Description
Oxyria is a genus of flowering plants that belongs to the family Polygonaceae. This genus consists of only two species, Oxyria digyna and Oxyria sinensis. These plants are also known as mountain sorrels, as they are commonly found in high-altitude regions of the Northern Hemisphere. The name “Oxyria” is derived from the Greek words “oxys” and “orea”, which mean “sour” and “mountain” respectively. This name refers to the sour taste of the leaves and its habitat in the mountains.

Appearance
Oxyria plants are small, herbaceous perennials that typically grow up to 10-25 cm in height. The stems of these plants are slender and red or green in color. The leaves are basal, meaning they grow from the base of the plant, and are generally heart-shaped or kidney-shaped. The leaves are typically green in color, but may turn red in fall.

Care Guide
Oxyria plants are relatively easy to care for. Here are some tips for caring for these plants:
Water: Oxyria plants prefer moist soil, so be sure to water them regularly. However, be careful not to overwater them, as this can lead to root rot.
Fertilization: Oxyria plants do not require fertilizer, but you can use a slow-release fertilizer in early spring if you wish.
Soil: Oxyria plants prefer well-draining soil that is rich in organic matter. They can tolerate a wide range of soil types, but do best in slightly acidic soil.
Sunlight: Oxyria plants prefer partial shade to full sun. In hotter climates, they may do better in partial shade.
Hardiness Zones: Oxyria plants are hardy in USDA zones 3-7.
Common Pests & Diseases
