A. ptarmica. - Sneezewort. - This is a desirable border flower, particularly the double variety, as it continues in bloom most of the season, throwing up a succession of its double white flowers in corymbs, on stems about one foot high. The foliage is dark shining green. It is very hardy, and easy to cultivate in almost any common soil.
A. aurea, or golden-flowered, has rich yellow flowers, but not so hardy as the last.
We have a native species, A. millefolium, known by the common name of Yarrow; of this I found a variety with pink flowers, which is now in my possession, and is desirable in a collection.
