Spiræa Venusta
Queen of the Prairie; Nat. Ord. Rosaceæ.
A comparatively new species of the herbaceous section, from North America. In good deep loam it grows to the height of 3ft. or more.
The flowers are of a soft red, after the manner of those of S. palmata, but rather differently arranged, viz., in clustered sprays or cymes, which bend outwards; they are durable and very effective, even when seen at some distance in the garden, whilst for cutting they are flowers of first-class merit; the leaves are large, somewhat coarse, pinnate, segments sharply lobed and irregularly serrated.
I find this plant to flower indifferently under the shade of trees, but in a fully exposed situation, planted in a deep retentive loam, it thrives and flowers well. It is perfectly hardy, and easily propagated by division during autumn.
Flowering period, June to August.
