About Maxillaria picta

Maxillaria picta · also called Painted Maxillaria · tropical

Maxillaria picta is a rewarding, easy-growing Brazilian epiphyte producing a flush of fragrant, yellow flowers spotted and barred with maroon, often in winter. With clustered pseudobulbs and grassy foliage, it handles intermediate conditions, bright shade, high humidity and a seasonal rhythm. One of the more tolerant and floriferous Maxillarias, it suits pots, baskets or mounts for a beginner-friendly species orchid.

Preferred mix: Medium epiphyte mix in a pot or basket

Watch for — Root rot from stale medium: Broken-down, soggy mix suffocates the roots. Use an open medium, water with good drainage, and repot before the mix decomposes.
