Hachmann's Rokoko is another beauty from the collection of dwarf or low growing Japanese azaleas bred by German rhodo/azalea guru Hans Hachmann. It produces medium large, about 5 cm across, semi-double flowers of rich pink colour. They open from mid May until early June on the background of small, dark green, ovate to elliptic, and very glossy leaves. They are reliably evergreen. The plant grows low and wide, forming dense cushions. Japanese azaleas can be clipped to shapes in early June. If so, do not use fertilizers enhancing growth rate. The size of new branches would get out hand and spoil the shape you are going to achieve. They need light, permeable soil that is acid, constantly moist (keep azaleas mulched at all times) and moderately fertile. Use fertilizers for rhododendrons and azaleas, or ericaceous plants. They are fully hardy to about -25°C.
