One of the well-known Knaphill hybrid azaleas, Rhododendron Harvest Moon is a medium-sized, deciduous shrub of only moderate vigour with a shapely, upright, rounded habit. The leaves are grey-green, colouring well in autumn. In May, the shrub carries really beautiful, soft yellow flowers with a deeper chrome yellow to orange blotch and golden anthers; the flowers are lightly scented. Azalea Harvest Moon needs a fairly sunny position. Dead-head carefully (next year’s buds are just below this year’s flowers) to promote growth instead of seed production. Can be grown in soil-based ericaceous compost in a large container, using rain-water and ericaceous slow-release fertiliser.
