Sow indoors 8 weeks before last frost and keep at 60-70F. If no germination after 3-4 weeks cover pots with plastic and chill in refrigerator for 2-3 weeks, then bring into warmth.
Recommended. Direct sow in fall or earliest spring into a prepared seedbed.
PLACEMENT & CULTIVATION
An airy "see-through" plant with lacy foliage and soft pink flowers blooming atop sturdy stems. A branching habit results in loads of flat-topped blooms in summer, drawing beneficial insects and butterflies of diverse kinds. Outstanding in meadow plantings in large drifts or along ponds, it also is a graceful addition to the mid or back border.
Keep moist but not soggy—at least 1" of water per week during dry spells.
Not particular about soil pH.
Incorporate a couple of inches of compost prior to planting. If soil is especially poor, further amendments with organic matter may be necessary.
When to Cut for Bouquets:
