Wax Plant
Hoya carnosa
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.

Fun Facts
Hoya carnosa flowers are nocturnal perfumers -- the sweet scent intensifies dramatically at night, an adaptation to attract nighttime pollinators. The flowers also physically drip nectar, which is quite a surprise the first time you notice a puddle under your plant.
Pet safe
Non-toxic to dogs, cats, and humans according to ASPCA and NCSU Extension. The milky sap may cause mild skin irritation in sensitive people when the plant is cut.
