Neutral Terry On Aug 18, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote:

Amsonia is named for Charles Amson, an 18th century physician. It is reputedly deer resistant. This variety has willowy stems and leaves; the flowers are held high above the plant. Can be cut back by a third to promote a shrubbier form.

Some sources indicate it prefers moist (but not wet) soil; others indicate it is drought-tolerant.
