I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
There are a number of flowers that can take your weather and it really comes down to what you like the look of. Here are a few good ones to consider planting around that bed with the bottle palm:
Blanket flower (Gaillardia pulchella)
Portulaca (Rose moss)
Vinca or Madagascar periwinkle (Catharanthus)
Yellow Bells (Tecoma stans)
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
