Description
R. canescens, also known as piedmont azalea and wild azalea [1], is a perennial shrub of the Ericaceae family native to North America. [2] It is a shrub that reaches a height of 5 meters tall, with 5 stamens that are approximately 3 times longer than the corolla tubes. [3]
Distribution
R. canescens is found in the southeastern corner of the United States from Texas to Pennsylvania with the exception of Virginia and West Virginia. [2]
Ecology
Habitat
R. canescens proliferates in swamps, pocosins, and savannas. [1] It has been observed in various habitats including sandy loam in mesic woods, magnolia-beech ravines, pine flatwoods, shrubs of bayheads, bottomland woodlands, deciduous wooded bluffs, wet streamsides, bank on shores, under shade of various hardwood forests, swampy woodlands, and near border of sand dune community. [4] R. canescens responds negatively to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[5]
Phenology
R. canescens has been observed to flower February through April [6], as well as in May, June, and November. Fruit development has been observed in February, March, April, June, and September. [4]
Fire ecology
R. canescens is not fire resistant and has low fire tolerance. [2]
Conservation and Management
R. canescens is listed as commercially exploited by the Florida Department of Agriculture & Consumer Services Division of Plant Industry, and as endangered by the Kentucky State Nature Preserves Commission. [2]
