In Bloom at the National Botanic Gardens, Glasnevin

Cymbidiums are a genus of evergreen flowering plants in the orchid family Orchidaceae. They are epiphytic, lithophytic, terrestrial or rarely leafless saprophytic herbs usually with pseudobulbs. 

Most of the ancestors of today's cymbidiums originated from the forests of the Himalayas.

The genus Cymbidium was first formally described in 1799 by Olof Swartz. The genus name Cymbidium is derived from the Latin word cymba meaning "cup" "bowl" or "boat".

Generally flowering from mid autumn to Spring, they require a distinct temperature drop between day and night during mid- to late summer.

Requirements:

Good light levels all year round

Winter growing temperatures between 10-14°C, keep the temperatures below 30°C in summer

Moderate watering during spring and summer, do not allow the plant to sit in water and let the compost dry out a little before the next watering. Reduce watering to weekly or fortnightly in winter.

Use half-strength liquid fertiliser every third watering in spring and switch to a high potassium specialist orchid fertiliser in summer
