From the 1928 Lee R. Bonnewitz Iris and Peony catalog of Van Wert, Ohio:
LENT A. WILLIAMSON (Williamson). One of the very best Irises in the world. The standards are broad and of a soft lavender-violet. The very large falls are of velvety royal-purple, and it has a brilliant orange beard. This wonderful Iris certainly deserves a color plate, and when it can be shown in all its beauty, we believe it will be one of the best selling varieties. Excellent for landscape use and also for interior decoration. $0.75

Introduced prior to 1920 when AIS was formed, this iris received it's awards from the both the national societies of France (CM 1924) and England (AM 1929).

While a handsome bloom initially, here it gets a bit dull looking in a short time.... and that phase lasts awhile. I have tried it up-front, in the back, now out to the roadside. But I do keep trying to find the right spot for it!

A tried and true variety I often see in older gardens. Rescued my rhizomes from a bulldozed home site and watched them grow into a healthy clump in two years; these guys are survivors. The blooms are faintly fragrant and there are numerous blooms on each stalk.
