Hoya Gracilis, also known as the Hoya Memoria, is a unique trailing houseplant known for its narrow and flat deep green foliage speckled with white variegation. On occasion, this houseplant will produce pinkish red, scented flowers. The best way to care for your Hoya Gracilis is to keep it in bright, indirect light and allow it to dry out in between watering. These wax plants go beautifully in hanging baskets or on the edge of a shelf, so they have plenty of space to trail as they grow.
