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:

DescriptionSummerific ‘Evening Rose’ perennial hibiscus (aka rose mallow or Hibiscus moscheutos) from Proven Winners combines vivid rose-pink flowers with dramatic deep purple foliage to create one of the most stunning plants you have ever seen. The show begins in mid-summer and continues for weeks, creating a super-colorful display that will grab your attention and capture your heart. One plant on its own is fabulous; planting three or more for a hedge or large group will create a remarkable impact in any sunny spot.
Summerific hibiscus from Proven Winners are herbaceous perennials, so unlike their close cousin rose of Sharon, they die back to the ground in fall and begin each year fresh in spring. They are one of the latest perennials to emerge in spring, but watching them transform from tiny buds to big, healthy plants in a matter of weeks is nothing short of delightful. These are great plants for beginners – anyone, really!DetailsBotanical name:Hibiscus x 'Evening Rose' Patent: USPP 33366 Common name: Hibiscus, perennial hibiscus, hardy hibiscus, swamp mallow, rose mallow, dinner plate hibiscus Zone: 4 - 9 Sun exposure: Full sun (> 6 hours sun) Height x width: 4' tall and 5' wide Flower color: Pink Foliage color: Purple Season of interest: Summer Bloom time: Midsummer, late summer Features: Rain gardens, proven winners, heat tolerant, deer resistant, cold tolerant Uses: Flower gardens, landscaping, specimen, flowering hedge How To GrowSoil: Plant in any sunny spot.
