floriferousness

Health, floriferousness, scent and commercial appeal are all considered key factors.

Rose trial grounds or rose test gardens are agricultural areas where garden roses are grown to be assessed for qualities such as health, floriferousness, novelty, and scent.

The shrubs are presented alphabetically, but at the back of the book you'll find a truly awesome set of appendixes breaking down the cultivars by hardiness zone, shade tolerance, pest and disease resistance, fragrance, floriferousness, soil preference, environmental stress resistance - everything but deer-withstanding ability.
