How to Grow
Light: Grows well in morning sun to full shade, in all but the driest of spots. It will need moist soil in hot afternoon sun, or the leaves will burn, but in the shade, occasional water is sufficient.
Water: Moderate, prefers even moisture.
Spacing: 26 - 36" apart.
Fertilizing: Grow in well-drained soil that is moderately fertile and humus-rich. We do not recommend fertilizing at planting time or during the first growing season. If desired, a light scattering of slow-release fertilizer in spring should be sufficient for annual maintenance.
Winterizing: Keep old foliage over winter to protect crowns and cut back in early spring.
Maintenance & pruning: If foliage turns black or gets crispy and brown on the edges, this indicates it is in too much sun. It can survive but will look unsightly and should be moved.
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.
