Like the red playing card soldiers from Alice in Wonderland, the scarlet flowers of Disa uniflora ‘Red River’ marched across Dave Parkinson’s incredible exhibit at Hampton Court last week. They were joined by an army of other disas in dayglo shades of pink, yellow and orange, fighting with one another for floral supremacy. These fascinating little orchids are from Table Mountain in South Africa, where they grow near streams and springs with their roots in the water. What they lack in stature they certainly make up for in sheer flower power. Marvellous!
