Blue-eyed grass

A meadow dotted with clumps of this plant, often called blue-eyed grass, is a lovely sight. Where it is hardy, 'Aunt May' has earned its place in more formal settings. Its erect iris-like foliage striped with cream brings a vertical dimension to the border and contrasts with its mostly mounded neighbors. Poor to average soil is suitable for most types; blue-eyed grass thrives in damper conditions, where it self-seeds freely.
