Mine is planted in a pot. I bought it last year, and the seller said they like to be in a smallish space. It was in flower when I bought it. I potted it on this spring into a 26cm terracotta pot, with the correct soil.
It has 7 flower buds, which are just looking as if they might open, the bud tips were beginning to look a bit brownish, so I have moved it into partial shade. I water it a little each day.
Will it open out, should it be in full hot sun, or partial shade, and does it need a feed now, and if so with what ? thanks, Mrs Bouquet
