Iris lutescens campellii is a neat dwarf iris found in dry areas ranging from Italy to southern Spain. It has small lavender flowers with a darker purple signal and beards that are white with some yellow. Foliage is typical blue-green iris foliage that is slightly curved. Because of its small size (4-6" in my garden), it makes an excellent addition to the rock garden or trough garden.
It can also be used in a mixed perennial border as long as care is taken to make sure it isn't over crowded by other plants. Make sure it has well drained soil, as like most bearded iris it doesn't like excess water. While drought tolerant, it doesn't want to be too dry either, and will perform best with some irrigation and fertilizer in the summer months.
