An old cultivar but a lovely & unusual one from Grace Goode ('Vulcan' x carolinae hybrid). Small size.
Don't over water - just enough to prevent the plant from drying out & to keep fresh water in the centre.
Light shade or filtered sun / 50% shadecloth - 70% in Summer. Early am or late pm sun.
Very little or the plant will lose colour. Use a slow release fertiliser higher in potassium than nitrogen..
