I would like to grow this but I think it just takes too much water for the Northern Colorado climate. I have tried and they always die. They look very pretty in pictures though. This is probably a good plant for places with more rain.

This plant is the backbone of my garden. During construction, several of them got run over by trucks, people, pieces of roofing etc -- and yet there was still one plant sitting there amongst the tire track ruts, healthy and very much alive. How can you not love this guy? I do not consider at as a drop-dead specimen plant, but such a great addition to any planting.

Be sure to cut back faded flower stalks. Extra water may be needed in dry periods. Divide after 3-4 years in spring or fall. Astilbe requires a lot of nutrients, so give it some fertilizer at least once per growing season.
