Sweetheart Plant, Sweetheart Hoya, Valentine Hoya, Heart Leaf Hoya, Wax Hearts, Hoya Hearts, Lucky Hearts Plant
Summary
Sweetheart plant is a heart-shaped leaf evergreen vine native to Southeast Asia, growing slowly as an epiphytic/lithophytic climber with thick waxy leaves. It trails or climbs and can bear clusters of small waxy star-shaped flowers; commonly sold as a single heart-shaped leaf cutting, with variegated forms available.
Cultivation focuses on bright indirect light with some direct sun tolerated after acclimation, well-draining airy soil, and waterings that occur only after the soil dries to avoid soggy roots; typical temperature 60–80°F and humidity 40–60%; use containers with drainage and repot every 2–3 years; propagation mainly via stem cuttings with nodes (leaf cuttings require a node), and pruning is minimal; suitable for hanging baskets or trailing displays indoors.
