A sub shrub, one that continues to increase in woody growth until a severe winter cuts it to the ground like an herbaceous plant.
The growth habit of Nipponanthemum nipponicum suits this description. The specimen in the rock garden has two or three years growth covered in glossy green leaves and topped with white floretted Nipponanthemum nipponicumflowers. A magnificent addition to the garden at this time of year. If allowed to get too old the growth becomes leggy and flops apart exposing an open centre. Ideally cultivate in full sun for maximum flower production.
