Corsican mint (Mentha requienii).
Of the myriad mints available to fragrance gardeners, the lesser-known Corsican mint is my favorite.
The aroma and flavor are similar to peppermint (M. xpiperita), but to my senses brighter and perkier.
A true native of Corsica, as well as Sardinia and mainland Italy, this perennial mint forms a half-inch-high slender-stemmed mat of miniscule rounded leaves.
Whorls of tiny, tubular, lilac-colored blossoms appear in summer. The leaves can be used to flavor salads and drinks and to make a refreshing herbal tea.
Hardy from Zones 6 to 9, Corsican mint prefers a moisture-retentive rich soil and a shaded site away from the hot sun.
It is a perfect herb to plant between flagstones of a woodland garden path, where each footfall releases a whiff of fragrance.
