Coastal buckwheat is a flowering plant native to coastal regions of North America, particularly found in sandy or rocky habitats. It belongs to the Polygonaceae family and is known for its small, white to pink flowers that bloom in clusters. This plant typically grows low to the ground, forming dense mats that help stabilize the soil and prevent erosion. The leaves of coastal buckwheat are often narrow and linear, adapting well to its harsh coastal environment. It plays a crucial role in supporting local ecosystems by providing habitat and food for various insects, including pollinators like bees and butterflies.
