Dendrobium nobile, the Noble Dendrobium, is a popular cane-type orchid that produces clusters of fragrant, showy flowers in white, pink and purple with a contrasting dark throat, borne along its tall, jointed pseudobulbs. Widely grown across India and Southeast Asia, it is more sun-tolerant than the Moth Orchid and adapts well to bright balconies and windowsills. The blooms are long-lasting and richly coloured. Grown in chunky bark, it appreciates a distinct cooler, drier winter rest to set buds, after which it bursts into a spectacular spring display.

Growing tips
In India give it bright light with gentle morning sun and, crucially, a cooler and drier rest from late autumn (stop feeding, water sparingly) to trigger heavy flowering in spring; do not mistake the leafless winter canes for a dead plant.
