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:

DescriptionWith nearly every color of the rainbow packed into a single plant, SunSeekers® 'Rainbow' coneflower (or Echinacea) will surely make a statement in your garden. Flowers bloom in early summer with light yellow petals, and as they mature, they pick up pink, blush, orange, and even lavender hues. The color-changing petals are packed around a dark bronze center, often visited by pollinators. It continuously produces flowers through the summer, which means there will always be a variety of colors to enjoy.
Coneflowers are native perennials beloved by gardeners for their cheery flowers, pollinator-attracting power, and easy-growing nature. Their flowers attract bees and butterflies, and after they fade, seedheads provide food for birds through the winter. Since they're drought tolerant, deer resistant, and durable, they are easy to enjoy by gardeners of any level. DetailsBotanical name:Echinacea ‘SunSeekers Rainbow’ Patent #: USPPAF Common name: Coneflower, echinacea Zone: 4 – 9 Sun exposure: Sun (6+ hours sun), Part Shade (4-6 hrs. Direct Sun) Height x width: 18-24″ x 12-18″ Flower color: Pink Foliage color: Green Season of Interest: Summer-fall Bloom time: Summer, fall Features: Proven winners, native, low flammability, drought tolerant, deer resistant, container plants, best sellers, best for beginners Uses: Border, cottage gardening, massing, naturalizing, pollinator plant, native plant, wildflower.How To GrowSoil: Any well-drained soil will do. Light: Full sun. Plant them in a spot that gets at least 6 hours of full sun a day. If planted in too much shade, plants may flop or strain to reach the sun. Water: Average. Water regularly the first season to encourage good root growth. Though coneflowers handle heat and dry conditions well once established, they appreciate regular watering and flower more if they are not stressed. Spacing: 16 – 20 inches Fertilizing: Little needed. Over-fertilizing will cause spindly growth, so once in the spring with a granular garden fertilizer is more than sufficient. Winterizing: Avoid damp spots. Do not heap mulching over crowns in winter, as this can cause rot. Leave the foliage and old flowers standing for winter (birds enjoy the seed heads), then trim back or remove spent foliage in early spring before new growth emerges. Maintenance & Pruning: Once planted, they are best left alone, as they do not transplant well. Deadheading (snipping off the spent blooms) is not necessary but does increase new flower production.
