Helen Collingwood [Extravaganza x Louise Blake] 1949 TB 40" scapes ML Season Bloomtime. Beautiful Dark Violet Purple Falls under the Palest Light Lavender Sky Blue White Standards on the top. The first time I saw Helen Collingwood's picture, I didnt like her, but she is so stunning in person and so unique, the Blooms are just huge, and the color contrast of these almost White Blue Standards with this Deep Purple is one of a kind. My son bought me this variety for my birthday. In my opinion, it's one of the most beautiful 2-Tone Bi-Color Historic Neglectas' of all time.

This is a tough girl! It is one of the survivors who was left unattended in a pallet of sand at my old home site when my house was literally picked up and moved. I have had no means to move them or place to plant them until now. She is still blooming strong after 2 years of total neglect in a pallet of sand. Beautiful velvety color and nice 2-tone contrast.

Award of Merit, 1952.
The 1976 Schreiner's catalog, pages 26 & 68, describes this as a vivid bicolor with light lavender standards and deep plum purple falls.
These colors were accurately captured in my 2008 photograph, but the scanned image of it shows the standards with a blue cast. The beards are yellow.

Well, this is where it all started for me. My father grew only 2 variaties of irises and this was one of them. It was the first iris I ever grew, and I still grow it today along with 300+ other varieties. It is one "tuff lady". It always blooms prolificly, no matter the condition. If you look at the picture I imported to this site, you will notice that it is growing in a dense patch of weeds. This is not the main clump in my iris bed, but where it once was and I moved it. But evidently I left a piece behind in this area that is no longer cultivated. Lo and behold a new clump was born on its own! You can't go wrong with this one!
