There are herbaceous plants everywhere in the countryside, some of which are widely distributed and have a particularly tenacious vitality, and many of them are treated as weeds by farmers. People who understand the function of plants will naturally regard it as a treasure, and maybe even plant it specially. The herbs we share today are common plowshares in rural areas. The plants are short and special in shape, especially the leaves like plowshares, which have purple flowers and good ornamental value.

Plough grass, also called viola yedoensis or arrowhead grass, is mostly distributed in southern areas, such as Hunan, Zhejiang, Guangdong, Guangxi and Fujian. It likes to grow in a humid environment, and its plants have certain shade tolerance and cold tolerance, and it grows vigorously all year round, as long as the soil is fertile, it can grow well. It's good to be a small potted plant, and the piece planting is more ornamental.

The perennial herb of Violaceae is 4~ 14 cm high. When it doesn't bloom, such a small plant is really hard to find. Although the plant is small, it grows very steadily, and the main root is thick and vertical and deeply rooted in the soil. It takes some effort to pull it out.

Plough grass has no stems on the ground, only clustered leaves, with blunt serrations on the edges and slightly purple below. Pedicels are slender and longer than foliage, and lilac flowers are bisexual.
