About Hoya
Hoya subcalva is an epiphytic vine from the Apocynaceae family, native to the rainforests of Papua New Guinea. It is distinguished by its large, oval, glossy leaves and clusters of pale pink to cream waxy flowers with a delicate citrus scent. It's an excellent choice for hanging baskets or for growing on a trellis in bright indoor spaces, where its blooms will be a focal point.

Care tips
It prefers bright, indirect light; avoid intense direct sun, which can scorch its leaves. Water thoroughly when the substrate is dry to the touch, but ensure excellent drainage to prevent waterlogging, as it is prone to root rot. Use a well-aerated, fast-draining substrate, such as an orchid mix or bark-based medium. A common mistake is overwatering, especially in winter, which can be fatal for this Hoya.
