Have a bit of time to pass this am as I wait for a train, so am visiting you from the Stained Glass/Mosaic side of the forum. Re your question, I have two wonderful Roses of Sharon - more like trees as I let them grow tall. Blooms beautiful, and are fast growers. They also attract bees.

I set out a couple in April (San Antonio), and they've been blooming like the dickens. I haven't seen a hummingbird or butterfly go anywhere near them, though.

If you occasionally venture southwards, there's a "butterfly garden" at a new library near the intersection of 281 and 46 near Bulverde.

I hate my two rose of sharons. They just aren't pretty plants to me. The flowers are pretty, but there aren't enough to suit me. Plus it loses its leaves in winter and gets really ugly then. If you plan to be in DFW, feel free to come dig mine up! They are healthy.
