Achillea X kellereri
Yarrow, White Daisy
Description
The white colored, flat-topped flowers of this plant are visible on the mats it forms, which have a gray green, wooly appearance with leaves that are similar to those of a fern. The yarrow propagate easily from rooted cuttings or division, which should be performed in the early spring or fall. Following bloom, one should dead head the plant and divide the clumps when it appears crowded.
