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:

DescriptionSparky® Blue Clematis (Clematis sp.) is not your typical clematis - not by a long shot! This easy-growing spring bloomer creates boatloads of unusual pinwheel-like flowers, each one a spiky mass of beautifully colorful petals. They're accented perfectly by the delicately toothed foliage. Sparky Blue clematis is a vining type, but it's far more restrained than other clematis and needs only a light decorative trellis to grow on. Or let it interweave itself in an arborvitae or other evergreen for a hint of color.
Though it blooms mainly in spring, it continues to create additional flowers throughout the summer in Michigan. Because this type blooms early in the season, no special knowledge or pruning is necessary to take care of it - simply let it do its thing and remove old stems every few years as needed. Colorful, fun, easy to grow: this is a clematis that definitely sparks joy!DetailsBotanical name:Clematis 'Zospi' Common name: Clematis (Atragene group) Zone: 5 - 8 Sun exposure: Sun (> 6 hours sun) to part sun (4-6 hours sun) Height x width: 6-8' x 2' Flower color: Purple Foliage color: Green Season of interest: Early summer-fall Uses: Container gardening, Cottage gardening, Vines and climbers How To GrowSoil: Well-drained soils are essential for success with clematis. They have big, thick, fleshy, rope-like roots that also benefit from loose soils, which can make clay problematic. They do prefer neutral to slightly alkaline soils but ultimately, good drainage is far more important than "proper" pH. Light: Full sun to part shade. The old saying for clematis is, "Feet in the shade, head in the sun," so its best if the vines get plenty of sunshine but the roots stay cool and shaded, either with neighboring plants or mulch. Water: Average Spacing: Because they are vines, spacing is not as crucial for clematis as for other woody plants. 2-3' apart should be fine in most situations. Fertilizing: fertilizer is not necessary, but you can apply a granular rose fertilizer in early spring if desired. Winterizing: Aside from a 2-3" layer of shredded bark mulch over the roots, no special winter care is required. Plants should be left standing over winter. Maintenance & pruning: Sparky clematis are spring blooming, and should be pruned rarely, if at all. They will continue to bloom in summer unless the weather becomes very hot. Deadheading or pruning is not required. Plants will be generally problem-free provided that drainage is good and roots are never in wet soil or standing water.
