This is a beautiful large-flowering variety of A. Alpina, which, from its immense distribution, will soon become a familiar plant. It is of very free growth, resembling the common Thrift, but much larger both in foliage and flowers, and continues in bloom for seven or eight months out of the twelve. Some two years ago it was highly spoken of by several writers in the 'Gardener's Chronicle,' certainly in no higher terms than it deserves. This variety will be found very useful in furnishing a stand of cut flowers of hardy perennials and herbaceous plants.
