Hoya kerrii is in the milkweed family Apocynaceae. Commonly known as Sweetheart Hoya, it is native to southeast Asia. This species, like many other Hoyas, is a vining plant that can grow to over 2 meters tall. Sweetheart Hoya produces thick heart-shaped leaves, which make it popular as a gift for Valentine’s day in some parts of the world. Arguably more attractive are the terminal clusters of star shaped flowers. The flowers give off a sweet fragrance, and produce copious amounts of sweet, amber colored nectar that collects at the tips of the petals.
