Questions people ask

Why are my stems turning red?

This is often a stress response to too much direct sunlight.

Does it need a dormant period?

Yes, it benefits from cooler nights and drier soil in late autumn to set buds.

Where the name comes from

The genus honors the French cactus collector Frédéric Schlumberger, while the species name commemorates John Russell, 6th Duke of Bedford, in whose collection the plant first flowered.

Good to know

• It is an epiphyte that grows on trees in the wild.
• The flowers are zygomorphic, meaning they have bilateral symmetry.
• It requires cooler temperatures and shorter days to trigger blooming.
