The Hoya Sweetheart Variegated commonly called the wax plant is a non-blooming houseplant with heart-shaped leaves. This Variegated version has a splash of yellow on the leaf. The vines are wood-like and the leaves are waxy. Native to tropical Asia, these plants do well in warm weather. This single-leaf offering is a very slow grower, but is also extremely hardy. Ideal as a novelty gift, it is more of an ornament than a needy houseplant. For the houseplant enthusiast, proper care and patience can be rewarded with a striking growth of multiple heart-shaped leaves on vines.
