Landscape Uses:Container, Foundation, Ground cover, Massing, Rock garden, Woodland garden. Easily grown in a cool moist shady position[1, 187]. Requires an abundance of moisture in the air and soil[1]. Prefers an alkaline soil[200]. Requires an acid soil according to another report. A very ornamental plant[1], it does not always succeed outdoors in Britain[1]. It probably prefers to be covered in snow overwinter - could a mulch help[1]? This species is often divided into three separate species by botanists - the type species is found in eastern N. America, A. aleuticum is found in western N. America and a third species is found in eastern Asia[270]. Members of this genus are rarely if ever troubled by browsing deer[233]. Plants have a slowly-increasing rootstock[233]. Special Features:Attractive foliage, North American native, Naturalizing, Wetlands plant, There are no flowers or blooms. The plant is heat tolerant in zones 8 through 1. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is rhizomatous with underground stems sending roots and shoots along their length [1-2].
