Answer: The plant you're seeking may be Amsonia ciliata. It has beautiful foliage and flowers early, with lacy blue flowers of icy blue on upright stems. The blue of the bud before bloom is more intense. Foliage is dark green, long and slender, on stems up to 3-4 feet in height. Good foliage to the base of the plant even late in the season. Stems arch as they heighten after bloom.
