During the fall of 1942, my friend Leslie Hubricht brought to my attention a dried specimen of an Amsonia which he had collected in Garland County, Arkansas, and which he considered distinct from the narrow-leaved Amsonia of the "bald knobs"of the Missouri and Arkansas Ozarks currently treated as A. ciliata var. filifolia Wood. At the time, I was quite sceptical and insisted upon waiting until living plants, which Mr. Hubricht had thoughtfully obtained, had bloomed in the experimental plots of the Missouri Botanical Garden. These plants have now bloomed, and a comparison with the plants from the bald knobs, which we have had growing in the Garden for many years, completely vindicates their separation.
2011 Perennial Plant of the Year (Perennial Plant Association).
I purchased a 1-gallon plant from Nurseries Caroliniana in October 2010 and planted it in the 'One Of Everything' garden. It bloomed sparsely the first spring but in spring 2012 it put on a much better show, starting to bloom in mid april and continuing into May.
