Limited Supply. Wild Baby’s Breath, a prairie native, is hard to find but not hard to grow. Sprays of many small, white flowers on 2-3′ stems appear in mid-late summer, and plants self sow where happy. We have found that older plants are not happy about being dug and transplanted, but if you can gather the seedlings when small enough and handle them delicately, you can move them about. Best where they can self sow! Grow in sun and well drained soil.
