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:

DescriptionA twist on the ordinary phlox subulata, 'Rose Sprite' grows in a low, tidy mound instead of spreading out. Its star-shaped flowers are a lovely shade of light purple and arrive a week or so later than other varieties, extending the flowering season nicely. This variety can handle a little more shade than others and looks nice when planted with spring-flowering bulbs. As a native, it is pretty resilient and can adapt to slightly acidic, poor, or dry soils.DetailsBotanical name: Phlox 'Rose Sprite' Patent #: USPP 31,214 Common name: Hybrid spring phlox Zone: 3 - 8 Sun exposure: Sun (> 6 hours sun) to part sun (4-6 hours sun) Height x width: 6-8" x 18-22" Flower color: Pink with white halo centers Foliage color: Green Season of interest: Summer Bloom time: Midspring, late spring Features: Proven winners, native, ground covers, cold tolerant, best for beginners Uses: Alpine and rock, container gardening, butterfly garden, edging, ground cover, rock garden, small spaces, native garden, pollinator gardenHow To GrowSoil: Performs best in well-drained soil.
