Polygala × dalmaisiana |
Growing to 1.5 m (4.9 ft), it is a tender evergreen shrub with pea-like purple flowers in late summer. As it does not tolerate temperatures below 5 °C (41 °F), in temperate zones it must be grown under glass. However it may be placed outside in a sheltered spot during the summer months.[2] It is a recipient of the Royal Horticultural Society's Award of Garden Merit. [2]
