Native to Europe, but introduced as an herb for its fragrance and as an additive in recipes. Widespread in the United States.
A perennial broadleaf plant, with foliage dying back in the winter, with regrowth from the roots in the spring.
Propagation is from seeds or from the spreading rootstock. Will grow in many soil conditions, but moist soils and marsh-like conditions are ideal.
Mature plants may grow to 4 feet tall, as a weak-stemmed, spreading shrub. Highly aromatic leaves with a distinctive spearmint fragrance.
Leaves are oval to lance-shaped, with strongly serrated edges. Leaves are dark green and may be 2.5 inches long.
Flowers are arranged as a series of dense, round clusters along the ends of the stems, and these clusters may be over 3 inches in length. The flowers are typical of mints, being tubular and thin, pale lavender to white, and with extremely long stamens visibly protruding from the flower.
Characteristicts Important to Control:
A perennial that regrows from the roots, and may spread by the roots. Very moist soils are preferred.
