I guess I'm a zone pusher also. I grew up on the Coast of MS and always try to grow some of the plants I remember from there. Also a MG, but not active anymore. I have plumerias, musas, hibiscus, citrus, and more....but all have to be sheltered in winter. We have very few freezes, but they're usually accompanied by rain and sleet. I had quite a few palms, but last winter was... the last... for the last of them....!
Jim...our garden club is hosting Dr. Larry Noblick, Palm Biologist, from the Montgomery Botanical Garden in October. Are you familiar with him? He's coming to speak about native palms, and to make a couple of trips to collect Sabal minor seeds while he's here.
