Thank you to edgeplot@Flickr from Seattle, Washington for sharing today's BPotD (original image | BPotD Flickr Group Pool). I'm grateful!
This is the last day of my short vacation, so only a brief entry with links today. Do visit the original image to read edgeplot's notes about this particular cultivar. I've chosen to drop the epithet boliviensis from the name, following the RHS Plant Finder's convention. Still, it is evident that Begonia boliviensis is responsible for much of the appearance of this attractive cultivar.
Wikipedia's entry on begonia is a worthwhile read. I hadn't realized that Begonia is among the ten largest genera of plants.
Daniel - care to explain further why you dropped the boliviensis epithet? This identical plant is widely cultivated here in the Bay Area as the species boliviensis, but it sounds like it might be a hybrid.
If Begonia is one of the ten largest, which are the others? I think Senecio and Euphorbia and Carex might qualify, but what else?
Eric - you might assume that the October 2005 issue of RHS's The Garden with some hints about why RHS chose to drop boliviensis would be available to me, but it still hasn't managed to find its way to the garden's library (since it is first circulated to all staff), so I can't check to see.
edgeplot - Astragalus would make the list, I think, as would Rhododendron.
Ah, the genus Acacia should also make that list. That means we're up to seven.
