Although there are many types of mint that can be grown, each having its own particular flavor, peppermint (Mentha x Piperita) and Spearmint (Mentha spicata) are the most common. The mints grow from 1 to 3 feet and spread aggressively through their underground rhizomes. The mints produce purple flowers.
Mints are extremely robust perennial plants. They prefer a spot in the sun but tolerate a light shade. The mint is propagated by cuttings of stems or roots. Because mints have a prolific growth pattern, they will become invasive in a garden, try to check their growing root system. It is strongly suggested that mints be grown in aboveground containers. Other suggestions for containing mints include the planting of mints in large, bottomless containers that are sunk in the garden. This technique is not always successful. For the plants to remain vigorous, it was suggested to divide them every 3-4 years. In order to preserve the flavor of the leaves, the ears of flowers must be removed as soon as they appear.
The leaves can be harvested as needed, but the more frequently the stems are cut, the more new shoots are produced. It is the new growth that has the most tasty leaves. It is better to take the leaves to dry at the same time as the flowers begin to appear. Bouquets of mint in a glass of water will keep fresh for 3 to 7 days or can be stored in the refrigerator, dry and wrapped in plastic for a week.
