You might try a post subject like "Best Tasting Fuchsia?" Instead of "Please answer". You're lucky to get anyone to click on a title like that, let alone a person who knows about Fuchsia.

I have had 'Hot Lips' in my garden going on 5 years. It has developed into a sizable shrub about 4 feet across and nearly as tall although I do prune it back pretty hard each spring. I do live in a relatively mild beachside climate but we are exposed to the occasional Arctic blast once or twice each winter. It hit the low 20's for a few days last November with no ill effect on the salvia. Hot Lips starts out with pure red flowers, so easy to see how the OP was misled. Then the bicolor flowers appear for most of the summer, becoming pure white flowers in late season. The hummingbirds don't seem to care what color the flowers are - they continue to visit it daily until it stops flowering in late October.

My Hybrid Franklin Tree froze the first winter, the mildest winter on record. (But it was near the corner of the house, where it might have gotten dripped on). It also set flower buds which then stalled out and didn't open, again like the climate here isn't right for it at all. I've seen the Gordonia parent growing wild and making dramatic specimens in a USDA 9 part of Florida, where it occurred on sand along with oaks, pines and native heaths that reminded me of manzanitas. In the part of the preserve I visited where I saw these it looked like the plants were coming out of an ocean beach. Other kinds of trees native to that same park that were also species we see planted and succeeding here - such as sweet gum, sugar maple and sweet-bay magnolia - were living instead in a dark muck like soil that was slightly below the level of the sand, mostly right next to the pond.

According to the book "Fuchsia Species" by Dave Green, they are different. There are subspecies listed for both. On a very quick look for differences in the descriptions I find that microphyla is characterized by branchletts at right angles, tube 7 to 10 mm long. Thymifolia is characterized by white ampliate tube, buds with divergent tips. tubes 2 to 5 mm long. The description varies a lot among subspecies, and there are natural hybrids between the two species. If you can find a copy of the book you can dig deeper. I've spent several weeks trying to identify a couple plants I have.
