A numerous family of hardy plants spread through Northern Asia, Italy, Greece, Turkey, Hungary, etc., but more in Southern than in Central or Northern Europe. In the Alps and Pyrenees numerous species are found. The Golden Yarrows (A. Eupatorium and A. filipendulina) are stately herbaceous plants, with broad handsome corymbs of brilliantly showy flowers, attaining a height of 3 feet or 4 feet, and growing freely in any soil. These are well worthy of naturalisation. Various other Achilleas would grow quite as well in copses and rough places as the common Yarrow, but we know of none more distinct and brilliant than the preceding. The vigorous white-flowering kinds are superb for shrubberies, where their numerous white heads of flowers produce a singularly pleasing effect under the trees in summer. With few exceptions these plants have never been grown out of botanic gardens, many of them being thought too coarse for the mixed border. They are, nevertheless, remarkably beautiful both in flower and foliage, and many effects never before seen in gardens may be obtained by massing them under trees in shrubberies or copses, as a rule allowing one species to establish itself in each place and assume an easy natural boundary of its own. The small Alpine species would be interesting plants for stony or bare rocky places.
