Clusters of ivory-white, fragrant flowers, very similar in appearance to those of the Lily of the Valley, are grouped in terminal panicles, and bloom in early to mid summer at a time when most other trees and shrubs are long finished. This lovely and rarely-seen evergreen tree comes from the Azores and Madeira. It does best in a sheltered spot.
Height: 4 m.
Hardy in: zones 7-10 (-5 C)
Sowing instructions: should be sown into a well-drained, sandy compost at any time of the year, and covered thinly with sand or grit and kept moist. Keep at between 15 and 20 degrees C. Germination usually occurs within 4 to 6 weeks although some seeds may take much longer.
Planting instructions: It is adaptable but does best in a cool, moist climate and a lime free soil.
