General Description

Robin Hill hybrid azaleas are a large group of evergreen shrubs that were hybridized in New Jersey by chemist and rhododendron enthusiast, Robert Gartrell. They are complex hybrids which combine the attributes of small-flowered hardy azaleas with those of the more tender large-flowered types. Generally, they are compact, spreading or mounding, have an extended blooming season and bear large flowers on small plants.

This large group of azaleas is quite cold tolerant. Their leaves are generally bright green, broadly elliptical to oval and hairy. Very large funnel-shaped blossoms are produced late in the spring and may be single, double, semi-double or hose-in-hose (two sets of petals, one inside the other). The flowers are borne singly or in clusters at or near the ends of the branches and come in a wide range of colors.

Azaleas prefer sites with partial shade and highly organic, acid soil that is evenly moist but well-drained. Plant them shallowly and mulch well to conserve moisture and suppress weeds. They prefer locations with warm summers, cool winters and do require some winter cold for good growth. The flower buds develop in summer for the following springs display, so prune shortly after flowering, if necessary. All azaleas look their best when mature size is considered when placing in the landscape to avoid the necessity of constant pruning.

Robin Hill azaleas are great for shaded woodland gardens, foundations, hedges, accent plant, Japanese gardens, containers and bonsai.
