Wax plants, or hoyas, are twining vines known for their waxy flowers and foliage. Their sweetly scented flowers are produced on mature plants.
Wax plant vines need high light and evenly moist potting soil that drains well. A trellis should be provided to support their growth. They are best used as potted or hanging basket plants.
They like room temperatures at 70 to 75 degrees Fahrenheit during the day and 60 to 65 degrees at night. Unlike other houseplants, wax plants can tolerate temperatures as low as 40 degrees when not in active growth. They will thrive in 30 to 40 percent relative humidity and should be fertilized every month with a half-strength solution of an all-purpose soluble fertilizer.
Wax plants may be propagated by stem cuttings. They occasionally attract pests including mealybug and spider mites.
