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:

DescriptionCreate a dazzling summertime display with ‘Purple Emperor’ (Echinacea hybrid). This tidy coneflower keeps its good looks all summer long with no straggly stems in sight, just sturdy stems and big saturated blooms. Coneflowers are a garden staple for a reason; their cheery fragrant flowers are beloved by pollinators and remarkably easy to care for.
‘Purple Emperor’ boasts a summery shade of magenta. Not quite purple, but still very eyecatching, especially when planted as a border or in masses. This sun-loving perennial is the perfect way to add low-maintenance color to your garden.DetailsBotanical name:Echinacea x 'Purple Emperor' Patent #: USPP 24,459 Common name: Coneflower Zone: 4 - 8 Sun exposure: Sun (6+ hours sun), Part-sun (4-6 hours sun) Height x width: 15-18" x 12-16" Flower color: Magenta Foliage color: Green Season of Interest: Summer-fall Bloom time: Midsummer, late summer: Features: Native, heat tolerant, drought tolerant, deer resistant, best sellers, container plants Uses: Border, cottage gardening, massing, naturalizing, specimen, wildflowerHow 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 - 22 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.
