For restoration purposes nature conservation preferably requests the use of local seed sources based on the “local-is-best” (LIB) approach. However, counter-arguments against this usage are potential benefits by increased variation, which could be beneficial especially in times of global change. We here investigate intraspecific morphological variability of one of the most common herbaceous, insect pollinated and zoochorous plants from seed mixtures used for landscape restoration processes in central Europe, the wild carrot, Daucus carota L. (Apiaceae). Our results show that D. carota features no vegetative but two generative characters that significantly differed among plants originating from seeds of natural (I) and restored (R) sites. We could show that effects of mowing always overlay origin-specific characteristics. The earlier genetic analysis did not support a regional provenance concept for restoration purposes, while slight differences in phenological parameters related to fitness pinpoint to ‘mix and match-admixture provenancing’ as a compromise strategy.
