Have had several of these in full sun in the midwest for several years. They will propagate by self seeding but need sun to get going, last couple of years my beds were too full and they did not propagate and several died off. I purchased several more for this year's garden, as I like that they have a longer flowering season than most perennials, especially if you trim them back some after blooming.

Positive Handyman67 On Mar 2, 2010, Handyman67 from Columbus, OH wrote:

Grows well in sun to part shade, flowers are a very pale sky blue on light to silvery green fine leaved foliage reminiscent of asparagus fern, blooms from spring to first frost. Blooms have a tendency to drop petals in high heat. Self seeds somewhat, and can be somewhat floppy after rain, does well with little to no care after established.
