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:

There was a heat wave when these plants were shipped and they're not looking good. Despite writing to customer service several times, I'm expected to wait and see for another couple weeks if these browning plants (that I have to trim daily because it's getting more brown as each day passes) will come back to life again. I'm very disappointed. I was going to use these in mixed containers in front of my house, but their appearance is nothing like what is pictured on this page.

Garden Plants has grown well, and this Blue Arrows Rush has taken right off. They were much bigger than I expected and exceptionally well packaged. It been a couple of months, and they look like they've been growing all year. They're lovely companions to my sedums and dianthus. Very happy customer for life here. Thanks!

can they handle brackish water?
Hi there! 'Blue Arrows' Rush is a versatile perennial that can grow in wet conditions, even standing water, however brackish water may not be the ideal environment for it to thrive
I have blue arrow juncus growing in pots on my patio. should I cut them back each year? If so, how far and is it too late to do this now at the end of march.
It may a good idea to trim the plants every few years to increase its vigor. You can cut the perennial down in late spring before new shoots appear. If you're seeing new growth already, you can wait to do this next year.

You can leave them standing through winter, but cut any foliage to the ground in early spring just before the new shoots appear.
