Hoya — 197 species

Part of the Hoyas & relatives family (Apocynaceae)

Hoyas are a genus of tropical climbers and trailers celebrated for their waxy, often fragrant flower clusters and thick, succulent-like leaves — from the heart-shaped Sweetheart plant to the vigorous Hoya pubicalyx and classic Wax plant. They prefer bright indirect light and are famously drought-tolerant; allow the potting mix to dry out almost completely between waterings. Overwatering is the primary cause of decline. According to the ASPCA, all Hoya species are non-toxic to cats and dogs, making them an excellent choice for pet-friendly homes.
