This variety is an EXTREMELY rampant grower for me. It generated seven bloom stalks the first spring after planting! Do not plant next to slow increasing varieties- she will swallow them up.

Good grower here. It's one of those irises you either love, or hate the coloring. It takes on different hues depending on the climate (kind of like "Thornbird" does) Gets noticed!

S. light grey (lighter than RHS 197D); style arms light grey; F. light brown grey (lighter than 199D), washed brown purple hafts; beards bronze, base purple; ruffled.
