About Brigham's Specklinia

Specklinia brighamii · also called Brigham's Specklinia · tropical

A miniature warm-to-hot epiphytic orchid native to Belize and Guatemala, growing in humid lowland and foothill forests. It forms compact leafy clumps and produces successive small flowers throughout the year. Mount on bark or grow in a coarse, well-drained mix with consistent moisture and excellent air movement.

Preferred mix: Coarse bark and perlite, or cork/tree-fern mount with sphagnum

Watch for — Root death from medium breakdown: In warm, humid conditions the bark medium decomposes rapidly, retaining excess water and suffocating roots. Repot every 18–24 months; inspect roots when the plant shows reduced vigour or water drains slowly.
