Sweetheart Plant (Hoya kerrii)

Native to Southeast Asia, Hoya kerrii is a climbing, semi-succulent epiphyte instantly recognized by its obcordate, thick, and heart-shaped foliage. Frequently marketed as a single rooted heart-shaped leaf, it requires a stem node to establish vigorous vine-like vegetative growth. In mature specimens, it produces hemispherical umbels of velvety, star-shaped cream flowers that exude distinctive rust-red nectar droplets.
