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'Sassy Summer Taffy' yarrow (or Achillea) may not be edible for humans, but it sure is a sweet treat for pollinators. Dark salmon florets bloom continuously through summer, turning a light peach as the flowers age. The flowers are clustered together to form plush landing pads for pollinators (who visit the flowers constantly). Even with the weight of the largest butterfly, the tall and sturdy stems keep the flowers upright without extra support. It's a great choice for beginners, pollinator lovers, and every gardener in between.
Yarrows have long been used in sunny and dry gardens but have recently resurged among cut-flower gardeners. Yarrows are vigorous growers that bloom prolifically through summer. Extra-long stems and fragrant clusters of flowers are ideal for cut arrangements (fresh or dried). Fresh flowers have an expected vase life of 5-7 days, but dried flowers can be enjoyed for weeks. Plant them in full sun and well-draining soil, and they'll reward you with continuous blooms and a sunny disposition.DetailsBotanical Name:Achillea 'Sassy Summer Taffy' Patent: PP31,755 Common Name: Yarrow Zone: 3 - 8 Sun Exposure: Full sun (>6 hours/day) Height x Width: 26-32" x 22-26" Flower Color: Shades of pink Foliage Color: Silver green Season of Interest: Summer Bloom time: Early to late summer Features: Rabbit resistant, proven winners, low flammability, heat tolerant, deer resistant, cold tolerant, best for beginners Uses: Edging, flower gardens, wildlife gardens, native plant gardens, cut flower gardens, rock gardens, containers How To GrowSoil: Thrives in any well-drained, even dry, soil. Light: Full sun (6+ hrs/day) Water: Average to low soil moisture. Avoid moist or wet soils, which can lead to weak growth and rot. Spacing: 2-3 feet Fertilizing: Not required or recommended. Overly fertile soils or conditions encourage floppy growth. Winterizing: No special winter requirements; dry conditions in winter are preferred. Maintenance & Pruning: Plant can be cut back after its first early summer bloom for a flush of fresh growth as with other yarrow. However, this is not strictly necessary, as this improved selection continues to bloom without the customary trim.
