Thalictrum

Wow, how lovely, and so tall, what a statement.

It is very hardy and has leaves a little like aquilegia. I don't stake it - relying on support from surrounding perennials - that way it looks more natural.

Its gorgeous, are there any other colours?

There are other colours but they tend to be coarser and flower at different times. I think this is by far the best - Thalictrum Hewitt's Double

Have put it in my favourites to remember for next year.
