Rosa rugosa JAM-A-LICIOUS (PBR) is a deciduous shrub bred for its combination of strong flowering, distinctive fruiting, and resilient growth rather than refined bloom form. It produces single, open flowers in rich pink tones through summer, followed by large, rounded hips that swell and colour as the season advances, giving the plant a second phase of interest well into autumn. The foliage is thick and textured, forming a dense framework that copes well with exposed conditions and poor soils. Growth is robust but not unruly, creating a substantial shrub that holds its shape without frequent intervention. Practical, tough, and visually effective beyond the flowering window, JAM-A-LICIOUS suits informal borders, wildlife planting, and coastal or challenging sites where reliability and seasonal change matter more than delicacy.
