Definitions for "Polyantha"
A class of roses derived by Jean Baptiste Guillot from crosses between climbing varieties of R. multiflora and the repeat-flowering China Old Blush. Polyanthas present their delicate flowers in sprays well above their foliage.
Any of a group of early cluster-flowered roses that have not been developed by breeding Hybrid Teas with Polyanthas. Polyanthas generally have small or even tiny roses, but they bear them in large clusters, sometimes managing to completely cover a plant in blossom. They predate Floribundas and are their ancestors; Floribundas having been bred from Polyanthas and Hybrid Teas.[4
Roses too short to notice, really.
