Plant Spacing

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:

bush distance

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:

Same scenario as the 5/4/25 review but I planted in the spring of 2024 and they filled up a space of 18x18" by fall! Off and running but nothing at all showed up this spring. 😩 Zone 5. Sooo disappointed.

Did not last a single winter

All plugs died over winter. Zone 7a. Expensive and disappointing.

Jury’s still out

The jury is still out on how the plants that got planted will perform. The 2-star rating is because four of the middle plugs had “dissolved” into nothing but potting soil. I wasn’t going to complain, but you asked...

The juries out

Plants arrived looking beautiful and healthy. Since planted, they haven’t done much, even though my husband has tended them like newborn babies. We are hopeful they are just a little stunted from the move.
