I planted S. ovata here in Austin TX 5 years ago after seeing it at the LBJ Wildflower Center. From one 4" pot it has spread to ~100 square feet area of the bed it is in. It has these bulbous roots that are difficult to pull up and the plant will regrow from them if they are left behind.
It is pretty and a native but in my front yard garden it is too aggressive and does not behave well. For some this may be desired but I want people to be aware so they do not end up battling this plant.

I love mine, it looks really pretty with several stems, each with a lot of flowers. I
looked up propagation from Univ. of Teaxs at Austin website & this is what they have:
"Take cuttings in fall as soon as the tips emerge. Seed works too but germination not as reliable. Plants go dormant over summer and there can be alot of loss due to rotting over the summer. Probably best to water pots infrequently over summer.
Maintenance: Gardeners cut back seedheads in early summer."
To me that only makes sense if we flip it, since this is from a much warmer zone. Please let me know if I'm wrong!!
