I'd really like to plant an amsonia this year for the butterflies. I really like the color and the blooms in general. There are lots of different species of ansomia. Which kind do the butterflies prefer the most for you??
The best selection of Amsonia's that I have found is the Lazy S Farm and Nursery. I have been growing the Amsonia tabernaemontana (Blue Dogbane-Willow Blue Star) and it is a plant with nice foliage and long lasting blooms. Blooms are of an over-flexed star shape and an unusual pale blue. It is stated that it is a host plant for the Coral Hairstreak but, so far, I have not had a Coral Hairstreak in my garden.
