We have been growing this gigantic false banana from Ethiopia for decades. It’s the fastest growing plant we know and it sequesters carbon more quickly than any other non-woody plant. When we started growing rainforest trees in Heronswood’s shady valley, which was depleted of nutrients and water, we buried its herbaceous leaves and the following growth of trees was astounding. Its carbon level is around 40–50% and it can generate 80 tonnes of carbon storage (per acre) in a year. It’s just the plant for organic gardeners. Fast growth rate.
Ensete ventricosum are fast growing, and will quickly grow into a space, as the focal point of the display. For best results, grow in a warm sunny, sheltered spot, away from strong winds, which can damage the leaves and make them look unsightly. Water regularly and feed with a nitrogen-rich fertiliser in spring.
