Viola palmata
Wood violet
 
Viola palmata, the wood violet, is a low-growing perennial that typically reaches 6–10 inches in height. It is easily recognized by its deeply lobed, palm-shaped leaves and its violet to purple flowers that bloom in spring. This species grows best in part shade with average, well-drained soils and often forms small colonies that serve as an attractive groundcover. As an early bloomer, it provides an important nectar source for pollinators emerging in spring.
