Care essentials
White mountain mint grows best in full sun in NE Florida; it tolerates part shade but becomes leggy and blooms less freely. Afternoon shade can help in zone 9b's hottest months.
Drought-tolerant once established in well-drained, sandy NE Florida soil. Water weekly during the first growing season; thereafter rely on rainfall except in extended dry spells. Good drainage is essential — avoid wet feet.
Thrives in lean, sandy to loamy, well-drained acidic soils — no rich amendments needed. Avoid high-nitrogen fertilizers, which reduce flowering. Divide clumps every 3–4 years to control spread; cut back to ground in late fall after dormancy.
