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:

DescriptionNothing else says simple class like stunning white flowers. 'Opening Act White' phlox is full of it! Blooming earlier than typical tall phlox varieties, 'Opening Act White' will fill your garden with its pure white blooms and the pollinators that flock to them from early summer well into mid-summer. If spent flowers are sheared back, there will be sporadic rebloom into fall. This upright, clumping garden phlox looks handsome in cottage gardens, container displays, and especially in flower arrangements. You won't have to worry about unsightly leaves dampening the display because its dark green foliage remains attractive throughout the season due to fantastic disease resistance and heat tolerance.DetailsBotanical name: Phlox 'Opening Act White' Patent #: USPP 27,461 Common name: Hybrid garden phlox Zone: 4 - 8 Sun exposure: Sun (> 6 hours sun) Height x width: 18-20" X 18-20" Flower color: White Foliage color: Green Season of interest: Early summer to fall Bloom time: Early summer, midsummer, late summer Features: Rain gardens, proven winners, native, cold tolerant, fragrant Uses: Background, border, cottage gardening, massing, specimen, wildflower
