I was recently at the Naples Zoo and they have a plant labeled Rose Mound. Latin name is listed as Dombeya acutangula 'seminole'. That's exactly how they have it. The single quotes would make me think cultivar, but then they don't capitalize the name. And looking at the entries in the database got me more confused. Then, I tried Google and it seems that some people list seminole as the species name which seems odd. Help is much appreciated!

There's good reason for your confusion. There is a man-made hybrid species named Dombeya x seminole. There was an entry for it in our database, but I deleted it because we don't list hybrid taxa unless they're spontaneous crosses, occurring in the wild. Dombeya acutangula probably was one of the species involved in the cross. Some sites list it as Dombeya burgessiae 'Seminole,' so that probably is the other species involved.

I think the best solution is to enter it as a cultivar, with no species listed. Here's an entry for it:

Tropical Rose Hydrangea (Dombeya 'Seminole')

Thanks, Zuzu. It's a gorgeous plant and was really attracting the pollinators so I wanted to add it but I was so confused! Thanks for clearing that up!
