This common name is given to Exo-chorda grandiflora and also to E. Alberti, which are closely related species. The latter species from Turkestan thrives best in the prairie States, and in all parts, so far as known to the writer, the Alberti is most vigorous in growth, has darker foliage, and its pure white flowers show on longer spikes than those of the grandiflora. By pruning it can be kept in good shape, but it has most value when massed with other shrubs, where its irregular habit adds to the variety of expression. The grandiflora as yet is the common variety of the nurseries.
