Dendrobium kingianum (Pink Rock Orchid)

Pink Rock Orchid


Dendrobium kingianum (Pink Rock Orchid) is usually a lithophyte but is occasionally an epiphytic or rarely a terrestrial orchid. In late winter to mid spring, it boasts charming racemes, 6 in. long (15 cm), of up to 15 sweet-scented, pink, purple or white flowers, up to 1.5 in. across (4 cm), adorned with a crimson or purple veined or blotched lip. The delicate flowers last about 2 weeks. They are borne on erect stems bearing between 3 and 6 thin, green and smooth, evergreen leaves near their tips. Native to eastern Australia, Dendrobium kingianum can be found growing on boulders and in rock crevices in open forest or adjacent to forest creeks, or on cliff faces. Dendrobium nobile is popular in Australian species orchid cultivation and is relatively easy to grow. Like many Australian native plants, it is illegal to collect specimens growing in the wild.

Tip for reblooming

  • If a plant is healthy but does not produce flowers in a reasonable time, then increase the light, and your orchid should get back on track blooming regularly.
