Calanthe tricarinata (Hardy Calanthe Orchid) is an evergreen to semi-evergreen terrestrial orchid boasting racemes of with exquisite nodding flowers adorned with yellow-green tepals and reddish-brown lower lips. Blooming in late winter to early spring, they are borne on erect stems above the foliage of elliptic to lance-shaped, ribbed, mid-green leaves. The foliage is evergreen in milder climates, but can go dormant in colder areas. Arising from a pseudobulb, Hardy Calanthe Orchid will naturalize and spread modestly by bulb offsets, forming a charming clump over time.

  • Calanthe Orchids can withstand a minimum temperature of 14°F (-10°C). It is advisable, in regions with severe winters, to protect them during long periods of freezing. Mulch with composted bark over winter.
  • A lovely addition to beds and borders, woodland gardens, or containers.
  • Virtually disease free. Keep an eye out for slugs and snails.
  • Propagate by division of pseudobulbs in spring.
