People usually call the group of banana plants emerging from a common rhizome a “mat,” but some call it a clump, and I sometimes think of it as a family. That rhizome continually sprouts up new banana plants.

Banana plants are more like giant stalks of grass that grow out of a bulb-like base called a rhizome. Neither are banana plants trees like, say, orange trees. And in fact, a friend who lives near me in the hot and dry foothills of San Diego County is producing these wonderful bananas:īanana plants aren’t individuals like, say, tomato plants. The bananas in the photo above come from a plant in the San Gabriel Valley of Los Angeles County. Nevertheless, bananas can be grown to decent production even in many parts of the valleys and foothills. (Mere frost won’t kill a banana plant, but it does slow down its fruit production by damaging leaves.) Here I’ve learned to put my bananas near a south-facing wall for the best frost protection. I’m now in the foothills, Sunset Zone 20, where we get at least a touch of frost every winter. I used to live near the San Diego Zoo where, incidentally, many bananas are also grown. I’ve grown bananas within this ideal band. This is where it’s a suitable combination of humidity and winter warmth. Think of the areas that the marine layer consistently rolls over each summer night. Bananas can be grown well and easily throughout most of Southern California between the mountains and the ocean, specifically Sunset Zones 24 down to 21 (find your Sunset zone here).
