Given lime free or neutral soil, this is a sterling long lived plant for either sun or shade. In the species L., the plants grow into quite hefty tufts, with abundant evergreen bladed of dark shiny green, to about 15 inches high and just above nestle small spikes of bright blue in late summer and autumn. Individual flowers are small,- reminiscent as the specific name denotes, of the ‘Grape ’. The are a mass of fibre plus storage nodules and plants can withstand drought, flowering best in sunny conditions. L. ‘Majestic’ will not flower except in a very sunny place. It is dwarfer and broader leaved, but flowers are larger in a deep lavender blue. Both can be divided in spring, and being slow to recover, should be left alone as long as possible. L. is a subject of such adaptability and usefulness that is should be more widely grown.
