Roscoea x beesiana
Roscoea
Origin: From the Himalayas and first collected by Francis Buchanan in Nepal the genus Roscoea was named in 1806 by the English botanist James E. Smith in honour of his friend William Roscoe the founder of the botanical garden in Liverpool, England. There are between, depending on source, some 18-22 species and based on recent phylogenetic analysis can be placed into two distinct groups; the Himalayan and Chinese. Roscoea x beesiana is a cross between R. humeana and R. cautleoides.

Description and Growing Information
Flowering Period
| Cultivation |
| Most species are considered hardy to USDA Zone 6 although not all species and cultivars have been proven so. Plant in a moist but well drained soil in partial to three quarters sun; full sun can lead to leaf scorch. Scree, rock gardens and pots are suitable placements. I overwinter plants in a dormant state in a cool room and force into bloom in the spring. After plants have bloomed, decrease watering towards the end of summer by laying the pot on its side in a cool greenhouse or cold frame. Once the foliage dies back, carefully remove it and store the potted, dormant plants in a cool, dry location until spring. |
| Growth |
| Medium |
| Leaf Description |
| Leaves with small "ears" at the junction of the blade and sheath and larger bracts, over rather than under 6 cm long. |
| Flower Description |
| The flowers are variable: most forms have a pale cream base colour with varying amounts of purple streaking, particularly on the lip or labellum. |
| Fruit Description |
| The fruit is a capsule with arilate seeds, which are black in colour. |
| Notable Specimens |
| The A.M. Cuddy Gardens, Strathroy, Ontario, Canada. |
| Propagation |
| Easy to germinate from seed the plants flower 2-3 years later. Division of mature clumps with care taken not to break or otherwise bruise the fleshy roots which can become entangled. |
