Percherons are a French draft horse breed which makes me want to grow this one for the name alone (drafts are an obsession of mine). My assumption is that the name refers to the dappled coat of the grey Percherons.

This is the best siberian iris in my garden. The flowers are large with good substance and hold their color well. Each flower lasts several days. Highly recommended
