Blue Catmint Seeds (
Nepeta
)
Soft Lavender-Blue Blooms with a Relaxed Cottage Garden Feel
Blue catmint is a beloved perennial known for its billowy mounds of lavender-blue flowers and softly aromatic gray-green foliage. Blooming generously from late spring into summer, and often reblooming with a light trim, catmint brings a calm, dreamy quality to garden borders, pathways, and cottage-style plantings.
Highly attractive to bees, butterflies, and other pollinators, blue catmint is also famously tough. It thrives in heat, tolerates drought once established, and resists deer and rabbits. With its tidy, mounded habit and long bloom season, catmint is a reliable workhorse that looks effortlessly beautiful all season long.
Perfect for edging beds, softening hardscapes, or pairing with roses, salvias, and grasses.
