How to Grow
Light: Sun (> 6 hours sun). Best flowering occurs in full sun locations. Stems are more likely to flop if plants are grown in part shade.
Water: Dry to medium. Water regularly until established.
Spacing: 2ft apart.
Fertilizing : Generally unnecessary but can be applied in spring if needed.
Winterizing: No special care is needed. Foliage can remain standing in the winter.
Maintenance & pruning: Cut back plants almost to the ground in late winter to early spring as soon as new growth appears. Plants have deep taproots and don't like to move once established.
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:
