Read about Hoya in the Standard Cyclopedia of Horticulture

Hoya (Thomas Hoy was once gardener to the Duke of Northumberland). Asclepiadaceae. Tropical climbing or trailing evergreen shrubs, bearing thick, opposite leaves and odd, often showy flowers in umbel-like clusters, grown under glass and one of them sometimes in window-gardens. Corolla rotate, 5-lobed, thick and more or less waxy in appearance: crown rotate, of 5 thick and compressed fleshy appendages: pollen-masses short, fixed by their base in pairs to the 5 glands of the stigma: follicles acuminate, smooth: sts. twining, or climbing by means of roots. — Species perhaps 100, E. Asia to Austral.; difficult to determine in herbarium specimens. Hoyas are summer-blooming plants, of comparatively easy culture. They need an intermediate or warm temperature. Let them rest or remain very slow in winter (50° in a dryish place), but start them into growth toward spring. In the summer they are sometimes plunged in the border, but better results are to be expected, as a rule, by keeping them in pots in the conservatory. In their growing and blooming season, give plenty of sun and air. They propagate by cuttings of the top-growth in spring, and also by layering. The latter method is particularly adaptable to H. carnosa and other species that climb by means of roots. The only species commonly known is H. carnosa.
