About Hedgehog-Lip Bulbophyllum

Bulbophyllum echinolabium · also called Hedgehog-Lip Bulbophyllum, Hedgehog-Shaped Lip Bulbophyllum · tropical

Bulbophyllum echinolabium is a warm-growing epiphyte from Sulawesi noted for producing possibly the largest flowers in the entire genus — inflorescences to 70 cm with individual blooms to 35 cm long. The distinctive lip is covered in spiny projections resembling a hedgehog. It requires high humidity, warm temperatures, and consistently moist but free-draining bark or mounted culture.

Preferred mix: Open bark mix with sphagnum moss; or mounted on cork with sphagnum pad

Watch for — Pseudobulb shrivelling: Wrinkled pseudobulbs indicate underwatering or poor root function. Check that roots have not rotted from a previous wet episode. If roots are healthy, increase watering frequency; if roots are damaged, trim, treat with cinnamon powder, and repot into fresh medium.
