Dioressence® – purple bedding floribunda rose – Delbard & Delbard-Chabert
If You dream of a romantic front garden with perfume drifting from richly coloured blooms, Dioressence® is made for You. This floribunda bedding rose combines intensely fragrant flowers with reliable repeat flowering, so Your beds and borders keep their charm well beyond the first flush. Its bushy, upright habit forms a neat shrub that fits comfortably into the average Irish family garden, coping well with our moist weather and the kind of humidity that often encourages fungal problems. Own-root plants settle in steadily, building a long-lived, resilient framework that regenerates well after pruning and supports many seasons of bloom. In year one the roots establish, in year two top growth and flowering build up, and by year three You enjoy its full impact as a mature, well-shaped rose. Whether used for cut flowers in the house or to anchor a cottage-style border outdoors, Dioressence® offers dependable, easy-to-manage elegance for beginners and enthusiasts alike.
