(=‘TNTNW’) Meadow-rue is an exceptionally beautiful perennial that shines in a moist woodland setting. Plants have delicate, lacy blue-green foliage a little bit like a Columbine or Maidenhair Fern in effect. This selection from the NIMBUS™ series features cloud-like sprays of white flowers on dark stems. The white flowers mature into lavender pink seed heads extending the showy season. Despite the delicate appearance, it is fairly tolerant of warm, humid summers. Blooms the first year, but much better after a winter chill. In cool regions plants will tolerate full sun if kept moist. Clumps may be easily divided in spring or fall. USPPP: unlicensed propagation prohibited.
