Name: Dendrobium bigibbum Lindl. ‘Variegated’
Synonyms: Durabaculum bigibbum (Lindl.) M.A.Clem. & D.L.Jones
Etymology: The genus name Dendrobium derives from the Greek words dendron (“tree”) and bios (“life”), referring to the epiphytic lifestyle of many species. The specific epithet bigibbum roughly means “two-humped.” ‘Variegated’ refers to the variegated cultivated form.
First described: In 1852 by John Lindley.
Origin/Distribution: Northern Australia and southern New Guinea.
Habitat: Epiphytic or lithophytic in warm tropical habitats with a seasonally drier period. We grow this species in very bright light at around 18–30 °C with good air circulation. Water and fertilize regularly during active growth; after the canes have matured, watering can be reduced slightly.
Description and notes: Dendrobium bigibbum produces upright, sturdy canes with firm leaves and striking flower spikes. The cultivated form offered here also has decoratively variegated foliage. The flowers typically appear in shades of pink to purple. We use a coarse, very airy orchid mix and avoid keeping the roots wet for extended periods.
