What Exactly is Ribseed Sandmat?

This native North American plant is what botanists call a forb – essentially a non-woody plant that completes its entire life cycle in a single growing season.
The plant gets its common name from the distinctive ribbed seeds it produces, and sandmat refers to its tendency to form low, spreading mats close to the ground. It’s not the showiest plant in your garden toolkit, but it has its place in the native plant world.
