Sweetheart hoya plant, also known as Valentine or sweetheart wax plant, is a type of Hoya appropriately named for its thick, succulent, heart-shaped leaves. Like other varieties, sweetheart hoya plant is a stunning, low-maintenance indoor plant.
Native to Southeast Asia, sweetheart hoya is often a quirky Valentine’s Day gift with a single 5-inch leaf planted upright in a small pot. Although the plant is relatively slow-growing, it appreciates a hanging basket, where it eventually becomes a bushy mass of green hearts. Mature plants can reach lengths of up to 13 feet. During the summer, clusters of white, burgundy-centered blooms provide bold contrast to the deep green or variegated leaves. One mature plant can display up to 25 blooms.
