I get to buy pretty named varieties, but then loose the labels, and plant up shallow pans the current favourite being discarded bonsai pots. They are tough plants, can stay outdoors all year round, need very little attention, except rejuvenating which really means repotting young ones, and throwing out the ones which have run to seed and then die.
If anyone has empty ones lying around, they can bring them round and choose some little ones to plant up for themselves.
Here are a few different types waiting for their final containers
They also look great with just one variety planted in one pot
