I bought today a Carissa. I had one years ago but lost it in our rare 2009 frost and have never seen another since. I also bought a nice pot for it and will plant it later. I also got two Lantana montevidensis (Creeping Lantana), one Lavender and one White. I hae not decided where to plant Them.
They are pretty when in bloom and fruiting. Now they come in thornless varieties. My last had nasty thorns ... none on this one.
