Gardeners' Notes:

Positive grannymarsh On Jun 7, 2006, grannymarsh from Marquette, MI (Zone 5a) wrote:

the HIPS Site has the following description:
Denis, 1912

TB 33" From Bonnewitz Iris catalog for 1926: "We are told this French name means 'half-mourning' so you must not expect this Iris to contain bright colors. S. pansy-violet shaded copper; F. red-violet with white markings; yellow beard stippled brown."

33" stalks with the dainty flowers about 3 1/2" tall. This plant is in dappled shade for several hours during the heat of the day. These were purchased from Superstition Iris several years ago and this is the first year they've bloomed.

This species is rather short. They almost get as tall as the SDB's and occasionally as tall as a Border Bearded. I haven't grown it long enough to give it a rating yet.
