Crenate Orchid Cactus

Epiphyllum crenatum | Rating: 0 votes | Print / Pdf

Commonly used in creating hybrids, the significance of epiphyllum crenatum to gardeners is pretty high. Known as the crenate orchid cactus, it grows erect with broadly toothed, flat grey-green principal stems that eventually become woody in texture. It also has smaller, secondary stems that are flat and succulent and leaves that are long and linear. It flowers in spring, with large, fragrant, trumpet-shaped white flowers emerging at night only, but remaining open for several days. The crenate orchid cactus requires warmth and humidity, so growing under glass is best. Pot in cactus compost with ample moisture, and bright but filtered light. No pruning is necessary but re-pot every two years.
