Purple moor grass: Molinia caerula
This genus of perennial grasses only has two species that grow on heath and moorland in Europe and Asia. Its gold brown autumn colours and elegant habit make it a very decorative container plant for balconies and terraces.
Purple moor grass forms mounds of slender, upright leaves 50 cm (20 in) long. The violet-coloured flowers borne in slender panicles are produced from spring until autumn. In contrast to the species, which can reach a height of 1.5 m (5 ft), the white-striped ‘Variegata’ variety only grows 60 cm (24 in) high. The ‘Moorhexe’ variety that has dark purple panicles is also a very good choice.
This hardy grass grows best in acidicthat must be kept moist at all times in full sun or partial shade. It combines very well with heathers. It can be raised from seed or propagated by division. Plants raised from seed do not come true to type.
