These have been together for over six months and as you can see they're all out of sync as far as who should be watered or not. They arrived in sept. bare root. Growing indoors under lights. All looked to small to be of blooming age except perhaps the one that has now bloomed very very late in the season. It hadn't split along with the others you can see so I gave them, individually, water. Overnight the bloom forced its way out. I also let the temp inside drop lower to encourage the non splitters. It'll be tricky to keep this arraignment successfully but I like it.
