One more thing for that us gardeners may enjoy. Oct. 18th and 19th is the Lady Bird Johnson Wildflower Center's Native Plant sell. Today in our staff meeting they said they would have almost 300 species of Native Texas plants for sell, and they are reasonably priced. I think there is an admission fee to go to the sale (which I find weird), but that is also your admission into the garden and hiking trails.
See http://www.wildflower.org/plantsale/ for more info, prices, and a species list.
Take this info as you wish.
