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:

DescriptionThe wispy foliage of Palm Sedge (or Carex muskingumensis) is perfect for adding color, texture, and movement to your landscape. Narrow green leaves emerge from the stems in a palm-like pattern, giving it a distinct look. Arching flower spikes appear in summer, and as they fade to seed heads, they're often visited by birds and other wildlife.
Palm sedge is easy to grow - even for beginner gardeners. It slowly spreads through rhizomes in optimal growing conditions. As a native of North American wetlands, it's a problem-solving perennial that can handle wet and shaded sites.
