Best bee attracting plant I have is the Dombeya X Seminole. Blooms in the fall and is covered in bees. Second best is the flower bracts to my hurricane palms. Only problem there is that the white fly loves the palm and had to use a systemic last year, so I cut the bracts off.

From the name of this article, I thought it was another calling from Mrs. Taryn Evans, who has been a 'local' crusader for native pollinators. But while this article talked about providing pollen sources and not disturbing homes, it fell short of mentioning providing homes for the natives, aka Bee Houses.

I first heard... er... read about Bee Houses while flipping through a publication from the Wildlife Habitat Council/Audubon Society and then shortly after heard about Mrs. Evans giving a 'class' on these Bee Houses, which she builds and sells, at a local FNPS chapter meeting... which I missed. There are a few websites with general guidelines on building Bee Houses to not only 'invite' the native pollinators, but encourage them to stick around.

Here is a link that might be useful: Building Your Own Bee House

Best bee-attractor I have here is the Golden Dewdrop. I get fat bumblies just about year-round!
