About Yellow pitahaya
Selenicereus megalanthus, also known as yellow pitaya or yellow dragon fruit, is an epiphytic or lithophytic cactus with long, triangular stems that produces edible fruits with yellow skin and white pulp containing black seeds. Its nocturnal flowers are large and fragrant. It is ideal for hanging baskets or as a climbing plant with support, adding an exotic touch to warm patios and gardens.
Native range
Northern South America (Colombia, Ecuador, Peru)
Care tips
It requires bright light, preferably morning direct sun or filtered sun, avoiding intense midday sun exposure. Watering should be regular during growth, allowing the substrate to dry slightly between waterings, and reduced in winter. Use a well-draining substrate, rich in organic matter, similar to that used for orchids or epiphytic cacti. Avoid waterlogging, as it is susceptible to root rot.
