Calanthe tricarinata (Hardy Calanthe Orchid)

Calanthe tricarinata, known as the Hardy Calanthe Orchid, emerges as an enchanting evergreen to semi-evergreen terrestrial orchid. Its distinctive elegance comes to life through racemes of nodding flowers, each adorned with exquisite yellow-green tepals and a reddish-brown lower lip. This floral symphony graces gardens from late winter to early spring, with the blooms rising on erect stems above a backdrop of elliptic to lance-shaped, ribbed, mid-green leaves. The foliage tends to retain its evergreen splendor in milder climates but may enter dormancy in colder regions. Originating from a pseudobulb, the Hardy Calanthe Orchid gradually forms a captivating clump over time, naturalizing and spreading modestly through bulb offsets. Its allure is equally captivating whether showcased in pots, containers, beds, or borders, rendering it an exceptional choice for shade garden settings and woodland landscapes.
