Roscoea purpurea 'Ant Marian' - 2026

Roscoea purpurea ‘Ant Marian’ is a tuberous perennial noted for its large violet-purple, orchid-like flowers that bloom in summer, adding a splash of bold colour to shaded borders or woodland gardens. The flowers are borne above mop-like clumps of lance-shaped green leaves, giving both vertical interest and lush texture. This cultivar thrives in humus-rich soil and areas with partial shade, where the blooms can be appreciated without scorching from intense sun. Its ease of growth and remarkable flower size make it a standout among Roscoea varieties.

It thrives in partial shade, preferring moist but well-drained, humus-rich soil. Low-maintenance once established, it benefits from protection from harsh frost in early growth stages. Non-native to the UK, it is celebrated for its exotic appearance and ability to bring tropical-style blooms to temperate gardens.
