In the garden

Cypripedium tibeticum is a slipper orchid from the montane regions of Bhutan, Sikkim and western China. As a species used to cool, shaded sites, it performs best where bright sun is filtered and the soil contains plenty of organic matter to hold moisture without becoming waterlogged. Flowering takes place from May to July. For cultivation, provide a position of partial shade and a humus-rich, well-drained substrate with neutral to slightly acidic pH. Keep the root zone consistently moist rather than letting it dry out between waterings; at the same time ensure excess water can drain away so the crown does not sit in stagnant wet soil. Avoid heavy, compacted soils by incorporating leaf mould or well-rotted compost to improve structure and water-holding capacity. In the UK, site Cypripedium tibeticum at the edge of a shaded border, beneath deciduous trees or alongside a sheltered woodland path where light is dappled. Mulch with coarse leaf mould to maintain moisture and protect roots through cool periods. Expect the plant to come into bloom between May and July.
