Anthuriums 'Tulip' (Tulip Anthurium)
Anthuriums 'Tulip' (Tulip Anthurium)
Introduction
Anthurium 'Tulip' is a specialty group of Anthurium andraeanum hybrids characterised by cupped, tulip-shaped spathes rather than the flat, open spathe of standard anthuriums. The three-dimensional cup-shaped flowers come in red, pink, orange, white, and bicolour forms.
Anthurium 'Tulip' refers to *Anthurium andraeanum* cultivars in the Tulip Group, family Araceae. These hybrids are distinguished by their concave, cup-shaped spathes that curve inward at the edges, forming a tulip-like three-dimensional form rather than the flat, shield-like spathe of standard types. Available in a wide range of colours from deep red and orange to soft pink and white.

History & Cultural Significance
Tulip-type anthuriums are modern horticultural developments, primarily bred in the Netherlands since the 1980s. *Anthurium andraeanum* itself was introduced to Europe in 1876 from Colombia by plant collector Édouard André. Dutch anthurium breeding has produced thousands of registered cultivars.
About Flowering Houseplants
Flowering houseplants challenge the common perception that indoor plants are exclusively about foliage. Saintpaulia (African violet, Gesneriaceae) was discovered in 1892 by Baron Walter von Saint Paul-Illaire in the cloud forests of the Usambara Mountains, Tanzania — within decades it became the most popular flowering houseplant worldwide, with over 16,000 registered cultivars. Anthurium (Araceae) produces a modified leaf (spathe) surrounding a spadix covered in tiny true flowers — the glossy red 'petal' is actually a bract. Spathiphyllum (peace lily) uses a similar bract structure. Cyclamen persicum, native to Mediterranean scrublands, blooms in winter when grown cool (12–16°C).

Tulip-type anthuriums are horticultural selections from *Anthurium andraeanum* (family Araceae), native to Colombia and Ecuador. The cup-shaped spathe is a genetically fixed trait in these cultivars. All parts of the plant contain calcium oxalate crystals.
Growth Timeline
Anthuriums produce a new spathe every 4–8 weeks under good conditions. Each spathe lasts 2–4 months on the plant. Young plants may take 6–12 months to begin flowering after purchase.
Light Requirements
Bright indirect light for best flowering — 1–2 m from a south or west-facing window. Insufficient light results in few or no flowers and smaller spathes. Avoid direct midday sun which bleaches the spathe colour.
Group Light Guide
African violets, Anthurium, and other flowering indoor plants need bright indirect light to bloom reliably. 10–12 hours of bright light daily encourages continuous flowering. LED grow lights work very well. North windows are usually insufficient for flowering.
Watering
Water when the top 2–3 cm of soil is dry. Use room-temperature filtered or distilled water — anthuriums are sensitive to fluoride. Water thoroughly, then allow to drain. Never allow to sit in water. Reduce slightly in winter.
Group Watering Guide
Consistent watering is key for flowering plants. African violets prefer bottom watering to avoid crown rot. Anthurium needs moist but not wet soil. Most flowering houseplants benefit from slightly reduced watering after blooming to encourage the next flower cycle.
Humidity & Temperature
High humidity (60–80%) is ideal for the best spathe quality and longevity. Use a humidifier or pebble tray. Prefers 18–27 °C; protect from temperatures below 15 °C. Stable temperatures prolong individual spathe lifespan.
Group Humidity & Temperature Guide
African violets perform best at 50–60% RH with constant temperatures of 18–24°C; cold water drops on leaves cause ring spot (white marks). Anthurium needs higher humidity (60–80%) to maintain glossy, healthy foliage. Most flowering houseplants require stable temperatures — fluctuations greater than 8°C between day and night inhibit bud development and cause bud blast. Avoid cold windowsills at night where temperatures can drop below 12°C. Heated propagation mats help maintain constant root zone temperature for consistent blooming.
Soil & Potting
Use an epiphytic mix: 40% orchid bark + 30% perlite + 30% quality potting soil. Excellent drainage is critical. Repot every 2–3 years or when aerial roots become extensive. Choose breathable terracotta or mesh pots.
Group Soil Recipes
Flowering plants need nutrient-rich, well-draining mix: 50% potting soil, 25% perlite, 15% coco coir, 10% compost. African violets require a special violet mix or very light, airy soil. Anthuriums prefer orchid-type mix. pH 5.5–6.5. Fresh soil annually supports blooming.
| Repotting frequency | every 2–3 years (spring) |
| Pot size up | 2–3 cm larger diameter than current |
| Growth rate | slow |
| Drainage | Essential — always use pots with drainage holes |
Fertilizing
Feed every 3–4 weeks year-round with a high-phosphorus fertiliser (e.g., 10-30-20 NPK) diluted to quarter strength to promote flowering. A balanced fertiliser can be used in winter. Flush with plain water every 2 months.
Group Fertilizing Guide
Flowering houseplants need phosphorus-rich fertilizer (15-30-15 or African violet formula) for sustained blooming. Feed African violets every 2 weeks with specialized violet fertilizer — wick-watered plants benefit from constant dilute feed (quarter strength in every watering). Anthurium prefer balanced feed (20-20-20) every 2 weeks. Never fertilize newly repotted plants for 4–6 weeks.
| Spring (Mar–May) | Resume feeding every 2–3 weeks with balanced liquid fertilizer at half strength |
| Summer (Jun–Aug) | Peak feeding period — every 2–3 weeks at full dilution rate |
| Autumn (Sep–Nov) | Reduce to monthly, then stop by late October |
| Winter (Dec–Feb) | No fertilizer — plant is in rest phase, roots cannot absorb nutrients efficiently |
Propagation
Division of the rootball when repotting is the most reliable method. Each division needs its own root system. Stem cuttings with aerial roots can be potted directly. Seed propagation is complex and produces variable results.
Group Propagation Guide
African violets propagate from leaf cuttings: cut a healthy middle leaf with 3 cm petiole, insert petiole at 45° into moist perlite or vermiculite, and plantlets emerge in 6–10 weeks. Anthurium propagates by division of crowded clumps in spring — each division needs at least 2 leaves and healthy roots. Spathiphyllum divides easily when root-bound. Cyclamen propagate from seed (slow, 12–18 months to bloom) or rarely from tuber division. Most flowering houseplants root more successfully with bottom heat (22–25°C) and a clear plastic humidity dome.
| Method | Technique | Best timing | Success rate |
|---|---|---|---|
| Division | Unpot the plant, gently separate root clumps with multiple growth points. Each division needs roots and at least 2–3 stems or growing points. | Spring | Very high (95%+) |
Pruning & Maintenance
Remove spent spathes and yellowing leaves at the base. Trim brown leaf tips with clean scissors. Aerial roots can be tucked into the soil or left exposed. Do not remove healthy aerial roots.
Group Pruning Guide
Deadhead spent blooms promptly to encourage continuous flowering — pinch or cut faded flowers at the base of the flower stalk. For African violets, remove entire flower stalks once all blooms fade; remove any leaves growing into the centre of the rosette to maintain the symmetrical crown. Anthurium spathes can be removed when they turn green. Prune leggy spathiphyllum foliage at the base. Never use leaf shine products on African violets as the hairy leaves trap the product, causing cell damage.
| Pruning frequency | as needed during the growing season |
| Best time to prune | Early spring before new growth flush |
| Leaf cleaning | Monthly — wipe with damp cloth to clear stomata |
| Tool sterilization | 70% isopropyl alcohol between cuts |
| Growth rate | slow |
Common Problems
No flowers: insufficient light or phosphorus. Yellow leaves: overwatering or cold damage. Brown spathe edges: low humidity or fluoride in water. Pale spathe colour: insufficient light during development.
Troubleshooting Guide
Spathe colour fading quickly: too much direct sun. Green spathes instead of coloured: plant stressed or insufficient light during spathe development. Spathes not opening fully: low humidity.
Pest & Disease Guide
Mealybugs hide in leaf axils and root crown — treat with isopropyl alcohol. Scale insects on stems — scrape and treat with neem oil. Aphids on new growth and spathe — remove with water spray and insecticidal soap.
Group Pest Profile
African violets attract cyclamen mites (Steneotarsonemus pallidus) — microscopic pests causing distorted, hairy new growth in the crown. Treat with miticide; isolate affected plants immediately as cyclamen mites spread rapidly. Mealybugs hide in the dense leaf rosettes. Thrips damage flowers, causing brown streaks and shortened bloom life. Anthurium are susceptible to scale and mealybugs. Botrytis (grey mould) attacks spent flowers in humid, stagnant conditions — remove faded blooms promptly. Crown rot from overwatering is more damaging than any pest for African violets.
| Pest | Identification | Treatment |
|---|---|---|
| Spider mites | Fine webbing on leaf undersides, stippled yellowing leaves | Shower blast, neem oil spray, predatory mites (Phytoseiulus persimilis) |
| Mealybugs | White cottony masses in leaf axils and stem joints | Isopropyl alcohol on cotton swab, insecticidal soap, systemic imidacloprid |
| Scale insects | Brown or tan bumps on stems and leaf midribs | Manual removal, horticultural oil, systemic treatment for heavy infestation |
| Fungus gnats | Small black flies around soil, larvae in wet substrate | Allow soil to dry between waterings, BTi (mosquito dunks), yellow sticky traps |
| Thrips | Silver streaks on leaves, black frass dots | Blue sticky traps, spinosad spray, systemic treatment |
Pet & Child Safety
TOXIC to cats and dogs — the ASPCA lists *Anthurium* as toxic. All parts contain insoluble calcium oxalate crystals causing oral irritation, drooling, vomiting, and difficulty swallowing. The tulip spathe is particularly attractive to pets; keep out of reach.
Safety Precautions
| Placement | High shelves, hanging baskets, or rooms inaccessible to pets |
| Fallen leaves | Remove promptly — dried plant material retains toxicity |
| Water runoff | Drain saucers after watering — some toxins leach into standing water |
| Emergency | ASPCA Poison Control: 888-426-4435 (US) • Pet Poison Helpline: 855-764-7661 |
Display & Styling
The unique three-dimensional cup-shaped spathes of Tulip Anthuriums create an unusual, sculptural display. A cluster of 3–5 plants in bloom simultaneously creates a dramatic floral arrangement. The spathes last 2–4 months on the plant.
Group Display Ideas
Position flowering plants where their blooms can be fully appreciated. African violets make wonderful windowsill collections. Anthurium adds a tropical touch to modern interiors. Group blooming plants together to create a colorful focal point. Rotate regularly for even light exposure.
| Best position | tabletop or shelf |
| Light zone | bright indirect |
| Humidity needs | high (60%+) |
| Indoor height | 30-50 cm |
Companion Planting Indoors
The sculptural tulip spathes pair beautifully with foliage plants like *Monstera*, *Ficus lyrata*, or *Philodendron* species. The flowers provide colour contrast to an otherwise green foliage display. Avoid pairing with strong-smelling flowers that compete with the anthurium's subtle fragrance.
Seasonal Care Calendar
Spring/Summer: most vigorous blooming period. Feed with high-phosphorus fertiliser. Autumn/Winter: continue regular care — anthuriums can flower year-round in stable indoor conditions. A slight temperature drop (to 16 °C) in autumn sometimes triggers a new flush of flowers.
Group Seasonal Guide
Spring: Increase feeding with bloom-promoting fertilizer (higher phosphorus). African violets and anthuriums begin their main flowering cycle. Repot after bloom flush if needed. Summer: Maintain consistent watering — dry stress causes bud drop. Remove spent flowers promptly to encourage continued blooming. Autumn: Many flowering houseplants have a secondary bloom period. Reduce feeding but continue with bloom fertilizer if buds are forming. Winter: Supplemental lighting (grow lights, 12–14 hours daily) maintains blooming through short winter days. Cool night temperatures (15–18°C) benefit cyclamen and many other flowering species.
| Season | Watering | Feeding | Key tasks |
|---|---|---|---|
| Spring | Increase gradually | Resume every 2–3 weeks | Repot if needed, prune dead growth, check for overwintering pests |
| Summer | Most frequent | Peak feeding | Monitor for pests, rotate for even growth, increase humidity |
| Autumn | Reduce gradually | Taper off by October | Move away from cold windows, reduce watering frequency |
| Winter | Minimal | None | Maintain min. 16°C, increase light if possible, watch for dry air from heating |
Frequently Asked Questions
How often should I water my Tulip Anthurium?
Water Tulip Anthurium moderate - let top dry. During the growing season (spring/summer) this is typically every 7-10 days; in winter reduce to every 14-21 days. Always check the soil moisture before watering — insert your finger 2 inches into the soil; if it feels dry, it's time to water.
What light does Tulip Anthurium need?
Tulip Anthurium requires bright indirect. Avoid harsh direct afternoon sun which can scorch leaves. If you notice pale, washed-out leaves, the plant may be getting too much sun; leggy, sparse growth indicates insufficient light.
Is Tulip Anthurium safe for cats and dogs?
No. Tulip Anthurium is toxic to cats and dogs. Keep it out of reach of pets and children. If ingestion is suspected, contact ASPCA Animal Poison Control at 888-426-4435 immediately.
Why are the leaves of my Tulip Anthurium turning yellow?
Yellow leaves on Tulip Anthurium most commonly indicate overwatering. Check that the soil is not constantly wet and that the pot has proper drainage. Other causes include insufficient light, nutrient deficiency, or natural aging of lower leaves. Assess all factors and adjust care accordingly.
Why do my Tulip Anthurium have brown leaf tips?
Brown leaf tips on Tulip Anthurium are usually caused by low humidity, fluoride or chlorine in tap water, or inconsistent watering. Try using filtered or rainwater, increasing humidity with a pebble tray or humidifier, and establishing a more consistent watering routine.
How do I propagate Tulip Anthurium?
Tulip Anthurium is most easily propagated by division. Take cuttings in spring or early summer during the active growing season for the best results. Ensure your cutting has at least one node, use a rooting hormone for faster root development, and provide warm, humid conditions.
What humidity does Tulip Anthurium prefer?
Tulip Anthurium prefers high (60%+) relative humidity. If your home is dry, especially in winter with central heating, use a pebble tray filled with water, group plants together, or use a small humidifier nearby. Avoid misting directly on leaves as it can cause fungal issues.
Is Tulip Anthurium a good plant for beginners?
Tulip Anthurium has a difficulty level of moderate. While not the easiest houseplant, with proper care guidelines this species can thrive in home environments. Pay particular attention to watering frequency and light levels.
When and how should I repot Tulip Anthurium?
Repot Tulip Anthurium in spring when you see roots emerging from drainage holes, the plant drying out very quickly, or noticeably stunted growth. Choose a pot only 2 inches larger in diameter than the current one. Use fresh potting mix appropriate for the species and water thoroughly after repotting.
What are the most common pests on Tulip Anthurium?
The most common pests on Tulip Anthurium are spider mites (look for fine webbing and stippled leaves), mealybugs (white cottony clusters in leaf joints), and scale insects (brown bumps on stems). Fungus gnats can be a problem in overwatered plants. Treat infestations early with neem oil, insecticidal soap, or isopropyl alcohol.
