Grandview Catmint is a charming heirloom cultivar of Nepeta subsessilis that transforms mid-summer gardens with soft pastel spikes of blue, pink, and white flowers. Hardy from zones 3 to 7, this spreading perennial reaches 12 to 24 inches tall and blooms around 90 days from seed, attracting a parade of pollinators including hummingbirds, butterflies, and bees. It thrives in full sun with moderate water and spreads to about 18 inches wide, creating romantic drifts of color that work equally well in borders, containers, or pollinator gardens.

The flower spikes combine soft pastel blue, pink, and white in a single plant, creating a romantic color effect that appeals to both gardeners and pollinators. Cats love this plant as much as people do, and it also draws songbirds, hummingbirds, butterflies, and bees in abundance. Its spreading, mounding habit reaches just 1 to 2 feet tall and equally wide, making it compact enough for small spaces yet generous enough to fill in garden gaps quickly.
Grandview Catmint thrives as an ornamental herb in perennial borders, pollinator gardens, and cottage-style plantings. Its fragrant foliage and prolific flowering make it an excellent choice for attracting beneficial insects and hummingbirds throughout summer. The plant also works beautifully in containers and can be dried for arrangements or fragrant herbal use.

Start seeds indoors 6 to 8 weeks before your last spring frost. Surface sow seeds (they need light to germinate) on moist soil and maintain temperatures between 60 and 75 degrees Fahrenheit. Seeds sprout in 7 to 14 days. Once seedlings develop true leaves, thin or pot them into individual containers and grow them under bright light.
Transplant seedlings outdoors after the last frost date when soil has warmed to at least 60 to 70 degrees Fahrenheit. Harden off plants gradually over 7 to 10 days by exposing them to increasing periods of outdoor conditions. Space transplants 12 inches apart in full sun with well-draining soil.
Direct sow seeds outdoors after the last frost date once soil has warmed. Surface sow seeds where you want them to grow, press gently into moist soil, and keep the area consistently moist until seedlings emerge in 7 to 14 days.
Deadhead spent flower spikes throughout the summer to encourage continued blooming and prevent excessive self-seeding. Cut back the entire plant to 4 to 6 inches in late fall after frost or in early spring as new growth emerges. This rejuvenates older plants and promotes a denser, more compact form.
