Pemberton's Roses
A[...] class tending to be hardy, everblooming climbers, originated in England by the Rev. Joseph Pemberton. These are hybrids of Rosa moschata, the Musk Rose, whereas the Lambertianas are Hybrid Multifloras. Captain Thomas’ Roses offered below are similar, partaking of elements from both classes, combined with original traits. These Roses are $1 each for strong, field-grown plants
Galatea. Hybrid Musk. (1914.) Small, rosette-like flowers of stone-color edged with pink; fragrant; blooms in clusters throughout summer and fall.
Particularly good in autumn when the flowers are larger and richer in color.

Galatea (Perpetual Climber).— Like a double form of Moonlight. There does not appear to be any room for a Rose of this description, and those who will plant it will be very limited in number. Roses of this class must be perfectly distinct and attractive to command public attention, and we shall soon be overburdened with them unless discretion is employed by raisers.
