The Boursalt roses are remarkable for their profusion of flowers, and for their shining, reddish stems, with few thorns. The common Purple or Crimson Boursalt is quite a wonder of beauty in the latter part of May, when trained on the wall of a cottage, being then literally covered with blossoms; and it is so hardy that scarcely a branch is ever injured by the cold of winter. The Blush and the Elegans are still richer and finer varieties of this class of roses, all of which are well worthy of attention.
