Persicaria

Persicaria is a genus of flowering plants that belongs to the family Polygonaceae. They are commonly known as "smartweeds" and are prized for their attractive foliage and colorful flowers. Persicaria plants are native to Asia, Europe, and North America, and are now grown in many other parts of the world as ornamental plants.

Persicaria plants have upright or trailing stems that can reach up to six feet in height. The flowers are typically pink, red, or white, and have small, bell-shaped petals that are arranged in spikes or clusters. The foliage of Persicaria plants is often green or variegated, and can be quite ornamental, with lance-shaped or heart-shaped leaves.
