Hoya (Wax Plant)
Hoya carnosa
Family Apocynaceae
Hoya flowers look manufactured — geometric clusters of porcelain stars, faintly perfumed and dripping actual nectar — carried on trailing vines of thick, waxy leaves. When a wax plant finally blooms, people photograph it. Until then it's simply a handsome, patient hanging plant.
Pet-safe and semi-succulent, it prospers on bright light and benign neglect, blooming best when comfortably rootbound — laziness is genuinely part of the recipe. Vines run to ten feet over the years. Hang one in a bright window and let it take its time.
