One plant that I had seen at one of the nurseries and liked was called Xanadu. It is a type of philodendron. It came up on the search. I put two in the front planter.
There are supposed to spread and mound, up to five feet wide and two to three feet high. I think that will be about right once it is established.
Of course that might take a while. I took out two shrubs that were playing dead. I think they were actually strangled by the air potato plant that snuck into the planter. I also took out the crown of thorns plants because I just didn't like them. i thought they might grow on me, but they didn't. Let's hope the new plants do grow for me though.
I do hope I can get some more landscaping done, but if it is not in the cards for this year, there is always next year.
