Rhipsalis teres f. prismatica – Growth and Care Essentials


Rhipsalis teres f. prismatica, formerly classified as Hariota prismatica Lem., is a striking epiphytic cactus native to the tropical rainforests of Central and South America. This species is known for its long, prismatic (three-angled) stems, which trail beautifully in hanging planters. Unlike desert cacti, it flourishes in shaded, humid environments, making it well-suited for indoor cultivation. When mature, it produces small, white to pale pink flowers, followed by translucent or white berry-like fruits.
