About Hoya crassicaulis
Hoya crassicaulis, commonly known as wax flower, is a climbing or trailing plant from the Apocynaceae family, prized for its large, glossy green succulent leaves and spectacular umbel-shaped inflorescences with waxy, yellow or greenish flowers that exude nectar. It is ideal for hanging baskets or for climbing a trellis in bright indoor spaces, adding an exotic and tropical touch. Its flowers, which can reach 5 cm in diameter, are a true visual and olfactory spectacle, especially at dusk.

Care tips
It requires bright, indirect light to bloom profusely; avoid intense direct sun, which can scorch its leaves. Water moderately, allowing the top few inches of the substrate to dry out completely between waterings, as it is susceptible to root rot. Use a well-draining and airy substrate, preferably an orchid or succulent mix with bark and perlite. A common mistake is to move it when it is forming buds, which can cause the flowers to drop.
