Hoya kerrii, the Sweetheart Hoya, is a slow-growing semi-succulent vine famous for its thick, glossy, heart-shaped leaves. Often sold as a single rooted leaf in a small pot, it is a beloved gift plant, though a full vining plant develops trailing stems and can eventually bloom with clusters of star-shaped flowers. The fleshy leaves store water, making it forgiving of occasional neglect and well suited to busy plant lovers. It thrives in bright indirect light and a chunky, fast-draining mix. In India it adapts well indoors near bright windows, rewarding patience with steady, long-lived growth.
