When shopping at a local nursery tonight, we saw something new in cuphea---Cuphea ignea variegata:
While variegated leaves don't mean anything to a hummingbird, it's nice to have something different just for a change and after years of gardening with the same old cuphea. I was not aware that variegated leaves on Cuphea even existed.
I do realize that Cuphea ignea has flower tubes that are often too slim and tight for a Ruby-throat's bill, but these flowers looked about the same as 'David Verity' or 'Vermillionaire', which is why I purchased this plant.
Additionally, we found many other good hummingbird plants including:
-Salvia guarantica 'Black and Bloom' and 'Black and Blue'
-Salvia 'Wendy's Wish'
-Arctic Blaze Purple Salvia
-Salvia greggii 'Radio Red'
