Perennial Calamint - 2021 Perennial Plant of the Year will be CALAMINTHA nepeta ssp. nepeta This sun-loving perennial is the perfect choice for attracting butterflies, hummingbirds and is bee friendly. Tiny, white flowers cover the bushy habit. Since this is in the mint family, the leaves carry a mint scent. Perfect for rock garden enthusiasts and herb gardens. Use in the landscape as you would Nepeta (Catmint). Most any sun loving perennial would make a great companion plant, but the Grand Cascade Butterfly Bush, Blue Oat Grass, Purple Dome Aster and Firecracker Sedum would really highlight the beauty of the Calamint.

This will stimulate the growth of fresh new leaves. 12-16" tall, 12-16" wide, full sun, early summer to early fall bloom. Zones 5-9. Potted in 3" pot.
