From the standards, to the falls, to the beard between, this iris is dressed in the most unusual hue. And because Java Blue is so well branched, it'll produce up to 10 buds per stem. Let it grow in floriferous groups for a sea of indigo. It'll also perform for years in a perennial mixed border, or you could design a unique color palette around it in a container garden. Java Blue grows easily and quickly in any well-drained soil, and butterflies love its spicy scent. Iris germanica 'Java Blue'
