Grown at Wisley and propagated by us in celebration of the bicentenary Royal Horticultural Society.
Roscoea purpurea ‘Wisley Amethyst’ has beautiful orchid-like creamy white and purple flowers which appear from June through to August, and grows to a height of up to 40 cm. It was originally collected by plant hunter Frank Kingdon-Ward in 1938, and grown at Wisley and propagated in celebration of the bicentenary of the Royal Horticultural Society.
Roscoea are robust, herbaceous perennials in the ginger family. They are suitable for the front of borders, in a rock garden or grown in a container. With orchid-like flowers in the summer they can be found in colours ranging from white and cream through pinks, brick reds and purples. They have tuberous, fleshy roots (similar in appearance to dahlia) that become dormant in late autumn, with strap shaped leaves from April onwards. Some appearing above ground as late as June in the case of Roscoea ‘Red Gurkha’. They are hardy throughout the British Isles.
Roscoea grow well in light, dappled shade. They grow in any moist, free draining soil. They are frost hardy in the garden when planted at the right depth (10-15cm below surface). They can also be grown successfully in pots and containers where some frost protection is recommended during severe frosts.
