The mentha plant genus is more commonly called what?
Mentha in the ground, or planted above ground in tubs and barrels. Some mints can be propagated by seed, but growth from seed can be an unreliable method for raising mint for two reasons: mint seeds are highly variable — one might not end up with what one supposed was planted — and some mint varieties are sterile. It is more effective to take and plant cuttings from the runners of healthy mints. The most common and popular mints for commercial cultivation are peppermint ("Mentha × piperita"), native spearmint ("Mentha spicata"), Scotch spearmint ("Mentha x gracilis"), and cornmint ("Mentha arvensis"); also
Mentha oblong to lanceolate, often downy, and with a serrated 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 nutlet, containing one to four seeds. While the species that make up the genus "Mentha" are widely distributed and can be found in many environments, most grow best in wet environments and moist soils. Mints will grow 10–120 cm tall and can spread over
