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:

We planted one plant and got two swallowtail caterpillars very soon. Fun to watch them grow!!
It’s healthy and happy!
I am between zone 4-5b and we planted the rue in full sun in a very stable mature bed. It started out with a few yellowing leaves and it has not settled in yet. It has been a month and it still looks like it did when we planted it. There has been no growth or dying off, it is exactly the same size it was when it came out of the box. We buy a lot of plants on line and GreatGardenPlants has a very good track record with us. Their shipping and packing is excellent.
We have not given up hope and we want to give the rue it a few more weeks. It looks fine, but it hasn't "taken" to the earth in any noticeable way. One of nature's little mysteries.
