Young plants of Musa thomsonii are extremely attractive having a slender, graceful habit. The pseudostems and long leaf stalks are heavily waxy and contrast well with the emerging leaves which are uniformly stained red below. The upper surface of the leaf is plain green, somewhat glossy and with blue or purple tones in the midrib channel.
Musa thomsonii is thought to be a low altitude plant, reportedly growing at a little less than 500m, and so is not likely to be particularly cold tolerant. No-one has any experience with the plant yet so it is too early to be definitive about this but until the plant is better known we are suggesting it be treated as a greenhouse subject. The seedy fruit of Musa thomsonii is reported to have sweet flesh but the hard seeds would have to be removed, a rather laborious process, in order to render the flesh palatable. Musa thomsonii is likely to be quite a large banana up to about 4 m tall overall at flowering so a rather large greenhouse or conservatory would be required to fruit it in the UK. However, young plants can easily be grown in containers and kept small by cutting back overgrown stems
