1. Introduction & Taxonomy

A showstopping ornamental that transforms any planting scheme into a tropical paradise, Musa sp. 'Makira Blood' is a member of the family Musaceae (the banana family), belonging to the order Zingiberales.Musa sp. 'Makira Blood' is notable for reaching 5 m in height, its distinctive black pseudostem, producing edible fruit.

A most exhilarating discovery from rainforests on the remote Island of Makira in the Solomon Islands, this banana has perhaps the most intensely colored sap of any plant. It is a medium-sized plant that produces small clusters of slender, black pseudostems to about 5 m tall. When cut it can be seen that the stem is intensely deep black throughout, with purplish to dark red sap dripping out. The inflorescence has green bracts and produces fruits that not only turn bright red when ripe but that also have red flesh that is edible and fairly decent tasting. Musa sp. 'Makira Blood' will grow best in tropical climates and should make a ornamental plant.

Discovered in the remote rainforests of Makira Island in the Solomon Islands, Musa sp. ‘Makira Blood’ is one of the most visually distinct bananas ever found. Its name refers to the intensely deep red to purplish sap that oozes from any cut surface — perhaps the most intensely coloured sap of any plant species. Combined with pseudostems that are jet black throughout their entire cross-section, bright red ripe fruits with red flesh, and an altogether dramatic appearance, this undescribed species has become one of the most coveted collector's bananas in the world.

2. Biology & Physiology

Pseudostem Architecture

Like all true bananas, Musa sp. 'Makira Blood' produces a characteristic pseudostem — a notable feat of botanical engineering using only overlapping leaf bases. The pseudostem exhibits a distinctive black coloration that adds to its ornamental appeal.

Leaf Morphology

The leaves of Musa sp. 'Makira Blood' are large, oblong leaves. The leaves emerge in a spiral arrangement, each one unfurling from a compact cylinder into its full, impressive spread.

Growth Pattern & Life Cycle

• Mature Height: 2-5 m
• Growth Habit: Clustering / Suckering
• Life Cycle: Perennial through its underground rhizome (corm). Individual pseudostems complete their lifecycle after fruiting (typically variable), but the corm continuously produces new suckers (pups) that maintain the clump indefinitely.
• Growth Rate: Fast under optimal conditions, with new leaves unfurling at regular intervals throughout the growing season

Notable Adaptations

The most striking anatomical feature of Musa sp. ‘Makira Blood’ is the distinct pigmentation that pervades the entire plant. Cross-sectioning the pseudostem reveals tissue that is intensely deep black throughout — not merely the outer sheaths, but the entire internal structure. When cut, dark purplish to deep red sap drips from the wound, staining everything it touches. This level of anthocyanin accumulation is essentially unique among bananas and is of significant interest to plant biochemists studying pigment biosynthesis. The inflorescence has green bracts (a surprisingly subdued feature given the plant's otherwise dramatic colouring), producing fruits that turn bright red when ripe. Remarkably, even the fruit flesh is red — edible and reportedly fairly decent tasting.

3. Reproduction & Propagation

The primary propagation method for Musa sp. 'Makira Blood' is: Seeds and/or suckers.

Seed Morphology

• Seed Size: variable
• Shape: rounded
• Color: dark brown to black

Seed Pre-Treatment

Scarification

Mechanical scarification recommended.

Soaking

24-48 hours in warm water. This softens the seed coat and promotes imbibition (water uptake), a critical step for initiating the germination process.

Germination Protocol

Substrate

Well-draining seed compost. The substrate must retain moisture while providing excellent drainage — waterlogged conditions rapidly cause seed rot.

Temperature

Optimal: 25-30°C. Bottom heat from a propagation mat significantly improves results. Alternating day/night temperatures can mimic natural conditions and enhance germination.

Expected Timeline

4-12 weeks. Germination in Musaceae is notoriously erratic — seeds from the same batch may germinate weeks or months apart. Do not discard pots prematurely.

Success Rate

Variable. Seed freshness is the single most important factor — always source the freshest seed available. Viability declines significantly with storage time.

Light During Germination

Not critical. After emergence, provide bright indirect light, gradually acclimatizing seedlings to stronger conditions over 2-3 weeks.

Species-Specific Propagation Notes

As an undescribed species from a remote oceanic island, specific germination data for Musa sp. ‘Makira Blood’ is limited. Standard wild Musa germination protocols should be applied: mechanical scarification of the hard seed coat, 24–48 hour warm soak, and sowing at 25–30°C in moist, well-drained substrate. The species forms small clusters, so vegetative propagation via sucker division is also possible from established plants. Given the scarcity of this species in cultivation, every seed is precious — use sterile technique and optimal conditions to maximise germination rates.

4. Cultivation Requirements

Soil

Rich, fertile, well-draining soil with abundant organic matter is essential. Bananas are gross feeders that deplete soil nutrients rapidly during their vigorous growth phase. A slightly acidic to neutral pH (5.5–7.0) is ideal.

Watering

Consistent, abundant moisture is critical during the active growing season. Banana pseudostems are approximately 93% water, and the large leaf surface area results in significant transpiration losses. Water deeply and regularly, aiming for consistently moist (but never waterlogged) soil. Reduce watering significantly during winter dormancy or cool periods when growth slows.

Light Requirements

Full sun to light shade — a minimum of 6–8 hours of direct sunlight daily produces optimal growth. Young seedlings benefit from some protection from intense midday sun. In extremely hot climates (above 35°C), afternoon shade prevents leaf scorch and excessive water loss.

Temperature

• Optimal Growth: 20–30°C (68–86°F)
• Minimum Tolerance: -4°C
• USDA Hardiness: Zones 8-11

Fertilization

Feed heavily during the growing season with a balanced fertilizer (NPK 10-10-10 or 8-10-8). Potassium is particularly important for strong pseudostem development and flowering — supplement with potassium sulphate (K₂SO₄) or banana-specific fertilizer. Apply every 2–4 weeks during active growth, or use slow-release granules. Mulch generously with organic matter to provide steady nutrient release and moisture retention.

Species-Specific Growing Conditions

As a species from the lowland tropical rainforests of the Solomon Islands, Musa sp. ‘Makira Blood’ requires warm, humid tropical or subtropical conditions for optimal performance. Provide consistent warmth (22–32°C), high humidity (above 70%), and protection from wind, which damages the large leaves. Rich, humus-laden soil with regular watering and feeding produces the most vigorous growth and the most intense pigmentation. The black pseudostem colouring is best developed in strong light with adequate nutrition — stressed or nutrient-deficient plants may show reduced pigmentation.

5. Diseases & Pests

Disease data specific to Musa sp. ‘Makira Blood’ is unavailable, as the species remains scientifically undescribed and has had minimal exposure to standard banana pathogen screening. General precautions for wild Musa species apply: assume potential susceptibility to Fusarium wilt, Sigatoka, BBTV, and nematodes. The intense anthocyanin content of the pseudostem tissues may confer some degree of innate resistance to certain fungal pathogens, as anthocyanins have documented antifungal properties, but this remains speculative.

Major Diseases

Panama Disease (Fusarium Wilt)

Caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc), this is the most devastating banana disease globally. The pathogen enters through the roots and colonizes the vascular system, causing progressive yellowing and wilting of older leaves, followed by collapse of the pseudostem. Internal cross-sections reveal characteristic brown to reddish-brown discoloration of the vascular bundles. There is no chemical cure — infected soil remains contaminated for decades. The Tropical Race 4 (TR4) strain is currently spreading worldwide and threatens all susceptible cultivars.

Sigatoka Leaf Spot Complex

Black Sigatoka (Mycosphaerella fijiensis) and Yellow Sigatoka (M. musicola) cause progressive leaf necrosis, dramatically reducing photosynthetic capacity and fruit quality. Symptoms begin as small yellowish-green streaks on the lower leaf surface, progressing to dark brown or black lesions with grey centers. Remove and destroy affected leaves promptly to reduce inoculum.

Banana Bunchy Top Virus (BBTV)

Vectored by the banana aphid (Pentalonia nigronervosa), BBTV causes stunted, bunched leaves with characteristic dark green “dot-dash” streaks along the leaf veins and midrib margins. Infected plants never recover and must be destroyed to prevent spread. Control aphid populations proactively.

Common Pests

• Banana Weevil (Cosmopolites sordidus) — Adults are nocturnal; larvae bore extensive tunnels through the corm, severely weakening the plant. Use pseudostem traps for monitoring and mass trapping.
• Nematodes — Root-lesion nematode (Pratylenchus coffeae) and burrowing nematode (Radopholus similis) damage root systems, reducing nutrient and water uptake.
• Spider Mites — Particularly problematic in dry conditions and on indoor plants. Fine webbing on leaf undersides is diagnostic. Increase humidity and apply miticides if severe.
• Thrips & Aphids — Can damage emerging leaves and vector viral diseases. Monitor regularly and treat with insecticidal soap or neem oil.

Additional Disease & Pest Considerations

Given the extreme rarity and collector value of this species, a precautionary approach to disease management is essential. Maintain strict quarantine from commercial banana collections, use sterile substrates and tools, and monitor for any signs of viral infection (mosaic patterns, bunchy top symptoms, or unusual leaf distortion). If in doubt, sacrifice a leaf for laboratory testing rather than risk losing an irreplaceable plant.

6. Indoor Growing Guide

At approximately 5 m mature height, Musa sp. ‘Makira Blood’ is too large for permanent indoor cultivation in most settings. However, young plants make extraordinarily dramatic indoor specimens — the jet-black pseudostems and the knowledge that they contain blood-red sap make this a conversation piece like no other. Grow in a 20–40 L container in a warm, bright location with high humidity.

Container Selection

Choose a heavy, stable container with multiple drainage holes. Plastic pots retain moisture better; terracotta provides superior aeration. Ensure the pot is large enough to accommodate the vigorous root system — root-bound bananas grow slowly and may fail to flower.

Indoor Light

Bananas demand intense light. Place near the brightest window available — south-facing (Northern Hemisphere) or north-facing (Southern Hemisphere) is ideal. During winter months when natural light is insufficient, supplement with full-spectrum LED grow lights for a minimum of 12–14 hours total daily light. Rotate the pot quarterly for even growth development.

Humidity & Air Circulation

Maintain humidity above 60% (ideally 70–80%). Indoor environments with central heating or air conditioning are often critically dry (20–30% RH). Use humidifiers, large pebble trays, or regular misting. Grouping tropical plants together creates a beneficial microclimate. Ensure adequate air circulation to prevent fungal issues — avoid stagnant air.

Indoor Care Calendar

• Spring: Resume regular feeding and increase watering as growth accelerates. Repot if root-bound.
• Summer: Peak growth period — water abundantly, feed every 2 weeks, provide maximum light. Move outdoors if possible.
• Autumn: Gradually reduce feeding and watering. Bring outdoor specimens inside before first frost.
• Winter: Minimal growth — water sparingly (keep barely moist), stop fertilizing. Supplement light. Watch for spider mites and scale.

Species-Specific Indoor Tips

To maintain the intense black colouration of the pseudostem indoors, provide the strongest light available. Supplemental LED grow lights are essential during winter months. Keep temperatures above 18°C at all times; this tropical species shows no tolerance for cool conditions. Humidity must remain above 65% — use a humidifier or place in a bathroom with natural light. Feed heavily during the growing season with a balanced fertilizer supplemented with potassium for strong pseudostem development.

7. Landscape Use & Design

In tropical and warm subtropical landscapes, Musa sp. ‘Makira Blood’ creates an impact unlike any other plant. The jet-black pseudostems provide year-round architectural drama, while the bright red fruits and the knowledge of the blood-red sap within add layers of botanical intrigue. A single established clump draws the eye irresistibly and generates more questions from visitors than perhaps any other garden plant.

Design Applications

• Statement Specimen: Plant as a standalone centerpiece in beds, lawns, or courtyards for maximum architectural impact
• Tropical Border: Combine with cannas, heliconias, gingers, and elephant ears (Colocasia/Alocasia) for layered jungle texture
• Poolside & Patio: Creates an instant resort atmosphere; the large leaves provide light, dappled shade
• Container Feature: Large decorative pots on terraces allow flexible placement and easy overwintering
• Screening: Suckering species form clumps that provide effective seasonal screening

Companion Planting

Create stunning tropical compositions by pairing with:

• Tree Ferns (Dicksonia, Cyathea) — structural understory contrast
• Cannas — complementary bold foliage with vibrant flowers
• Elephant Ears (Colocasia, Alocasia) — bold foliage contrast at ground level
• Strelitzia (Bird of Paradise) — exotic flower accents
• Hardy Gingers (Hedychium) — fragrant flowers and lush foliage
• Bamboo (clumping types) — vertical screening and wind protection

Species-Specific Design Ideas

Position where the dark pseudostems can be silhouetted against lighter backgrounds — pale walls, bright green lawns, or silver-foliaged plants like Bismarckia nobilis or Brahea armata. Uplighting at night transforms the black pseudostems into a gothic sculpture. Pair with red-flowered heliconias, Alpinia purpurata, and dark-leaved Colocasia for a dramatic, dark-themed tropical planting. Avoid placing in deep shade, which reduces the intensity of the black pigmentation.

8. Cold Climate Strategies

As a lowland tropical species from the equatorial Solomon Islands, Musa sp. ‘Makira Blood’ has essentially zero cold tolerance. The corm and pseudostem are damaged by any exposure below approximately 5°C. In temperate climates, grow exclusively in containers and move indoors well before autumn temperatures drop to 10°C. Overwinter in a heated location (minimum 15°C) with supplemental lighting.

Hardiness Thresholds

• USDA Zones: 8-11
• Minimum Survival Temperature: -4°C (rhizome/corm)
• Foliage Damage Begins: 0°C (32°F) for most species

In-Ground Protection (Zones 7b–9)

1. After the first frost blackens the foliage, cut the pseudostem to 60–90 cm (2–3 ft)
2. Create a wire mesh cage around the remaining stump, 60 cm wider than the plant on all sides
3. Fill the cage with dry straw, shredded leaves, or hay
4. Cap with a waterproof cover (tarp, inverted pot, or plastic sheet) to prevent moisture saturation
5. Remove protection gradually in spring once consistent night temperatures exceed 5°C (41°F)

Overwintering Options

• Heavy Mulch + Wrap: For established in-ground plants in borderline zones. Apply 30–60 cm of mulch over the crown.
• Lift & Store: Dig up the corm, trim all roots and foliage, store in a cool, dark, frost-free location (5–10°C / 41–50°F) with minimal moisture for 4–5 months.
• Container Culture: Move potted plants to a bright, cool indoor location (10–15°C). Reduce watering to near-minimum.
• Greenhouse: Unheated or minimally heated polytunnel/glasshouse provides ideal winter protection.

Additional Winter Protection

Unlike deciduous or cold-hardy bananas where the strategy involves dormancy, Musa sp. ‘Makira Blood’ must be kept actively growing through winter. Reduce watering slightly and cease fertilizing, but maintain warmth, light, and humidity. A heated greenhouse or warm conservatory is ideal. If space is limited, even a single juvenile plant maintained indoors preserves this genetic material through winter for outdoor planting the following summer.

9. Ethnobotany & Cultural Significance

The Solomon Islands, an archipelago of nearly 1,000 islands east of Papua New Guinea, harbour notable banana diversity, including several undescribed species found nowhere else on Earth. Musa sp. ‘Makira Blood’ is native to the island of Makira (formerly San Cristobal), the southeasternmost of the major Solomon Islands. The island's rugged, heavily forested interior remains one of the least accessible places in the Pacific. While specific ethnobotanical documentation for this particular taxon is unavailable, wild bananas in the Solomon Islands are integral to traditional subsistence systems. The fruits of wild Musa species are consumed either raw or cooked, particularly when cultivated varieties are scarce. The red sap of ‘Makira Blood’ would likely have been noted by indigenous people, as coloured plant saps are widely used as dyes, body paints, and in traditional medicine across Melanesia. Red pigments in particular hold cultural significance in many Pacific Island societies, associated with vitality, warfare, and spiritual power. The leaves, as with all bananas in the region, serve multiple practical purposes: cooking wrappers for the traditional earth oven (motu), temporary shelters, and biodegradable plates. The scientific and horticultural discovery of this species highlights how much of the world's botanical diversity remains undocumented, even in the 21st century.
