We have been growing this gigantic false banana from Ethiopia for decades. Its 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 Heronswoods shady valley, which was depleted of nutrients and water, we buried its herbaceous leaves and the following growth oftrees was astounding. Itscarbon level is around 4050% and itcan generate 80tonnes of carbon storage (peracre) in a year. Its just the plant for organic gardeners. Fast growth rate.
