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:

Description'Blue Fortune' hummingbird mint (or Agastache) boasts lavender-blue flowers, fragrant foliage, and an impressively long bloom time - which is why we're not surprised it's an award-winning perennial. Bottlebrush flowers attract pollinators from midsummer to fall, adding interest to the late summer garden as other perennials start to fade. Though it's similar to 'Blue Boa' hummingbird mint, 'Blue Fortune' has lighter blue flowers.
The mint-like foliage of hummingbird mint is pleasant to humans but is unbothered by deer. It's tolerant to hot, dry sites and performs exceptionally well in containers. Plant it in an area with full sun and high drainage, then watch it thrive.DetailsBotanical name:Agastache 'Blue Fortune' Common name: Hummingbird mint, anise hyssop Zone: 4 - 9 Sun exposure: Sun (> 6 hours sun) Height x width: 24-36" x 18-24" Flower color: Blue and purple Foliage color: Green Season of interest: Summer to fall Bloom time: Summer Features: Rabbit resistant, native, low flammability, heat tolerant, dry soils, deer resistant, best for beginners Uses: Edging, flower gardens, wildlife garden, cut flower, attracts hummingbirds, pollinator garden, wildflower garden, bordersHow To GrowSoil: Thrives in any well-drained, even dry, soil.
