They seem to also thrive on rather brutal ( or at least uncaring ) treatment.
My neighbour gave me clump last Autumn which I dutifully potted up ......result.....lots of leaves but no flowers.
He gave me another clump this Spring which I stuck in an old compost bag whilst I decided where to put them. I'm ashamed to say, they are still in that sack and are flowering beautifully. They had the odd bit of watering when I remembered but no other care than that
This isn't a recommendation by the way
