Shower of Pearls Rose (Dwarf)
This rose belongs to a distinct class of tiny roses, called Polyanthea hybrida plena. The Cecil Bruner and others of its class are Polyanthea roses, but “Shower of Pearls” is a miniature rose, with small foliage rarely growing more than two feet high. It is an exquisite snow-white single rose that grows in lovely sprays with round wide open flowers like showers of pearls, over the plant. It has a most dainty delightful fragrance, reminding one of early spring flowers and is unlike any other rose ever before offered. 25c.
