Cypripedium macranthos, commonly known as the Large-Flowered Cypripedium or Big-Pouch Lady’s Slipper, is a perennial herbaceous orchid native to temperate deciduous forests, forest margins, and damp grasslands in Belarus, Russia, Mongolia, Japan, Korea, and China. It typically grows to a height of 12-24 inches (30-60 cm). The orchid is notable for its striking blooms, which appear in late spring to early summer. The flowers are large and showy, with a distinctive inflated pouch that is usually pink, white, or purple, and a dorsal sepal and petals that are often spotted or mottled with maroon or purple.

The Large-Flowered Cypripedium is valued for its ornamental flowers and is often cultivated in shade gardens and woodland settings. It requires moist, well-drained soil rich in organic matter and thrives in part shade to full shade conditions. While it can be a challenge to grow, success is more likely when its specific soil and moisture needs are met. This orchid is not typically prone to serious diseases or pests, but it can suffer from root rot if overwatered or planted in poorly drained soils. It is also important to note that Cypripedium species are subject to over-collection in the wild and should be sourced responsibly from reputable nurseries.CC BY-SA 4.0
