Spearmint Oil Guide

Mentha spicata (Spear Mint or Spearmint) is a species of mint native to much of Europe and southwest Asia, though its exact natural range is uncertain due to extensive early cultivation.[citation needed] It grows in wet soils[2][3]. It is an invasive species in the Great Lakes region where it was first sighted in 1843[4].

It is a herbaceous rhizomatous perennial plant growing 30–100 cm tall, with variably hairless to hairy stems and foliage, and a wide-spreading fleshy underground rhizome. The leaves are 5–9 cm long and 1.5–3 cm broad, with a serrated margin. Spearmint produces flowers in slender spikes, each flower pink or white, 2.5–3 mm long and broad.[3][5]

Hybrids involving spearmint include Mentha × piperita (Peppermint; hybrid with Mentha aquatica), Mentha × gracilis (Ginger Mint, syn. M. cardiaca; hybrid with Mentha arvensis), and Mentha × villosa (Large Apple Mint, hybrid with Mentha suaveolens).[3]

The name 'spear' mint derives from the pointed leaf tips.[6]...
