I bought this Hepatica last spring but it hasn't grown a millimetre, and it looks a bit sickly. What's the best way of dealing with it.
Compost heap. The compost looks a bit sour and old? Not a plant I've ever grown. Looking like the slugs have given it a hammering.
Try repotting in to a leafmould rich gritty compost. Water infrequently and leave in a relatively light area not in strong sunlight. This may kill, or cure it.
