From the north western United States comes this choice, evergreen ericaceous shrub that has clusters of attractive purple flowers in late spring and pale green leaves which are glaucous beneath. SOWING ADVICE: These seeds have already been cold-stored and should be sown on receipt onto a well-drained, peaty compost at any time of the year. The seeds should be just carefully watered in with no surface cover. The seed tray is best left in a cold or cool spot and kept moist, seeds often only germinating very slowly in cool conditions in the spring, regardless of when they are sown, although odd ones may come up at any time. Please be very patient. Plant out in peaty moist soil finally.
