Azalea 'Coral Bells'

Rhododendron indicum (roh-do-DEN-dron IN-dih-kum)

Family: Ericaceae Unknown Shrub (3-15 ft)

with showy pink flowers that appear in the spring. It grows at a medium pace to a height of 2 to 6 feet tall and a width of 3 to 6 feet. Plant in a location where it will receive partial shade and where you can provide regular watering. The showy pink flowers are abundant even on newly planted shrubs. This plant works well in a shrub border, in a woodland garden, or planted in containers on a patio. This cultivar is highly susceptible to Phytophthora root rot, so practice good cultural conditions where you plant. 'Coral Bells' is a dwarf evergreen cultivar of the Kurume Azaleas semi-evergreen shrubs in the Ericaceae (blueberry) family. This compact azalea has a mature size of about 2 to 6 feet tall and 2 to 3 feet in width. While it has a dense canopy it can spread. The genus name, Rhododendron, derives from the Greek words rhodo , which means rose, and dendron , meaning tree. This plant prefers partial shade and acicic well drained soil that is moist and high in organic material. It is intolerant of heavy and wet soils, drought, and excessive fertilization. It has a slow growth rate and requires a high level of maintenance including removing spent flower clusters immediately after flowering. 'Coral Bells' has showy, coral pink flowers that bloom in mid to late spring and occasionally again in the fall. It works well in the landscape as an understory shrub mass planted or in small groups in woodland or naturalized areas, or as specimens in pollinator gardens where the flowers will attract bees. It can also be used as a low hedge or in a winter garden where its leaves turn attractive shades of red. Quick ID Hints: Small shrub, sympodial growth, with crowded evergreen leaves in tiers Twigs & leaves covered with reddish-brown hairs Flowers axillary, single in spring with funnel-form corolla Calyx 5-lobed, elongated & pointed Insects, Diseases, and Other Plant Problems: Insect problems include aphids, borers, lace bugs, leafhoppers, mealybugs, mites, nematodes, scale, thrips, and whitefly. Diseases include canker, crown rot, root rot, leaf spot, rust, and powdery mildew. While these shrubs remain very popular for landscape use, many cultivars are susceptible to Phytophthora root rot—this leads to leaf loss, reduced vigor, branch dieback, and wilting. Implement good cultural practices first, such as improving drainage with organic matter or berms and avoiding overwatering or overfertilization. However, if you have a site with a history of this disease, consider planting one of the root rot-resistant alternative species listed in the left-hand sidebar. For suitable alternatives, see this video created by Charlotte Glen as part of the Plants, Pests, and Pathogens series.
