How to Grow
Light: Full sun (>6 hours sun) to part-sun (4-6 hours sun)
Water: Prefers to grow in wet soils. Do not let the soil dry out.
Spacing: 1 foot
Fertilizing: Fertilizer is generally unnecessary, but if your plant looks deficient or is growing slowly, apply a slow-release fertilizer. If you are planting near bodies of water, be careful when choosing fertilizers.
Winterizing: Semi-evergreen in warm climates. Cut back foliage before winter in colder climates.
Maintenance & Pruning: About every 3-4 years, propagate by division of the clump into several pieces in early spring (after shearing the dead foliage away) and discard the center of the clump (and any other peripheral portions which have died).
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:
