Like a cloud of confetti, tiny white flowers (sometimes touched with pale blue) appear from early summer to fall. Undemanding and dependable, calamint provides the perfect foil for other summer bloomers and foliage. This full-sun perennial has a low mounding or bushy habit, ideal for the front of the border, rock gardens, and more.

While durable and pest-free, calamint also checks two important boxes for gardeners: bees and other pollinators work the flowers throughout the summer and the aromatic foliage is deer-resistant.

Calamintha nepeta subsp. nepeta is a favorite low-growing component in stylized meadows, matrix plantings, and other modern perennial designs. Gardeners can also create a lovely monochromatic garden with more sure-thing perennials including past PPOYs such as Anemone xhybrida ‘Honorine Jobert’ and Phlox paniculata ‘David’, or complemented with ornamental grasses such as Panicum virgatum ‘Northwind’ (switchgrass) or Schyzacharium scoparium (little bluestem).
