Cinnamon Hoya
Hoya lacunosa (HOY-ah lak-uh-NO-suh)
Cinnamon hoya is a delicate, compact, creeping, climbing epiphyte and lithophyte vine native to the tropical forests of Southern Myanmar and West and Central Malaysia. Typically, it is found along forest edges in its native habitat, climbing on tree trunks and limbs. The plant has slender, smooth stems and dense, deep green, waxy leaves. Its flowers are arranged in hanging umbels on a sturdy stalk. There are up to 30 flowers per umbel, and each bloom is white, star-shaped, fuzzy, and tightly curled with a yellow corona in the center. The blooms have a cinnamon fragrance, especially at night. This plant has a similar habit and growth pattern to Hoya bella. Cinnamon hoya is a member of the dogbane family (Apocynaceae). The specific epithet, lacunosa , means "full of little cavities' and describes the pitted texture or the depressed areas between the veins on the outer surface of the plant's leaves. Prefers bright, indirect light or partial shade and grows well in a moist, well-drained orchid potting medium. A mixture of perlite, pine bark, sand, and peat moss may also be used. Hanging baskets made with coconut fibers provide good airflow to the plants' roots. The plant should be kept moist, but allow it to dry out somewhat between each watering. This plant also prefers warm temperatures between 68 and 77 degrees Fahrenheit and humidity levels between 50 and 70%. It is winter hardy in zones 10b to 12b. Propagated by stem cuttings. Avoid removing spent flower stalks or peduncles. The new flowers will form on the old spurs. If needed, prune only to maintain the plant's shape or to remove dead leaves or stems. Cinnamon hoya is a highly prized ornamental houseplant with its cinnamon fragrance, white fuzzy flowers, pitted foliage, and compact habit. Insects, Diseases, and Other Plant Problems: No significant insect pests or diseases. Monitor for mealybugs and spider mites. Overwatering can cause root rot, and fungal diseases such as powdery mildew and leaf spot can occur. Direct sun can cause leaf scorch, while inadequate sunlight will make the plant weak and leggy. The sap of the plant is white and milky, and may cause skin irritation. Wear protective gloves when handling the plant. More information on Hoya .
