Salvia verticillata ‘Purple Rain’
Purple Rain Salvia
Large leaves and long wands of slightly arching purple flower stems covered in purple flowers attracting hummingbirds and butterflies. Really lovely! Purple Rain is a variety with a shorter more compact growth habit. This salvia loves lean soils growing well even in cracks, crevices and other shallow soil conditions. Rich soils and low light may cause flopping. Full sun. Good drainage. Height and spread 24″. Zones 5-8
