Rhododendron 'Rosebud'

Rhododendron ‘Rosebud’

The name of this plant is very fitting. Taken out of context, the 2″ flowers look very much like a miniature pink rose. This dwarf evergreen can get to be 2′ to 3′ tall and wide, although some sites claim that it can get larger than this. It blooms later than most Azalea, late May and early June for us.

Rhododendron is native to Japan.

Cultivation Notes

Best grown in acidic, organically rich, moisture-retentive but well-drained soils in part shade. The more sun they can get while their moisture requirements are met will lead to more blooms.

Rhododendrons and Azaleas are susceptible to many insect and disease problems. Insect pests include aphids, borers, lacebugs, caterpillars, leafhoppers, mealybugs, nematodes, scale, thrips and whitefly. Mites may also appear. Disease pests include blights, canker, crown rot, leaf gall, root rot, leaf spot, rust and powdery mildew.

Additional Information

This is a hybrid variety developed from Kurume azaleas, that are themselves hybrids of R. kiusianum and R. kaempferi, native to the volcanic slopes of Northern Japan. It is a Joseph Gable, of Stewartstown, Pennsylvania, hybrid. Rosebud was a cross between ‘Louise Gable’ and ‘Caroline Gable,’ both of which were hybrids of R. poukhanense, the Korean Azalea and R. kaempferi. Rhododendrons have 10 stamens in a flower and Azaleas have only 5.
