideal conditions. Fresh seeds should be cleaned of all fruit pulp (which contains germination inhibitors) by soaking in water for 24 hours, then mechanically scarified by carefully nicking the hard seed coat with a file or blade opposite the embryo. Treated seeds germinate best at constant temperatures of 26 to 30°C with high humidity (85 to 95 percent relative humidity) in a well-drained medium of 2 parts peat, 1 part perlite, and 1 part coarse sand. Germination is erratic and slow, typically requiring 45 to 120 days for the first shoots to emerge. Seedlings grow slowly in their first year, producing only 3 to 5 leaves, and typically require 2.5 to 4 years to reach flowering maturity—making seed propagation impractical for commercial production.

Vegetative propagation through rhizome division is the preferred method for both commercial growers and home gardeners. The optimal time for division is at the onset of the wet season (March to May in the Northern Hemisphere tropics), when plants are actively initiating new growth. Select mature clumps at least 3 years old with multiple pseudostems. Using a sharp spade or machete, excavate around the clump and lift the entire rhizome mass. Divisions should include at least 2 to 3 pseudostems (or emerging shoots) with 15 to 20 centimeters of rhizome and an intact root system. Cut surfaces should be dusted with sulfur or cinnamon powder to prevent fungal infection. Replant divisions immediately at the same depth they were growing previously, water thoroughly, and maintain consistently moist soil for the first 4 to 6 weeks until new root growth is established.

Divisions typically resume growth within 2 to 3 weeks and produce their first inflorescence 6 to 12 months after transplanting, depending on growing conditions. To maximize division success, avoid disturbing plants during the dry season or when they are actively flowering. Commercial producers often practice serial division, removing 2 to 3 peripheral shoots from mature clumps every 6 months without disturbing the central mother plant, maintaining continuous flower production while generating propagation stock.

Heliconia seeds have a hard, stony endocarp and can be slow to germinate — typically 2-6 months, sometimes up to a year. Soak seeds in warm water for 48-72 hours before sowing, and scarify if possible. Maintain warmth (28-32°C) and consistent moisture. Rhizome division is much faster and more reliable for established plants.

Vegetative Propagation

• Rhizome Division: The most reliable method for heliconias. Divide established clumps at the start of the growing season, ensuring each division has at least 2-3 pseudostems and a section of rhizome with healthy roots
• Timing: Best done in early spring (or start of wet season in the tropics) just as new growth begins

4. Cultivation Requirements

Heliconia rostrata thrives in rich, moisture-retentive but well-drained soils with pH between 5.5 and 6.8—slightly acidic conditions that optimize nutrient availability in tropical systems. Incorporate 8 to 12 kilograms of well-aged compost or composted manure per square meter before planting, along with 150 to 200 grams of slow-release balanced fertilizer (14-14-14 NPK). Once established, feed monthly during the active growing season with a high-nitrogen formula (20-10-10) at 100 to 150 grams per clump, switching to a balanced formulation (15-15-15) when flower buds are visible to promote bract color intensity. Organic growers achieve excellent results with monthly applications of fish emulsion (5-1-1) diluted 1:10 or compost tea.

Water requirements are substantial: mature clumps transpire 15 to 25 liters per day during hot weather and require consistently moist (but not waterlogged) root zones. Drip irrigation delivering 3 to 5 liters per hour per plant, run for 2 to 4 hours daily depending on temperature and rainfall, provides ideal moisture levels. Mulch heavily with 8 to 12 centimeters of organic material (shredded bark, cocoa hulls, or leaf litter) to conserve moisture, suppress weeds, and maintain cool root temperatures. Light requirements are moderate: H. rostrata grows best with 40 to 60 percent shade (equivalent to 2,000 to 4,000 foot-candles or 21,500 to 43,000 lux), such as provided by high canopy trees or shade cloth. Full tropical sun bleaches the foliage and reduces flower quality, while excessive shade (below 30 percent full sun) results in weak, elongated growth and reduced flowering.

Space plants 1.5 to 2.5 meters apart in the landscape to allow for mature clump spread. Prune spent inflorescences at the base of the peduncle to maintain appearance and redirect energy to new growth. Remove yellowing or damaged leaves by cutting at the base of the petiole. Every 4 to 6 years, rejuvenate clumps by dividing and replanting, which restores vigor and flower production quality.

Soil / Substrate

Rich, well-draining soil with abundant organic matter. A mix of compost (40%), peat or coir (30%), perlite (20%), and bark (10%) works well. Heliconias are heavy feeders that thrive in fertile, humus-rich soil.

Watering

Maintain consistent moisture during active growth. Heliconias are tropical plants that prefer evenly moist soil and do not tolerate prolonged drought. Water deeply and regularly during the growing season, reducing frequency in cooler months.

Light Requirements

Most heliconias perform best in full sun to bright, filtered light. Some species (particularly Hedychium and Alpinia) tolerate full sun in humid climates, while forest-floor species prefer dappled shade. Strong afternoon sun in dry climates can scorch leaves.

Temperature

• Optimal Growth: 20–30°C (68–86°F)
• Minimum Tolerance: 2°C (36°F)
• USDA Hardiness: Zones 10-12

Humidity

Most heliconias thrive at 60–80% relative humidity. Low humidity causes brown leaf edges, reduced flowering, and increased pest susceptibility. In dry climates, mist foliage regularly, use humidifiers, or group plants together to create a favourable microclimate.

Fertilization

Heliconias are heavy feeders during active growth. Apply a balanced fertilizer (NPK 10-10-10 or 20-20-20) every 2–3 weeks during the growing season. Supplemental potassium promotes flowering, while nitrogen drives leafy growth. Organic mulch and compost provide slow-release nutrition. Reduce or stop feeding during dormancy or winter.

5. Diseases & Pests

Heliconia rostrata is susceptible to several fungal pathogens, most notably Heliconia rust caused by Puccinia heliconiae, which appears as orange-brown pustules on leaf undersides and can cause severe defoliation in humid conditions with poor air circulation. Control rust through preventive applications of copper-based fungicides (copper hydroxide at 1.5 to 2 grams per liter) every 14 days during rainy periods, or systemic triazole fungicides (propiconazole at 0.5 milliliters per liter) for severe infections. Maintain plant spacing to improve air movement and avoid overhead irrigation, which promotes spore germination. Leaf spot diseases caused by Bipolaris species and Curvularia species present as brown or black necrotic lesions with yellow halos; these respond to applications of chlorothalonil (2 grams per liter) or mancozeb (2.5 grams per liter) at 7 to 10-day intervals.

Bacterial wilt caused by Ralstonia solanacearum occasionally affects Heliconia plantings, particularly in poorly drained soils or where previous solanaceous crops were grown. Symptoms include sudden wilting of entire pseudostems despite adequate soil moisture, followed by collapse and yellowing. Infected plants should be removed and destroyed immediately, and the soil drenched with copper sulfate solution (3 grams per liter). Do not replant Heliconias in the same location for at least 2 years. Rhizome rot caused by Pythium species and Phytophthora species occurs in waterlogged conditions; prevent through proper drainage and avoid overwatering. Treat affected plants by reducing irrigation, improving drainage, and drenching with fosetyl-aluminum (2.5 grams per liter) or metalaxyl (1 gram per liter).

Common insect pests include the banana aphid (Pentalonia nigronervosa), which vectors viral diseases and should be controlled with insecticidal soap (30 milliliters per liter) or neem oil (5 milliliters per liter). Heliconia beetles (Xanthonia hispida and related species) feed on developing bracts and flowers, causing cosmetic damage; handpick adults or apply pyrethrin-based insecticides. The sugarcane weevil (Metamasius hemipterus) occasionally bores into rhizomes and pseudostem bases in commercial plantings; control through sanitation (removing dead plant material) and soil applications of imidacloprid granules (0.5 grams per plant) in severe infestations.

Major Diseases

Heliconia Rust (Puccinia heliconiae)

The most common fungal disease of heliconias. Causes reddish-brown pustules on leaf undersides, leading to yellowing and premature leaf drop. Remove affected leaves promptly and improve air circulation. Fungicides containing mancozeb or chlorothalonil can help prevent spread.

Rhizome Rot (Pythium, Fusarium)

Fungi attack the rhizome in waterlogged conditions, causing soft, mushy, discoloured tissue. Prevention: ensure excellent drainage, avoid overwatering, and sterilize tools. In containers, use well-draining media and never let pots sit in standing water.

Bacterial Wilt (Ralstonia solanacearum)

Causes rapid wilting and collapse of pseudostems with watersoaked, foul-smelling rhizome rot. There is no cure; remove and destroy infected plants immediately. Use disease-free planting material and avoid replanting in contaminated soil.

Common Pests

• Spider Mites — Thrive in dry conditions; cause stippled, bronzed foliage. Increase humidity and apply miticides.
• Shoot Borers — Larvae tunnel into pseudostems, causing wilting of individual shoots. Remove and destroy affected stems.
• Mealybugs — White, cottony masses in leaf sheaths and at the base of pseudostems. Treat with isopropyl alcohol or systemic insecticide.
• Scale Insects — Brown or white bumps on stems and leaf undersides. Scrape off manually or treat with horticultural oil.
• Rhizome Scale — Tiny scales on stored or dormant rhizomes. Inspect rhizomes before planting and treat with insecticidal soap.
• Slugs & Snails — Feed on tender new shoots emerging from rhizomes. Use barriers, traps, or baits.

6. Indoor Growing Guide

Growing Heliconia rostrata as an indoor or conservatory specimen presents challenges due to its substantial size and specific environmental requirements, but success is achievable in spaces with ceiling heights of at least 3.5 to 4 meters and access to abundant natural or supplemental lighting. Select the most compact clones available and plant in large containers of at least 150 to 200 liters capacity (such as half wine barrels or commercial 200-liter pots) filled with a rich, well-draining mix of 40 percent potting soil, 30 percent coconut coir, 20 percent perlite, and 10 percent worm castings. Drainage is critical—ensure containers have multiple large drain holes and never allow pots to sit in standing water.

Maintain indoor temperatures between 21 and 29°C year-round, with nighttime temperatures not falling below 18°C, as cold stress below 15°C causes leaf chlorosis and halts growth. Humidity is perhaps the most critical factor: H. rostrata requires 70 to 85 percent relative humidity, necessitating frequent misting (3 to 4 times daily), use of humidifiers, or placement on large gravel-filled humidity trays. Lighting should provide a minimum of 4,000 to 6,000 foot-candles (43,000 to 64,500 lux) for 12 to 14 hours daily; this typically requires supplemental LED grow lights (full-spectrum panels delivering 200 to 400 watts) even in bright south-facing conservatories. Rotate containers quarterly to ensure even growth, as plants naturally lean toward the strongest light source. With optimal conditions, containerized specimens will flower, though inflorescences may be somewhat smaller than field-grown plants (35 to 45 centimeters versus 50 to 60 centimeters). Be prepared to divide and repot every 2 to 3 years as rhizomes fill containers.

Container Selection

Use a wide container that allows the rhizome to spread horizontally. Heliconias produce vigorous lateral rhizome growth, so wider pots are better than deep narrow ones. Use containers at least 45-60 cm in diameter for mature plants. Ensure adequate drainage holes to prevent rhizome rot.

Indoor Light

Most heliconias need bright, indirect light for best growth and flowering indoors. A south- or west-facing window works well. Supplement with grow lights during winter — full-spectrum LEDs for 12-14 hours daily make a dramatic difference in growth quality and flower production. Many heliconias need very high light levels (10,000+ lux) to flower indoors.

Humidity & Air Circulation

Indoor humidity of 50-70% is adequate for most species; 70-80% is optimal for lush growth and flowering. Central heating and air conditioning can drop humidity below 30%, causing brown leaf edges, reduced growth, and pest vulnerability. Use humidifiers, group tropical plants together, or grow in a bathroom with natural light.

Seasonal Indoor Care

• Spring: Resume regular feeding and increase watering as new growth emerges. Repot or divide if rhizomes are crowded.
• Summer: Peak growth — water consistently, feed every 2 weeks, consider moving outdoors to a shaded spot for the summer months
• Autumn: Reduce feeding. Growth slows; reduce watering frequency.
• Winter: Minimal growth — water sparingly, stop fertilizing. Watch for spider mites in dry heated rooms.

7. Landscape Use & Design

In tropical and subtropical landscape design, Heliconia rostrata functions as a bold architectural specimen, most effectively deployed as a focal point where its pendant inflorescences can be viewed from below—on slopes, elevated planters, or alongside paths where visitors can appreciate the full sculptural drama of the hanging blooms. The plant's substantial form and year-round presence make it unsuitable for mixed perennial borders but ideal for tropical mass plantings where groups of 5 to 9 clumps create impactful drifts. Space individual clumps 2 to 2.5 meters apart to allow for mature spread while maintaining a cohesive visual mass.

Companion planting works best with lower-growing species that appreciate similar cultural conditions and provide contrasting foliage textures: Calathea species (C. makoyana, C. ornata) and Maranta leuconeura offer stunning patterned foliage at ground level, while Costus species (C. barbatus, C. woodsonii) contribute additional floral interest with their terminal cone-like inflorescences. Gingers in the genus Alpinia, particularly A. purpurata and A. zerumbet, share similar light and moisture requirements and bloom at complementary times. For vertical layering, underplant with shade-tolerant ferns such as Nephrolepis exaltata or Blechnum species. The bold form of H. rostrata contrasts beautifully with fine-textured plants like bamboos (Bambusa textilis or Otatea acuminata) planted as a backdrop. In contemporary tropical gardens, pair with equally architectural foliage plants like Alocasia species, Colocasia 'Black Magic', or the giant bird of paradise (Strelitzia nicolai) for a lush, jungle aesthetic. The brilliant red bracts coordinate especially well with hot-colored schemes featuring Canna cultivars, Croton varieties with red tones, and red-variegated Cordyline fruticosa selections.

Design Applications

• Tropical Border: Combine with bananas, gingers, aroids, and tree ferns for layered jungle texture
• Focal Point: Heliconias command attention — use as bold architectural specimens in garden beds or along paths where the inflorescences can be admired up close
• Partial Shade: Most heliconias thrive in dappled shade or filtered light, perfect for underplanting beneath palms or large trees
• Container Feature: Large decorative pots on patios and terraces allow flexible placement and easy winter protection
• Cut Flowers: Heliconia inflorescences are among the most spectacular and long-lasting tropical cut flowers, prized worldwide in floristry

Companion Planting

Create stunning tropical compositions by pairing with:

• Banana species (Musa, Ensete) — dramatic height and complementary bold foliage
• Heliconias — bold, colourful inflorescences and similar cultural needs
• Tree Ferns (Dicksonia, Cyathea) — structural understory contrast
• Aroids (Alocasia, Colocasia) — bold foliage at the middle and lower layers
• Cannas — similar rhizomatous habit with vibrant flowers
• Begonias — shade-loving foliage contrast at ground level

8. Cold Climate Strategies

Heliconia rostrata is strictly tropical, thriving in USDA Hardiness Zones 10b through 12 where temperatures rarely fall below 4°C. The foliage suffers visible damage at temperatures below 10°C, with leaves developing brown margins and tips. Exposure to temperatures of 2 to 4°C for even brief periods (2 to 4 hours) causes extensive leaf necrosis and pseudostem collapse, though established rhizomes may survive and resprout if mulched. Prolonged exposure below 0°C kills both above-ground growth and underground rhizomes completely. For gardeners in Zone 9b or marginal Zone 10a locations where occasional freezes occur, protection strategies are essential.

Before anticipated cold weather, water plants thoroughly 24 hours in advance—moist soil holds heat better than dry soil and buffers temperature fluctuations. Apply a thick mulch layer of 20 to 30 centimeters over the root zone using pine straw, shredded leaves, or straw to insulate rhizomes. For valuable specimens, construct temporary enclosures using stakes and agricultural frost blankets or burlap, ensuring the covering extends to ground level to trap soil heat. Add strings of outdoor incandescent lights (not LEDs, which produce minimal heat) within the enclosure for additional warmth during freeze events. In areas with regular winter cold below 10°C, treat H. rostrata as a summer annual or lift rhizomes in autumn: cut pseudostems to 30 centimeters, dig rhizomes with adhering soil, and store in barely moist peat or sawdust at 12 to 15°C in a frost-free garage or basement. Replant outdoors after all danger of frost has passed and soil temperatures reach at least 18°C, typically 2 to 4 weeks after the last spring freeze date. This labor-intensive approach is practical only for small collections; most cold-climate gardeners find containerization and overwintering in heated greenhouses more practical.

Hardiness Thresholds

• USDA Zones: 10-12
• Minimum Survival Temperature: 2°C (36°F)

Overwintering Options

• Rhizome Storage: Lift rhizomes after foliage dies back, dry for 1-2 days, then store in slightly damp peat, vermiculite, or wood shavings at 5-10°C. Check monthly for rot or desiccation.
• Heavy Mulch (borderline zones): Apply 15-30 cm of dry mulch (straw, leaves, bark) over the rhizome zone after the first frost. Cover with waterproof material to prevent moisture saturation. This works well for hardier species like H. schiedeana.
• Container Culture: Move potted plants indoors to a bright, cool location (10-15°C). Reduce watering significantly for dormant species.
• Greenhouse: An unheated or minimally heated glasshouse provides ideal winter protection for tender heliconias.

9. Ethnobotany & Cultural Significance

Indigenous peoples of the western Amazon basin, including the Shuar (Jívaro) of Ecuador and the Shipibo-Conibo of Peru, have incorporated Heliconia rostrata into their traditional practices for centuries, though its uses differ markedly from other more utilitarian Heliconia species. The Shuar employ the large leaves as emergency rain shelter during hunting expeditions and as temporary wrapping for wild game, appreciating the leaves' water-repellent waxy surface and substantial size. More significantly, the spectacular inflorescences feature in ceremonial contexts: the pendant red bracts are incorporated into festival decorations during harvest celebrations and coming-of-age ceremonies, where they symbolize abundance and the connection between earth and sky, reflecting the plant's unique downward-growing flowers that bridge the forest canopy and understory.

The Shipibo-Conibo communities along Peru's Ucayali River recognize H. rostrata (called shokon rao in their language) as an indicator plant for fertile alluvial soils suitable for manioc cultivation, observing that its presence signals the proper moisture and nutrient levels for successful agriculture. Women collect the dried flower bracts, which are sometimes incorporated into traditional textile dyes when combined with iron-rich mud, producing subtle rust-orange tones on cotton fabric, though this practice is less common than the use of other local dye plants. Ethnobotanical surveys conducted in the 1990s by researchers at Peru's Instituto de Investigaciones de la Amazonía Peruana documented occasional medicinal use of the rhizome sap, applied topically to treat minor cuts and abrasions, though this application lacks formal pharmacological validation.

In modern Amazonian communities, H. rostrata has gained economic significance as a cut flower crop, with smallholder farmers in Ecuador's Napo province and Peru's San Martín region cultivating the species for export to florist markets in Quito, Lima, and international destinations. This commercialization, facilitated by improved transportation infrastructure since the 1990s, has provided supplemental income to rural indigenous communities while also raising concerns among ethnobotanists about overharvesting from wild populations. Cultural knowledge transmission about the plant remains strong, with elders teaching younger generations to recognize the subtle variations in bract color and form that distinguish H. rostrata from related pendant species like H. collinsiana and H. chartacea.
