Since these plants grow both in and on top of tree canopies, they adapt well to different light levels—part of what makes them great houseplants. Hoya's thick, waxy leaves store water, so no worries if you forget to water it from time to time—another helpful houseplant trait. When conditions are right, long, leafless tendrils give rise to clusters of fragrant star-shape waxy flowers that bloom for weeks. Genus Name Hoya Common Name Hoya Plant Type Houseplant Height 6 to 12 inches Width 6 to 48 inches Flower Color Pink, Red, White, Yellow Season Features Fall Bloom, Spring Bloom, Summer Bloom Special Features Fragrance Propagation Stem Cuttings Problem Solvers Drought Tolerant Hoya Care Must-Knows Hoya does best planted in moist well-drained light soil and sitting in front of a north window where it gets all but the hottest sun. Especially sensitive to soggy soil, hoya is a houseplant that likes life on the dry side. Wait until the soil surface is dry to the touch before watering. Keep the room temperature at least 50 degrees Fahrenheit and warmer during spring and summer. This plant goes semi-dormant in winter. Fertilize hoya once in spring and again in summer using a general houseplant fertilizer. Follow package directions carefully for application rates. Don't fertilize in winter.

As the stems grow they send out long, leafless tendrils that eventually develop flowers and foliage. Do not cut them off. A mature hoya blooms under bright light in spring and summer when plant growth is most active. (Plants growing in low and medium light produce beautiful foliage and lanky stems but rarely flower.) The waxy porcelain-look flowers appear on knobby spurs that should be left in place for the next round of blossoms. Some gardeners recommend keeping hoya pot-bound to encourage more prolific blooming. Hoya can generally grow in the same pot for years. Here's how to repot a root-bound plant. Was this page helpful?
