The golden lotus banana (Musella lasiocarpa), also called Chinese yellow banana, is among the hardiest ornamental bananas. Some reports claim it can survive down to 0°F. While hard to believe, it’s not impossible considering that it is believed to originate from the mountains of southwestern Yunnan province, China, where it was found at elevations up to 7,500 feet. Now extinct in the wild, it is still widely cultivated in China and Vietnam, often as fodder for pigs.
Hardiness in this context refers to the ability of the underground structure (the corm) to survive. The leaves are as tender as those of any banana; they “fry” at temperatures just below freezing.
Our golden lotus banana tripled in size last year. The central trunk now has a diameter of 9 inches at the base and there are a couple of dozen offspring, called “pups,” that grow in a tight cluster all around it. I don’t know when it will bloom, but eventually a swollen bud will arise from the main trunk and expose the artichoke-like golden lotus “flower” this plant is named after. Check this blog post for a detailed description.

This past winter, the leaves of our plant suffered the usual frost damage. I cut off the dead parts last weekend, and new leaves are already pushing out. Our plant certainly seems to be loving all the rain we’ve been having. In a few months, it will look as good as it did last year.

I bought our golden lotus banana at a UC Davis Arboretum plant sale three years ago—just one short trunk in a 1-gallon container. At the time it was considered a fairly unusual plant, but I’m happy to say that its availability has definitely improved since then. I’ve even seen it our local ACE hardware store.
While not as tall and impressive as other bananas, Musella lasiocarpa is ultimately a more rewarding plant for us gardeners below zone 10 because we don’t have to dig it up and store it inside for the winter. In addition, it’s a compact plant (about 4 feet in height) and hence a lot more versatile to use in the landscape than a 15 feet Musa or Ensete.

Note: The golden lotus banana is not a true (i.e. edible) banana (genus Musa) but it is closely related.
