I grow cannas and Opuntia but cannas can not deal with our drought they look horrible right now. our clay soil is the sticky red stuff that when wet will add 20lbs to your boots and when dry turns I to a brick. I don't think many of our native plants are equipped to handle a drought of this extent. When I took the kids to school this morning almost every tree I passed was yellow and even roadside weeds in the ditches are drying up. One good thing is I have not gotten bit by any mosquitoes in almost 2 months.
