Achillea Ptarmica.

Syns. A. Sylvestris and Ptarmica Vulgaris; Common Names, Wild Yarrow, Sneezewort, Goose-tongue, and Wild Pellitory; Nat. Ord. Compositæ.

A very common British plant, or, I may say, weed, which can[Pg 5] live in the most reeky towns, only mentioned here to introduce A. P. fl.-pl., which is one of the most useful of border flowers. I am bound to add, however, that only when in flower is it more presentable than the weedy and typical form; but the grand masses of pure white bachelors'-button-like flowers, which are produced for many weeks in succession, render this plant deserving of a place in every garden. It is a very old flower in English gardens. Some 250 years ago Parkinson referred to the double flowering kind, in his "Paradise of Pleasant Flowers," as a then common plant; and I may as well produce Gerarde's description of the typical form, which answers, in all respects, for the double one, with the exception of the flowers themselves: "The small Sneesewoort hath many rounde and brittle braunches, beset with long and narrowe leaues, hackt about the edges like a sawe; at the top of the stalkes do grow smal single flowers like the fielde Daisie. The roote is tender and full of strings, creeping farre abroade in the earth, and in short time occupieth very much grounde." The flowers of this plant are often, but wrongly, called "bachelors' buttons," which they much resemble.

For cutting purposes, this plant is one of the most useful; not only are the blooms a good white, but they have the quality of keeping clean, and are produced in greater numbers than ever I saw them on the single form. Those requiring large quantities of white flowers could not do better than give the plant a few square yards in some unfrequented part of the garden; any kind of soil will suit it, but if enriched the bloom will be all the better for it. The roots run freely just under the surface, so that a large stock may soon be had; yet, fine as are its flowers, hardy and spreading as the plant proves, it is but seldom met with. Even in small gardens this fine old flower should be allowed a little space. Transplant any time.

Flowering period, June to August.
