The Blood Banana is exotica at its best and one of the most beautiful of all ornamental bananas; it has to be seen to be fully appreciated!
Native to Indonesia its leaves are maroon on the undersides, heavily striped on the top and the stem is dark pink to maroon.

In America it is often used as a pool side decoration. It is not hardy at all and best grown in the UK as a summer bedding plant or house plant and overwintered in the greenhouse or conservatory.

Zebrina is very attractive and also quite fast growing. As a true banana plant, flowering and fruit is possible but unlikely under average household conditions. Keeping it in a pot or topping out at around 1.2m (4') makes it a useful specimen to keep for a longer period, without outgrowing its welcome.

Sowing:
Sow indoors at any time of year.
Sow seeds as soon as you are able. If you are not going to sow them, store them in their packaging in a cool, dark, dry place. (Do not refrigerate)

Soak seed for 3-4 days in warm water, which has been previously boiled. Change the water each day. (This process is important, as gets rid of germination inhibitors)
Fill either large cells or trays with perlite, vermiculite or sterilized compost. Stand the trays in water until the medium is completely moist
Sow the seeds 2.5cm (1”) deep. Spray the seeds with a little copper based fungicide
Bottom heat is helpful, place in a propagator if you have one or in a warm location out of direct sunlight. Do not exclude light as this helps germination. Keep at a constant temperature of 20-25°C (68-77°F).

Check the seeds daily for germination. If mold or fungus appears, remove the seeds and wash them in warm water. Spray them with fungicide and re-sow in a fresh medium in a sterilized pot.
Keep the surface of the compost moist but not waterlogged. Patience is needed as germination is erratic and take from one to twelve months. Do not give up too soon!

Growing:
When large enough to handle, transplant seedlings into 7.5cm (3 inch) pots, taking care not to damage the root system. Grow on in well-lit conditions, and pot on, into rich, well drained soil, as required. Water the plant thoroughly and every 1 to 3 days thereafter depending on the season. Do not soak! Remember moist soil, not wet, not dry.

Position:
The planting site should be chosen for protection from wind and cold weather, if possible, the south or southeast side of the house. Banana plants will grow in most soils, but to thrive, they should be planted in a rich, well-drained soil. Before planting, test your soil’s ability to drain properly. Dig a post-hole about 2 feet deep. Fill it with water. If it empties within two hours, the drainage should be ideal.

Cultivation:
Their rapid growth rate makes bananas plants heavy feeders. During warm weather, apply a balanced fertilizer once a month. Spread the fertilizer evenly around the plant in a circle extending 4 feet from the trunk. Feed container banana plants on the same monthly schedule using about half the rate for outside plants.

Overwintering:
Bring container grow plants indoors. Outdoor plants need protection, either wrap the trunk or cover with blanket if the banana plants are small and low temperatures are predicted. You can also dig up the roots, and store in a dark dry place inside until spring. (Foliage can be cut back to 6-8”) This is the best way for most.
Leaves are damaged at 0°C (32°F) but the plant will grow back from the root (corm)
