Musa Siamensis is a recent introduction into the collectors trade of ornamenatal bananas from Asia that grows to 9'. I hear it can be a little invasive but I've had no problems so far in the 3 or 4 years it's been here in my yard. It seems to like more water than the average ornamental banana, and will not grow taller than 2' nor bloom in shade. However in full sun and with ample moisture, it's foilage is a beautiful deep rich green I haven't seen before in any banana tree. I have it growing in three environments and next spring I think know what to do with it.
