About Many-Flowered Epidendrum

Epidendrum polyanthum · also called Many-Flowered Epidendrum · tropical

A reed-stemmed epiphytic orchid native to Mexico and Central America, the Many-Flowered Epidendrum earns its name from prolific multi-branched flower spikes bearing up to 20 small blooms per stem, primarily in summer. It is adaptable and relatively easy to grow in bright conditions with consistent moisture and feeding throughout the year, making it a rewarding choice for intermediate growers.

Preferred mix: Well-draining bark-based orchid mix or mounted on cork bark

Watch for — Root rot from poor drainage: Waterlogged bark medium causes the fibrous roots to blacken and collapse. Always use a freely draining mix in a pot with adequate holes, and check that the medium fully dries slightly between waterings rather than remaining saturated.
