Hoya kerrii, also called Hoya hearts or Sweetheart plant is a species of Hoya native to the south-east of Asia. As the thick leaves are heart-shaped, the plant is sometimes named "lucky-heart".

Hoya kerrii is a climbing plant that can grow up to 4 meters high (around 13 feet). Stems have a diameter of 7 mm. The leaves are 6 cm wide, 5 mm thick. The leaves are often sold individually in pots and can last years. It is important to note that the leaves will only rarely develop into a full vining plant as they do not have rooting nodes.
