Hi, I have Nivenia corymbosa I grew from seed started in 1998. I planted one in my garden. It hasn't grown much since then and never has flowered so obviously isn't getting what it needs. The man who did the topic of the week for woody irids is no longer a member of the list so I can't ask him for help. The aristeas in my garden are reluctant bloomers too. Maybe they need more sunshine than they get since I have a lot of trees or maybe fire is needed to bring them into bloom? Mary Sue
