Musa ‘Siam Ruby’ grows in the wild in Indonesia but seems to have originated in Papua New Guinea according to research. It would be a wild subspecies of Musa acuminata.
It is not resistant to frost, but with its beautiful leaves, it is a nice addition to the garden.
The leaves are paddle-shaped, dark ruby color with yellow-green spots and, in rare cases, white and pink. The leaves are usually at a slightly higher angle than most species of Musa.
Flowering occurs after 9-18 months. The fruits are sweet and contain sterile or not very fertile seeds.
It grows up to 2.5-3 m high and produces suckers.
