cymbidiums

Cymbidium, or cymbidiums, commonly known as boat orchids, is a genus in the orchid family (Orchidaceae), subtribe Cymbidiinae, comprising about 50–70 species native to Asia and Australia. They are evergreen plants that are typically epiphytic or lithophytic and are widely cultivated for their long-lasting inflorescences.

Plants have elongated pseudobulbs and straplike leaves. Flower stalks arise at the base and bear racemes of 6–20 flowers, usually 3–6 cm across. Flowers come in white, yellow, green, pink, and purple tones, often with markings; some species are fragrant.

In nature they occupy forests and rocky slopes from the Himalayas to Southeast Asia and northern Australia. In cultivation they prefer bright, indirect light, good air movement, and cool-to-intermediate temperatures; many hybrids tolerate warmer conditions, but cooler nights promote flowering.

Care and propagation: use coarse, well-drained media such as bark; water thoroughly when the medium dries but avoid waterlogging. Fertilize lightly during growth. Repot every 2–3 years. Propagation is by division; commercial production uses tissue culture.

Uses and significance: Cymbidiums are popular in horticulture for ornament and cut flowers; in East Asia they have cultural associations and are common in floral arrangements. Some species are protected in the wild; sustainable practices are advised.
