About Dragon fruit
Selenicereus triangularis, also known as the spotted flower pitaya, is an epiphytic cactus with triangular, climbing stems that produce large, white, fragrant nocturnal flowers. Its bright green stems can reach several meters in length, either hanging or climbing on supports. It is ideal for hanging baskets, pergolas, or as an indoor plant if given proper support.
Native range
Mexico and Central America
Care tips
It requires bright, indirect light; avoid strong direct sunlight, especially during midday, as it can scorch its stems. Water thoroughly when the substrate feels dry to the touch, reducing frequency in winter to prevent root rot. Use a well-draining substrate, specific for epiphytic cacti or a mix with perlite and orchid bark. A common mistake is overwatering, which can lead to stem and root rot.
