I got two leafs as a start from a friend's Mother and within six months, with full sun, it has grown from two leafs to over a foot long. I can't wait for it to bloom, but hear it can take years before that will happen.

Hoya's are easy to take care of, we also put ours outdoors in the shade. They are easy to propagate by cuttings. They have strong fragrance specially at night. It smells delicious :)

All of my Hoyas are in shade outdoors, and this is the one that does best for me. It is the greenest, bushiest, and by far the fastest growing. Its new leaves are a dark maroon color, with the variegation showing up later. The beautiful pink-purple flowers are wonderfully fragrant. It has become a clear favorite, with only one problem--its the only one of my Hoyas that has stuck onto and grown up my wall.

Inherited one of these plants about twenty years ago. Does not require much of anything except a little water once a week. My main plant blooms, but my cuttings have never bloomed. My Grandmother gave it to me. It never bloomed for her but she had the opposite problem - all the cuttings she gave away bloomed! Be patient and enjoy the exotic vines and ease of care.

I have enjoyed 2 well-established wax plants for 25 years. In northern NJ Zone 6, they are obviously houseplants.
Both hang in east-facing windows, at opposite ends of the house. Yet their bloom seasons are not always the same. Both tend to bloom sometime between early July & mid-August, but they are rarely "in step". Occasionally, one will also bloom in late February or early March.
Wax plants become agressively "up-your-nose" odiferous, at night, when blooming. Their overpowering scent can knock you over like a brick upside the head! Thus, never, ever place them in a bedroom, or a primary room such as a living room. They are best located in den's, bathrooms, & kitchens, where their scent can waft, somewhat diluted, into the rest of the house. Though closely related to milkw... read more

b>H. pubicalyx cv. Pink Silver, created by Mr. Hummel, a hybridizer from California.
One of the more cold tolerant Hoyas (>4°C[39°F]) but will not tolerate frost.
Exudes translucent sap when cut or broken.
Can be grown in hanging baskets or trained to trellis.
Easy and fast growing plant which, once established, flowers profusely.
Plant will send out long, bare twining shoots that will grow leaves later on and may bear flowers.
Flowers are very fragrant especially during evening hours. Smell of flowers can become overpowering indoors.
I recommend use of a well draining soil, water well and do not let the soil dry out completely inbetween watering.
This commonly available cultivar is sold under many other names. This is most likel... read more
