Native to the Himalayas, this large, spreading shrub bears splendid plumes of creamy-white fragrant flowers in early summer. Sometimes called false or tree spiraea, this is a close relative of the more familiar garden spiraeas. The Royal Horticultural Society has given it their prestigious Award of Garden Merit (AGM).
Seeds have already been thoroughly cleaned and cold-stored for several months. Sow into well-drained, sandy compost at any time of year, cover to their own depth with sand or grit. No artificial heat is needed; seed tray is best left in a cool protected spot and kept moist. Seeds usually germinate in spring, regardless of when sown.
