How to Grow
Light: Sun (> 6 hours sun) to part-sun (4-6 hours sun). Afternoon shade is beneficial in warmer climates.
Water: Average water needs. Prefers consistently moist, but not wet soil.
Spacing: 5 -8 inches
Fertilizing: Generally unnecessary is average to rich soils. A spring application of slow-release fertilizer, such as osmocote, can be applied if desired.
Winterizing: Many perennials will grow new leaves around the base of the plant after flowering. These should be left on the plant in the fall, as they protect the crown. Clean off old foliage in early spring as new growth emerges.
Maintenance & pruning: Will continue blooming for weeks if spent blossoms are regularly removed. Plants should be divided every 2 to 4 years, in spring or fall. A summer mulching is important to keep the roots cool.
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:
