Strophocactus wittii is a native to South America, creeping epiphyte that grows up tree trunks. The leaf-like stems, called phylloclades, are pressed against these trunks and support aerial roots along their midribs. These plants thrive in full sun to semi-shade positions, and need regular watering. Although the plants produce small leaves with thorns or spines, the blooms are its main draw. White or off-white flowers, measuring around 2 inches across, with notched petal edges, only open for one night - hence its nickname, the Amazon Moonflower!
When grown in its proper hardiness zone (USDA Zone 9-11), Strophocactus wittii can be planted in potting soil that is enriched with organic matter, and well-drained. In the warmer months, water regularly and in the winter, water can be reduced to occasional. For colder regions below USDA Zone 9, Strophocactus wittii can be grown in a pot and brought inside during the colder months. Keep its environment humidity, bright, indirect and/or partial light, and a stable temperature to help it successfully overwinter.
Overall, the Strophocactus wittii is a stunning addition to gardens. With proper care and effort, it may produce lush foliage and fragrant blooms. Its pot will mean regular repotting is required, but the effort is worth it for this majestic species. It can grow to a height of up to 20 ft, depending on how well it is cared for.
