Lespedeza bicolor aka Shrubby Bushclover

Lespedeza bicolor, also known as shrubby bushclover, shrub lespedeza, and bicolor lespedeza, is a deciduous medium-sized shrub native to Asia. It was introduced to the United States in the mid-1800s as an ornamental plant and has since been used for erosion control, revegetation of strip mined lands, and improving wildlife habitats. While it is widely grown as an ornamental plant, it has also become an invasive species in some regions, such as the southeastern United States. The plant offers dark green trifoliate leaves on gray to green stems and long arching sprays of five to fifteen small magenta-purple pea flowers. It is drought-tolerant and grows well in infertile, medium-dry, well-drained soil in full sun to part shade, making it a good choice for difficult sites. Its roots fix nitrogen, and in harsh climates, it can be cut to the ground in late winter or early spring and will regrow to five feet tall in a single season. As a houseplant, Shrubby Bushclover is super rare and easy to grow, but it needs regular watering to thrive. It prefers long-lasting, direct light and should be less than one foot from a window. The plant likes soil that is well-draining, and it shouldn't need added fertilizers if you repot each time it doubles in size. Belonging to the Lespedeza genus, this plant is native to Southeastern Siberia to Japan.
