Hybrid Perpetuals.
Helen Keller (A. Dickson & Sons 1895). — At its best this is a very beautiful Show Rose. In a favourable season it would often be among the three or four most noteworthy H.P.s, in the large stands of the leading nurserymen. Not of very strong growth, "moderately vigorous" representing it fairly. The blooms are of the ordinary "semi-globular" shape, very regular and seldom malformed, of a very bright shade of pink catalogued as "rosy cerise," fragrant, full-sized, with stout petals and good lasting qualities. The buds form early, with frequently fatal results in low lying districts subject to very cold May nights: it is only in exceptionally good seasons that any but the longer later shoots yield good blooms with me: but the variety is well worth growing if only a few fine specimens can be secured.
