Hummel's sunset golden jade plant, also known as Crassula ovata 'Hummel's Sunset', is a cultivar of the popular houseplant Crassula ovata, which is native to South Africa.

This cultivar is named for the vibrant colors that develop on the leaves in response to bright light. The leaves are typically green in the center and have yellow, orange, and sometimes even red hues around the edges. This creates a striking sunset-like appearance, which is where the plant gets its common name.

Like other varieties of Crassula ovata, Hummel's sunset golden jade plant is a succulent with thick, fleshy leaves that allow it to store water. It is a slow-growing plant that can eventually reach up to 3 feet (90 cm) tall and wide when grown in ideal conditions.
