Dendrobium sulcatum

Dendrobium sulcatum is a distinctive deciduous orchid recognized by its flattened, deeply grooved canes and cheerful golden-yellow flowers. The clustered blooms, often accented by warmer tones at the lip, create a bright spring display on mature growths with unmistakable botanical character.

Care Guide

• Light: Provide bright, filtered light, with gentle morning sun if available. Good light helps mature the canes and supports flowering.
• Water: Water generously while new growth and roots are developing, allowing the medium to approach dryness between waterings. After the canes mature and leaves begin to fall, reduce watering for a cooler, drier rest.
• Humidity: Maintain moderate to high humidity with good air circulation throughout the year.
• Temperature: Grow in intermediate conditions during active growth, followed by cooler nights as the canes mature.
• Growing medium: Use a coarse, fast-draining orchid mix that keeps the roots well aerated. Repot when new roots begin to emerge.

With vigorous seasonal growth followed by a cool, drier rest, Dendrobium sulcatum can reward the grower with clusters of brilliant yellow flowers on its uniquely sculpted canes.
