Has anyone experience of growing Androsace x marpensis in pots ? I have two which I have had for quite a few years, and still in the same pot I am ashamed to say. They are probably desperate to be potted on and wonder if anyone can recommend a suitable compost mix? There seems very little on the net re cultivation. They seem easy enough to grow but very reluctant to flower although I think Eric Jarrett grew a very floriferous plant which won a Farrer some years ago
