Cissus trifoliata aka Vine Sorrel

Cissus trifoliata, commonly known as possum-grape, sorrelvine, vine-sorrel, or hierba del buey, is a New World plant species in the grape family. It is a woody perennial vine that can trail or climb, native to the southern United States, Mexico, Venezuela, Colombia, and possibly Ecuador. It can also be found on various Caribbean islands. The plant has palmately tri-lobed leaves that are fleshy or semi-succulent, and they tend to persist but are cold-deciduous at around 26F. The flowers are creamy yellow with spreading petals, and the fruits are black or deep purple juicy berries with 1-4 seeds. However, it is important to note that the tubers of this plant are considered poisonous, and contact with the plant can cause dermatitis in individuals with sensitive skin. Possum-Grape, a rare houseplant, is easy to grow and requires regular watering. It thrives in abundant sunlight and should be placed within 3 feet of a window. Well-draining soil is preferred, and the plant does not usually require additional fertilizers if repotted when it doubles in size. Possum-Grape belongs to the Cissus genus and is native to the Southern United States.
