The pick of the plot: An evidence‐based approach for selecting and testing suitable plants to use in annual seed mixes to attract insect pollinators

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Concern regarding wild pollinator declines has increased motivation to plant pollinator‐friendly plants in gardens and urban areas, but ‘plants for pollinators’ recommendations are often anecdotal and inaccurate. Here, we use a scientific evidence base to design and test annual flowering seed mixes for bees and hoverflies.
