Epidendrum porpax var. alba 'Tiny Green'

This cute species is a compact, mat-forming miniature native to Colombia and Venezuela. It blooms with bright greenish-yellow flowers.

It's often grown mounted on slabs due to its creeping habit, but will quickly fill a pot. They thrive in intermediate-to-warm conditions with high humidity, frequent watering, and bright, indirect light. It's free flowering throughout the year and flowers often!

These are blooming size plants in 2" pots.
