Its aromatic foliage, when crushed or brushed against, releases a pleasant, minty fragrance, adding a sensory experience to the garden.

Companion Plants: To create a diverse and attractive garden display, pair Silver-Leaf Mountain Mint with other native perennials that share its love for sun and pollinators.

Once established, it is quite drought-tolerant. Cutting back the plant in early spring encourages fresh, vigorous growth and can help maintain a more compact form. No special fertilization is necessary, as the plant is adapted to thrive in natural soil conditions.
