Catmint Seeds 6400.
Low-Growing Aromatic Mounds with Soft Violet Flower Spikes for Sun-Drenched Borders.
Catmint (Nepeta mussinii) is a beloved open-pollinated perennial favoured for its low-growing, mounded habit and soft, violet-blue flower spikes rising 30 cm in height. Spreading up to 40 cm across, its aromatic, grey-green foliage produces a long-lasting summer display that naturally draws pollinators, butterflies, and feline visitors alike. Exceptionally easy to establish, Catmint will flower in its very first season when started early indoors. Hardy down to Zone 4, this drought-tolerant performer thrives in full sun, making it ideal for rock gardens, edging pathways, or filling sunny perennial borders.

What you need to know to Plant & Grow
Catmint is simple to start indoors or direct-sow into garden beds.
-
Indoor Sowing: For first-year blooms, start seeds indoors in a quality soilless starter mix during February. Barely cover the seeds and maintain a temperature of 20°C for the 10 day germination period. Move sprouted seedlings under grow lights at slightly cooler temperatures before hardening off and transplanting outdoors after spring frost danger passes.
