I had a bed full of a few Datura's last summer and a friend that worked at a grain silo came over and asked me why I had planted all this pig weed!LOL It was a total accident as I thought it would be another pretty moonflower like my others, It was so not. I went up to his work to find it growing like a noxious weed all over behind their bins.
Well her are a few pics of my clematis with many more covered with buds that will bloom any day. Forgive me for not recalling the names of them. I would need to know the Latin language in order to keep up with all the plants we have.
This one is one of my new favorites and if I had 1 more cup of coffee, I know I could remember its name!
