Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionAre you looking for a long-blooming perennial that doesn’t skimp on the showy flowers? Then Whispurr™ Blue catmint (Nepeta x faassenii) is a must-plant in your landscape! Its gorgeous habit features an array of highly scented tubular blue and purple flowers on sturdy upright stems. You won’t be the only one who loves the soft blue flowers; pollinators like bees, butterflies, hummingbirds, and more can’t get enough of it either. But don’t worry; even though it attracts beneficial pollinators, it also deters deer and rabbits with mint-scented foliage. What’s not to love? Whispurr™ Blue is also an incredibly resilient perennial that can thrive in tough-to-grow sites with prolonged heat, cold, and drought periods. Plant this catmint variety in a sunny spot, and you’ll be surprised at how little maintenance it requires!DetailsBotanical name:Nepeta faassenii 'Balpurrlu' Patent #: PP33,042 Common name: Catmint Zone: 4 - 9 Sun exposure: Sun (> 6 hours sun) Height x width: 24-28" X 18-22" Flower color: Blue-purple Foliage color: Grey-green Season of interest: Summer Bloom time: Summer Features: Suitable for slopes, rabbit resistant, proven winners, heat tolerant, deer resistant, container plants, cold tolerant, best for beginners Uses: Container gardening, cottage gardening, edging, erosion control, ground cover, massing, rock garden, slopes
How To GrowSoil: Easily grown in average, dry to medium, well-drained soil. Thrives in dry soils and is very drought tolerant. Light: Sun (>6 hours sun). Full sun is best in the North. It is somewhat intolerant of the deep South's heat and humidity and appreciates some afternoon shade in hot climates. Water: Dry to medium Spacing: 28-30" Fertilizing: In average soil, needs almost no fertilizer. Too much fertilizer will only make it grow lots of flimsy foliage. Some compost in poor soil in fall or spring or a very light scattering of slow-release fertilizer in early spring will provide sufficient nutrients to keep the plant happy. Winterizing: Leave spent foliage in place over winter to help protect the crown. Wait until early spring to cut it back. Maintenance & pruning: Shear flower spikes after initial flowering to promote continued bloom. Can shear plant foliage for a fresh flush in late summer.
