A good grower! But the color is more like the photos on the page, not as described in the text description above. Standards a reddish purple veined light purple to brighter violet. Falls light reddish purple, veined brownish red of the lighter outer haft. The beard is fine, sparse, yellow, and orange tipped at the base.

Lovely, old fashioned iris. Easy to grow. Found growing near the front steps when I moved into an old, no, ancient farmhouse. Loves to be cramped. Some of my best bloomers were jammed against the front steps. Blooms only last a few days depending on the heat, but it's a great old fashioned specimen. Blooms between late April and early May in Zone 7.
