Prunus spinosa  is a highly esteemed shrub in forest and landscape plantings. Shrubs with larger organs occur often and are considered either as large fruited forms of  P. spinosa  or as  P. x fruticans , involving a hybridization process with the ancient cultivated  P. insititia  (crop-to-wild gene flow). As climate change may augment hybridization processes in the future, a hybrid origin is important to detect. In addition, studying crop-to-wild gene flow can give insights in putative consequences for the wild populations. We studied the  P. spinosa – P. x fruticans  group, focusing on morphology and phenology in three experimental plantations. Two plantings harbored cuttings of  P. spinosa  (clone plantations). A third plantation comprised of a half-sib offspring from a population with both  P. spinosa  and  P. x fruticans  (family plantation). Several results point to a hybridization process as the origin of  P. x fruticans . The clone plantation revealed endocarp traits to be more genetically controlled than fruit size, while this was the opposite in the family plantation, suggesting the control of fruit size being derived from the putative  P. insititia  parent. Bud burst, flower opening, and leaf fall were genetically controlled in the clone plantation, whereas in the family plantation intrafamily variability was remarkably large for the bud burst and leaf fall, but not for the flower opening. This suggests there is a reduced genetic control for the first two phenophases, possibly caused by historic hybridization events. Pubescence on the long shoot leaves in the family plantation deviated from the short shoot leaves on the same plants and from long and short shoot leaves in the clone plantation, suggesting again a  P. insititia  origin. Finally, we quantified spatial phenotypic plasticity, indicating how  P. spinosa  may react in a changing environment. In contrast to the bud burst and leaf fall, flower opening did not demonstrate plasticity. The fruit size was diminished at the growth site with the shortest growing season while interestingly, the leaf width was enlarged. Leaf size traits appeared more plastic on the long shoots compared to the short shoots, although partitioning of variance did not display a lesser genetic control.
