Grow Mentha × 'Citrata' (Eau de Cologne Mint 'Citrata') for its fresh, citrusy fragrance and versatile garden use. You can enjoy the leafy stems for teas, cold drinks, desserts, and garnishes, and you can also let it flower for a soft, airy look in summer.
Give it consistent moisture and rich, well-drained soil, though it will tolerate a wide range of garden soils if it is not allowed to dry out for long periods. Plant it where it can get full sun to part shade; in hotter areas, afternoon shade can help keep leaves tender and aromatic.
This mint typically reaches about 12-36 inches tall and can spread quickly. For easier control, you can grow it in a pot or sink a container into the ground. If you plant in open soil, consider using edging or a dedicated bed so it does not wander into nearby plantings.
To keep growth lush, pinch or harvest regularly and cut stems back as needed through the season. You can divide established clumps to refresh plants and to share starts. Expect lavender-toned flowers in summer that can draw pollinators when you let a portion of the planting bloom.
