Identifying a suitable annual floral mixture and its relative attractiveness to pollinators in Central Spain

Abstract: Wildflower strips in crop margins can contribute to the conservation and enhance of pollinators in the crop area. We have tested during 2 years in Central Spain, a mixture of several wild species of different botanical families well adapted to the area. By assessing floral coverage, precocity and duration of bloom and pollinator visits, we conclude that Coriandrum sativum, Diplotaxis virgata, Borago officinalis and Calendula officinalis are the best candidates for a seed mixture for the study area.
