I have only had Dragon's Eye for one year. I bought it last summer as a potted plant from a local nursery and planted it in late summer. It came through the winter with flying colours, and also had no problems coping with the very late spring that included several bouts of freezing rain which deposited a lot of ice. It multiplied and bloomed very well this summer considering it was just planted last year. I have it at the front of a border along a walkway, and it is a beautiful spot of colour. This is a cultivar that has performed very well in its first year and I expect it will be a great asset to the garden.
