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 Glow' globe thistle (or Echinops bannaticus ) may have unconventional flowers, but that's what makes it so charming! Perfectly spherical tufts of blue flowers bloom in summer on tall, unbranched stems, resembling a mini solar system in the landscape. Bumblebees enjoy the flowers, but nocturnal moths find them especially delightful. This perennial is best planted in poor soils with full sun and steep drainage, so it will easily grow in rock gardens or troublesome sites. Since it's drought tolerant, deer and rabbit resistant, and easy to grow, we recommend it for gardeners of any level.
