bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) year-round. Good light encourages blooming; low light (more than 8 feet from a window, or a north-facing room. A grow light 10-12 inches away works great if your windows are not cutting it) means fewer or no flowers. Avoid moving the plant once buds have formed, as even a small location change can cause bud drop.Light

Wax Plant

Hoya carnosa

Moderate

The Wax Plant earns its name from the thick, waxy leaves and the utterly alien-looking star-shaped flowers that cluster into perfect little globes and drip nectar -- yes, they actually drip. You can grow it in a hanging basket or train it up a trellis, and if you leave the spent flower spurs alone, those same spurs will keep producing blooms year after year for as long as you own the plant.
