Hoyas, or Wax Plants, have been one of my favorite vining house plants ever since I inherited one with the instructions: “just barely water it, and keep it in a bright place. You won’t believe the flowers!” That is the type of plant I like: easy care with a surprise in store--fragrant flowers. This Hoya carnosa is one of the most common varieties available, and has my house smelling like sweet chocolate nectar through the evening as it twines along my window!
Hoyas are a genus in Asclepiadaceae (Milkweed), a subgenus of Apocinaceae (Dogbane).
Native throughout Asia, India, Southeast Asia, and Australia, the succulent forms of Hoyas are often epiphytic (live up in trees), or scramble through rocky areas of their tropical and subtropical habitats. The structure of their individual fragrant, plump star-shaped flowers is worth close examination and admiration. They exhibit a variety of textures from waxy to furry, and a range of colors and combinations from creams to pink blush and burgundy-red.
We have some fun varieties in at the nursery right now, and we have been enjoying combining them with other succulents that can tolerate growing indoors or outdoors in bright shade conditions. I use hoyas to spill over the side of a pot. (Put the container garden up on a stand so the plant has room to vine around!) You can also train hoyas to grow along a window or around a wreath frame.
