Description

 

Stachys tenuifolia, or Smooth Hedge-nettle, is an herbaceous perennial flowering herb in the mint family. The root system consists of a taproot and rhizomes. This plant often forms vegetative colonies, like many other members of the Mint family.

The plant prefers partial sun and moist conditions, but also tolerates light shade and full sun. The soil should contain sufficient organic material to retain moisture. If this plant dries out, the leaves have a tendency to turn yellow or brown, and the entire plant may die. It is typically found in low woods, and shores.

The plant produces seeds, but often reproduces by means of rhizomes and tubers. Small segments of rhizome can sprout into new plants or the tuber may be transported to a new area.

    Flower Description:
    The central stem terminates in a inflorescence that has whorls of flowers at intervals along its length. This inflorescence can vary from 2 to 8 inches in length. The tubular corolla of each flower is about 1/3 inch long and divided into 2 lips. The hairy upper lip functions as a protective hood, while the lower lip is divided into 3 lobes (a central lobe and two smaller side lobes), which functions as a landing pad for visiting insects. The flowers are light pink or white, often with rosy pink splotches within the throat. The green calyx is hairless and at least half as long as the tube of the corolla (not including the lips). It is divided into 5 triangular segments that curl outward as the ovaries mature. The blooming period occurs during the summer and lasts about 1-2 months.
