Plant of the Day: Mentha

DESCRIPTION: This is a large group of well-known perennial herbs, which are widely spread over the temperate parts of the world. Mentha includes the Apple Mint, Curly Mint, Pennyroyal, Peppermint, Pineapple Mint, Spearmint and Water or Bog Mint. Following are descriptions of each variety.
Apple Mint (M. suaveolens) - This hardy perennial is a very robust grower. Apple Mint has interesting light green leaves. They are somewhat hairy on the upper surface and downy underneath, with serrated edges. They can grow up to 3 feet high, but should be kept lower.
Curly Mint (M. spicata variety crispii) - This plant is valued more for its intricately curled, fringed leaves than for its fragrance. The foliage is dark green and lightly splotched with a contrasting lighter green. They can grow up to 2 feet high and are invasive. Chefs like Curly Mint for garnishes, but prefer the pleasant flavor of Spearmint and Peppermint.
Pennyroyal (M. pulegium) - This creeping Mint is used once in a while as a ground cover in cool climates. It has many stems, which grow up to 12 inches high and are covered with small, round to oval, dark green leaves. In the summer it produces bluish-lilac blossoms. Pennyroyal has an enjoyable lemony aroma and is used to flavor meat puddings and fish entrees.
Peppermint (M. piperita) - This spreading plant has a sharp, penetrating yet pleasant, mint aroma. It grows 1 to 2 feet high, but can reach 3 feet when in bloom. The lance-shaped leaves are deeply notched when mature and the flowers are usually purple.
Pineapple Mint (M. suaveolens 'Variegata') - Pineapple Mint is a variegated hybrid of Apple Mint with white or cream blotches on its leaves. It does have a slight Pineapple scent, but the aroma isn't always detectable. This Mint is good for garnishes because the thick leaves are slow to wilt.
Spearmint (M. spicata) - This is considered one of the most popular and versatile garden Mint. Spearmint has a fruity aroma and flavor and blends well in many foods, including salads, sauces, teas and dips. This plant can reach 2 to 3 feet in height when in bloom. It has bright green leaves and purple flowers. Its toothed leaves lack stems, distinguishing this plant from Peppermint.
Water or Bog Mint (M. aquatica) - This aggressive Mint is great for growing along the margins of water gardens, though care must be taken that it doesn’t become troublesome. The Bog Mint grows to a height of 2 or 3 feet. It produces pairs of very fragrant, elliptic-shaped, serrated leaves that are usually tinted with purple and shaded with even more purple on their undersides. The leaves grow from reddish colored stems. In the summer, whorls of lilac colored flowers grow at the stem tips. The leaves may be used to flavor salads and teas.

VARIETIES:
Apple Mint - M. suaveolens.
Curly Mint - M. spicata variety crispii.
Pennyroyal - M. pulegium.
Peppermint - M. piperita.
Pineapple Mint - M. suaveolens 'Variegata'.
Spearmint - M. spicata. The large-leaved cultivar Scotch and the small-leaved Native contain the most mint oil. Kentucky Colonel is a strongly scented hybrid favored for juleps. Curly and variegated cultivars also exist.
Water or Bog Mint - M. aquatica.

Mentha (also known as Mint, from Greek míntha, Linear B mi-ta) is a genus of flowering plants in the family Lamiaceae (mint family).  The species are not clearly distinct and estimates of the number of species varies from 13 to 18. Hybridization between some of the species occurs naturally. Many other hybrids as well as numerous cultivars are known in cultivation. The genus has a subcosmopolitan distribution across Europe, Africa, Asia, Australia, and North America.
Mints are aromatic, almost exclusively perennial, rarely annual, herbs. They have wide-spreading underground and overground stolons and erect, square, branched stems. The leaves are arranged in opposite pairs, from oblong to lanceolate, often downy, and with a serrate margin. Leaf colors range from dark green and gray-green to purple, blue, and sometimes pale yellow. The flowers are white to purple and produced in false whorls called verticillasters. The corolla is two-lipped with four subequal lobes, the upper lobe usually the largest. The fruit is a small, dry capsule containing one to four seeds.
While the species that make up the Mentha genus are widely distributed and can be found in many environments, most Mentha grow best in wet environments and moist soils. Mints will grow 10–120 cm tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, mints are considered invasive.
