Rhododendron ferrugineum Alpenrose Evergreen shrub (1 Page of 5) The Rhododendron ferrugineum plant species is found in Europe. It is a member of the Ericaceae family. Common gardeners may know the plant as Alpenrose. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Rhododendron ferrugineum Common Name: Alpenrose Family: Ericaceae Author: L. Known Hazards: The leaves and the galls are poisonous[61]. The pollen of many if not all species of rhododendrons is also probably toxic, being said to cause intoxication when eaten in large quantities[183]. Mature Height: 1.5 Mature Width: Habitat: Mountain slopes in open woods or scrub, often dominant in the dwarf shrub zone[50].
Cultivation Notes: Succeeds in a most humus-rich lime-free soils except those of a dry arid nature or those that are heavy or clayey[1]. Prefers a peaty or well-drained sandy loam[1]. Succeeds in sun or shade, the warmer the climate the more shade a plant requires[200]. A pH between 4.5 and 5.5 is ideal[1].
This species grows better in the midlands and north Britain, disliking the hotter conditions in the south[11].
Succeeds in a woodland though, because of its surface-rooting habit[200], it does not compete well with surface-rooting trees[1]. Plants need to be kept well weeded, they dislike other plants growing over or into their root system, in particular they grow badly with ground cover plants, herbaceous plants and heathers[200].
Plants form a root ball and are very tolerant of being transplanted, even when quite large, so long as the root ball is kept intact[200].
Plants in this genus are notably susceptible to honey fungus[200].
