Vancouveria Hexandra. Known as the "inside-out flower". A dainty North American woodlander. A clump forming perennial with white flowers with reflexed petals (hence the name inside out flower) are held above the foliage in spring to summer. Vancouver hexandra spreads by underground rhizomes and will form a nice clump which can be divided in early spring if clumps become too large, or to help establish a larger colony however it is easy to control. Fertilise with a liquid seaweed fertilizer in spring. Can reach a height of around 35 to 45 cm, Vancouver hexandra is closely related to Epimedium species and grows well in similar woodland conditions. An excellent companion for Dicentra species.
