Mentha longifolia aka Wild Mint

Taxonomy ID: 4507

Mentha longifolia, also known as horse mint, fillymint, or St. John's horsemint, is a species in the genus Mentha. It is native to Europe (excluding Britain and Ireland), western and central Asia, and parts of northern and southern Africa. This attractive perennial herb has spreading growth and aromatic, silvery-grey green leaves. Although its flavor is not as strong as true culinary mints, it is still a popular choice. In the summer, short, dense spikes of pale pink flowers emerge, making it an excellent choice for attracting butterflies and for flower arranging. This highly variable plant has a peppermint scent and features erect to creeping stems, ranging from 40 to 120 cm tall. The oblong-elliptical to lanceolate leaves are 5-10 cm long and 1.5-3 cm broad, with a green to greyish-green color above and a white underside. The lilac, purplish, or white flowers, measuring 3-5 mm long, grow in dense clusters on tall, branched, tapering spikes. Flowering typically occurs in mid to late summer. Mentha longifolia spreads through rhizomes, forming clonal colonies.

With some care and attention, your Horsemint will be sure to bring you many years of beauty and enjoyment.
