Epiphyllum hookeri (Climbing Cactus)

Epiphyllum hookeri is a small shrub native to Central America. It is an epiphytic cactus, meaning its stems cling to other plants for support and can grow as tall as 20 feet. The plant produces large, white or off-white flowers that measure about 8 inches wide and open at night. Additionally, the stigma of the flower has a bright red color with a yellow, star-shaped tip.

Epiphyllum hookeri can be grown in USDA Zone 9-11, given the right treatment and conditions. The ideal location is in semi-shade and with moist, not overly wet soil. During the growing season, some additional water may be necessary. For indoor care, the plant should be placed in a bright, light spot but kept away from direct sunlight. The soil should be watered regularly, but not allowed to dry out completely.

In regions with colder winters, Epiphyllum hookeri should be protected from frosty temperatures. Outdoor plants can be moved into an area such as a greenhouse or protected with an insulating layer of mulch. When grown in a container, the pot should be placed in an area with indirect sunlight and protected from temperatures below 50F. Water the plant whenever the soil begins to dry, and apply a balanced, slow-release fertilizer in the springtime. During its dormant period in winter, reduce watering, misting and fertilizing.

Epiphyllum hookeri is also well-suited for terrariums, as long as it receives semi-shady, humid conditions and regularly misted, mimicking its natural habitat. With proper winter protection, the plant can survive for many years in colder climates.
