Hoya is a genus of succulent vines. One of the most common are Hoya carnosa or Wax plant. The leaves have a very thick wax coating to slow water loss. They really look like a fake plant. The flower habit is a cluster of small pink star-shaped flowers located on a little spur. Hoyas are native to Asia and Australia.

Varieties: 'Krinkle Kurl' or Hindu rope. The leaves are very contorted making a rope-like appearance. This is a very slow growing plant.
'Tricolor' has a white edge which make the plant attractive. The white area lack chlorophyll which reduces the speed the plants grows. If a stem goes all white it will not be able to grow on its own. Stem that go all green will not revert back. If you are trying to propagation it use only stems in the correct coloration.

Fertilizer: When this plant is growing it needs to feed regularly.

Watering: You do not want the leaves to wilt but the plant needs to be on the dry side between waterings. This is more true in the winter than the summer heat.

Soil: You want a well draining mix. You can use any kind of pot but plastics or glazed ceramics will take longer to dry out. A clay will need to be water more often. This plant likes to be root bound to flower.

Flowering: This plant can bloom at any time but seems to favor blooming in cool weather. The plant flower on little spur do not remove these after flowering. The plant will regrown flowers on this spurs.

Propagation: Cutting can be rooted in soil. You want them shaded from too much sun since they can dry out before rooting. Another method is air layering. You will need some clear plastic and sphagnum moss. You take a thick stem and cut slightly in the side and cover the cut with moist sphagnum wrapped with plastic. The moisture will allow rooting and the partial stem keeps it alive until it roots. This is the same method that they use for rubber trees. When you see roots forming in the plastic you know that you can sever the stem and pot up the cutting.
