Bold orchid-like rich purple flowers. It has lots of vigour and is clump forming. Flowers: May and June Height: 15-20cm
Large flowering-sized tuber (similar to dahlia in appearance).
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. 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.
Water well after planting and as the plant establishes. Ensure that they don’t suffer from drought in the summer or waterlogging in the winter.
