How to Grow
Light: Sun (>6 hours sun). Full sun is best in the North. It is somewhat intolerant of the deep South's heat and humidity and appreciates some afternoon shade in hot climates.
Water: Dry to medium
Spacing: 28-30"
Fertilizing: In average soil, needs almost no fertilizer. Too much fertilizer will only make it grow lots of flimsy foliage. Some compost in poor soil in fall or spring or a very light scattering of slow-release fertilizer in early spring will provide sufficient nutrients to keep the plant happy.
Winterizing: Leave spent foliage in place over winter to help protect the crown. Wait until early spring to cut it back.
Maintenance & pruning: Shear flower spikes after initial flowering to promote continued bloom. Can shear plant foliage for a fresh flush in late summer.
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:
Not sure just how many plants will fit in your garden? Our calculator gives you the exact amount of plants required for your space. Simply update the values and the calculator will re-calculate accordingly. Spacing information can be found in the 'How to Grow' tab on each plant's page.
