In the garden

Mentha longifolia is a perennial herb in the genus Mentha, native to parts of Europe, North Africa and south‑west Asia. It grows to roughly 1.0 m and flowers from June to September, making it a mid- to late-summer presence in the border. The foliage is notably fragrant and lends the plant its primary appeal in the garden. Give it full sun and soils that hold moisture without waterlogging; the species tolerates sandy, loamy or clay textures so long as drainage is reasonable. In UK terms H7 denotes fully hardy, so plants can remain in the ground through typical winters. The USDA zones 5–9 indicate a similar broad tolerance for climates beyond the UK. Use Horse Mint in herb or cottage-style borders, alongside paths or near seating where passing movement releases the scent from the leaves. Keep it where moisture can be maintained; the combination of summer flowering and aromatic foliage makes it particularly effective planted where the scent can be enjoyed up close rather than tucked in the back of a border. Positioning it beside a terrace or pathway ensures the foliage fragrance is noticed whenever leaves are brushed.
