Musella lasiocarpa

Without doubt, the toughest and hardiest of all ornamental bananas in the UK, it is grown for it's dramatic and tough leaves, and once mature, it's amazing and long lasting golden yellow flowers – hence it's name.
From high up in the Chinese Mountains of Yunnan, it is naturally very tough, and exposed to temperaturees well below freezing. It forms a much thicker, tougher and sturdier trunk-stem than other bananas, which is very tough and hardy. Even if leaves are damaged by frosts, more and new leaves emerge in Spring, as well as numerous 'pups' round the side.
The flower is in fact it's last hurrah, a 6 Month epic flower display, but a sign the plant will die – but fear not – you will have plenty of established pups round the side in a clump, EACH of which will grow and develop to maturity too. It is thus best regarded as a clump forming perennial.
It is also much shorter and less vigorous than other huge banana plants too at around 4-5ft tall maximum, making it ideal for large pots in small gardens – grow in full sun or shade, it makes a great talking point.
Note – it does not produce any edible banana fruit, not even tiny ornamental ones. Very easy to grow, and a great exotic looking patio focal point.
