The early blue-mauve flowers of this species make a brilliant addition to the late winter/early spring garden. Best in a warm, sheltered, well-drained, sunny spot against the house wall and out of the rain where you'll ignore it -- it hates to be fussed over. Forms a good clump of evergreen spiked foliage that looks best in fall and winter. Hails form the Mediterranean. Fragrant.
