Berberis thunbergii aka Japanese Barberry

Berberis thunbergii, also known as the Japanese barberry, Thunberg's barberry, or red barberry, is a species of flowering plant in the barberry family Berberidaceae. It is native to Japan and eastern Asia, but has become widely naturalized in China and North America, where it is often grown as an ornamental plant. This deciduous shrub can grow up to 1 meter tall and 2.5 meters wide, with green leaves that turn red in the autumn, pale yellow flowers in spring, and brilliant red fruits in autumn. However, it has also become a problematic invasive species in many places, leading to declines in species diversity, increased tick habitat, and soil changes. The genus name comes from the Latinized form of the Arabian name for the fruit, while the specific epithet honors Swedish botanist Carl Peter Thunberg, who reportedly identified this species in Japan in 1784. Japanese Barberry is a relatively rare houseplant that is easy to grow and needs regular watering to thrive. It does best in long-lasting, direct light and likes soil that is well-draining. If you repot it each time it doubles in size, it shouldn't need added fertilizers. As a member of the Berberis genus, it is native to Asia.
