Overview
- Common Name: Red Banana, Abyssinian Banana
- Botanical Name: Ensete ventricosum ‘Maurelii’
- Type: Ornamental banana plant
- Family: Musaceae (banana family)
- Hardiness Zones: USDA 9–11 (can be grown as annual or overwintered indoors in cooler zones)
- Height: 6 to 15 feet (can grow taller in tropical conditions)
- Spread: 4 to 10 feet
- Growth Rate: Fast-growing
Unlike true bananas (Musa spp.), red banana trees like Ensete ventricosum ‘Maurelii’ are mostly grown for their striking burgundy-red foliage rather than edible fruit. Their leaves are large, paddle-shaped, and dramatically flushed with red, maroon, and green—making them a popular choice in tropical and container gardens.
Light Requirements
- Full Sun (6+ hours per day) is ideal for bold color and fast growth.
- In very hot climates, some afternoon shade helps prevent leaf scorch.
- Indoors, place near a bright, south- or west-facing window.
Soil Needs
- Prefers rich, well-draining soil.
- A loamy mix with lots of organic matter (compost, aged manure) works best.
- Ideal pH: Slightly acidic to neutral (6.0–7.0).
Tip: If planting in containers, use a high-quality potting mix with added perlite for drainage.
Watering
Red banana trees love moisture but hate soggy roots.
- Water regularly, especially during the growing season (spring–summer).
- Keep soil consistently moist, not wet.
- In containers, water until it runs out the bottom, then allow the top inch to dry before watering again.
- Reduce watering in fall and winter when growth slows.
Temperature and Humidity
- Loves warmth: Ideal range is 70–85°F (21–29°C).
- Sensitive to cold: Growth stops below 50°F (10°C), and freezing temps will kill the plant.
- High humidity (50%+) helps keep foliage lush. Mist leaves or use a humidity tray indoors.
Fertilization
- Feed every 2–3 weeks during the growing season with a balanced, water-soluble fertilizer (e.g., 10-10-10).
- Alternatively, use a slow-release fertilizer at the beginning of the season.
- Avoid over-fertilizing, which can lead to burned roots or weak growth.
Pruning & Maintenance
- Remove old or damaged leaves regularly to keep the plant looking tidy.
- Cut leaves at the base, close to the trunk.
- For container plants, repot annually or when root-bound—usually in early spring.
Overwintering
In zones below USDA 9, you’ll need to bring the red banana indoors or protect it:
Option 1: Grow as an Annual
- Let it die off in fall and replant a new one next spring.
Option 2: Overwinter Indoors
- Before frost, dig up the plant and pot it.
- Trim leaves to about 6 inches.
- Store in a bright, cool location (around 50°F/10°C).
- Water sparingly—just enough to keep roots barely moist.
Option 3: Dormant Storage
- Dig up and store the bare root rhizome in a cool, dark place (like a basement).
- Replant in spring after last frost.
Pests & Problems
Red banana trees are relatively pest-free, but watch for:
- Spider mites: Look for stippled or dusty leaves. Increase humidity and rinse leaves.
- Aphids: May cluster on new growth. Spray with neem oil or insecticidal soap.
- Root rot: Caused by poor drainage or overwatering. Always use well-draining soil.
Does it Produce Fruit?
- Ensete ventricosum ‘Maurelii’ is not grown for edible fruit.
- While it can technically flower and fruit after several years, the fruit is small, full of seeds, and not edible.
- It’s primarily appreciated for its spectacular foliage and architectural form.
Container Growing Tips
Red banana trees are excellent in large pots on patios or decks:
- Choose a container at least 18 inches wide and deep.
- Use a heavy pot to prevent toppling (these plants get top-heavy).
- Make sure the pot has good drainage.
- During winter, bring containers indoors before frost.
Landscape Design Ideas
Use red banana trees to add bold, tropical flair:
- As a focal point in tropical or contemporary garden designs
- Paired with other dramatic foliage plants like canna lilies, elephant ears, or castor bean
- In large containers flanking entrances, pools, or patios
- As a backdrop in mixed beds or borders
The deep red leaves contrast beautifully with lime green, gold, or variegated foliage.
Propagation
Red banana trees are typically propagated by: Seed:
- Difficult and slow; seeds have hard coats and low germination.
- Must be soaked and scarified, then planted in warm, moist conditions.
- Tissue Culture (Commercial)
- Most red bananas on the market are propagated via tissue culture.
- Ensete does not produce suckers or pups like true banana plants.
In home settings, it’s easier to buy a new plant than propagate this species.
Common Problems & Fixes
| Problem | Cause | Fix |
|---|---|---|
| Brown leaf edges | Low humidity or under-watering | Mist leaves or increase watering |
| Yellowing leaves | Overwatering or poor drainage | Improve soil and reduce watering |
| No growth | Cold temperatures or low light | Move to warmer, brighter location |
| Toppling over | Shallow roots, wind, or too much top growth | Stake plant or repot in a heavier container |
Fun Facts
- Native to the highlands of East Africa, especially Ethiopia.
- The species name ventricosum means “swollen,” referring to the bulbous base.
- Red banana is non-invasive, making it ideal for controlled garden settings.
- In traditional Ethiopian agriculture, the wild Ensete is cultivated as a food crop, but not the red ornamental variety.
