The no fail things I have done have been hydrangeas and confederate rose, they do very well. I did also have some Wisteria vine do very well. The thing is I didn't want the Wisteria to start with, I don't like viney things to much even though I do have a lot of Jasmine, it is a lot of work to keep it trimmed, it grows like mad. I just lay my Azalea limbs on the ground and cover them with soil and they root, I tried that with my Snowball tree and still it did not root. I can occasionally get a rose to root, but I don't like to plant own root roses here, they don't do very well. I do have a few I started still in pots, and they have stayed very small.
