Moss Roses
All Moss Roses are 75 cts. each, $6.50 for 10, for strong, field-grown plants
Moss Roses are forms of the Cabbage Roses which bear a crown of lacy moss upon the stems and sepals. They are exquisitely lovely in bud. Absolutely hardy. They should be given good soil and careful attention to bring out their best qualities, but they live and produce fair blooms when completely neglected.
Baron de Wassenaër. (V. Verdier, 1854.) Light crimson, globular flowers, not fully double, and of more than average size, blooms in clusters. Vigorous growth.
