Gardeners' Notes:

Positive LauraSteele On May 29, 2011, LauraSteele from Fort Wayne, IN wrote:

Nice tall plant. Delicate color and bloom form. Lots of buds per stems. Stood up well to the 3 hail storms we had last week. Increases at a nice rate, too. Would recommend for the back of the border given it's height.

This beautiful iris was the first bearded iris to bloom in the garden this year. I also love the starkness of such a tall bloom stalk on what is not a very tall clump of leaves. All in all, it is a distinctive iris.

Neutral Joan On Jul 10, 2005, Joan from Belfield, ND (Zone 4a) wrote:

A historic iris from 1844. One of the oldest plicatas still grown.

This 150 year old iris cultivar has clean white petals stitched with blue-violet plicata markings. There are 7-8 flowers produced per stem. The best way to describe this historic iris is "long".
