These hybrid azaleas come from New Jersey, USA, and were developed by Robert Gartrell. The aim was to select and further breed cultivars with the best performace, extending their flowering period and keeping majority of leaves in winter months.
Description of the plant:
Dorothy Hayden has large, pure white, funnel-shape flowers that open from end May until late June. They pop up continuously unlike early Japanese azaleas that cover the whole plant with a mass of flowers. It grows slowly making a compact, low shrub does not need to be pruned. Evergreen leaves are mid green, ovate, medium-small. In semi-shade and shade they are evergreen, but still less sensitive to sun than other Japanese azaleas.
Japanese azaleas can be clipped to shapes in early June. If so, do not use fertilizers enhancing growth rate. The size of new branches would get out hand and spoil the shape you are going to achieve. They need light, permeable soil that is acid, constantly moist (keep azaleas mulched at all times) and moderately fertile. Use fertilizers for rhododendrons and azaleas, or ericaceous plants. The best soil mix is 1/3 of peat, 1/3 of leaf-mould or lime-free compost, and 1/3 of soil from the hole where you are going to plant it. Azaleas have shallow roots, so do not plant them too deep. They are fully hardy to about -24°C (USDA zone 6).
