I jus bought a new begonia yesterday The tag from the WWW.begonia.org says "Thiemel". I googled it and even went to the website and notiing shows. It is a beautiful begonia.
Beautiful! How cute. It is a Palm Leaf Begonia (Begonia thiemei), also named Begonia macdougallii
Carol in Jacksonville
This is a species rhizomatous, once called macdougalli but now is correctly ID'd as B. theimei. It can get quite large. In my Tampa Bay yard, B. theimei can fill a 14" bowl and I grow it outdoors all year.
