Rhododendron Baden-Baden A dwarf cultivar, Rhododendron Baden Baden is a small evergreen shrub with a spreading habit, ideal for a small garden with acid soil. The deep-green, glossy, leathery leaves have pointed tips and are slightly twisted, giving the bush a lovely, mobile appearance. In April and May, masses of scarlet, trumpet-shaped flowers appear in clusters. Rhododendron Baden-Baden is compact enough to be grown in ericaceous compost in a big container. Dwarf rhododendrons dislike heat, so don’t plant near a warm wall. Benefits from a mulch of leaf-mould each spring.
