This is a great evergreen plant here in zone 10 and attracts many butterflies and flowers most of the year.

I love this shrub. It dies down to the ground every winter but comes back well. I have it placed where I don't want a huge shrub anyway :) The scent of the flowers is divine.

Edited 6/24/07: It didn't come back this year :(

This plant was not hardy in my area, zone 6a (Detroit). Some roots died off, some did'nt. It looked like half a plant, not a pleasant sight.

We love this plant. Planted it in the summer and it really has grown a lot. It has not died back yet and it is already January. This plant produces very pretty and colorful flowers that smell wonderful. This was a favorite for the butterflies and bees. Once the flowers go brown, clip them off to inspire new growth!

Has died to the ground each winter (zone 5b), but comes back strong each summer. It gets to about 3'-4' in one summer. This summer it is attracting hummingbirds.

Very good flower color. This plant should be pruned to the ground in spring, even in areas that it is wood-hardy to prevent its being over-grown and weedy-appearing.

Seeds do not come true.
