i took this picture of a part of my rock garden that has four different species of Talinum(if that taxon still is valid) T. okanoganense, T. spinecens, T. brachypodium and T. brevifolium.
I don't know whether the names are valid but the plants are great!
Love the "talinum-orama'! They sure do well for you. Talinum okanogenense has survived for me and manages to bloom but nothing like that!
