Thelymitra crinita, commonly known as the Blue Lady Orchid, is a tuberous perennial orchid native to the coastal and near-coastal scrub and woodlands of southwestern Western Australia. It typically grows to a height of 20-50 cm and features a single broad, lance-shaped leaf. From September to November, the Blue Lady Orchid produces up to fifteen strikingly brilliant blue flowers, each with a distinctive blue column and short yellow glands at the top. The flowers are known for their showiness and are a highlight when they open on sunny days, remaining closed during overcast weather.

The Blue Lady Orchid is valued for its vibrant blue flowers, which are a rarity among orchids and make it a sought-after species for native plant enthusiasts and orchid collectors. It requires well-drained soils and thrives in sandy or loamy substrates that mimic its natural coastal habitat. In cultivation, it should be grown in conditions that provide good air circulation and bright light but with protection from the hottest sun. While it is not commonly used in general horticulture, it is a gem for specialized native plant gardens and greenhouses. The main challenge in cultivation is replicating its specific soil and moisture requirements, as well as ensuring adequate dormancy in the off-season.CC BY-SA 4.0
