Plant dedicated floral resources on farmland Bee Conservation

Tuell et al. (2008) evaluated native perennial plant species in the eastern USA for their attractiveness to wild bees in a replicated experiment (five replicate 1 m2 plots of each species). Nine out of 43 species were highly attractive to bees, having an average of five or more wild bees per m2 plot in vacuum sampling or timed observation. These were Potentilla fruticosa, Scrophularia marilandica, Veronicastrum virginicum, Ratibida pinnata, Agastache nepetoides, Silphium perfoliatum, Lobelia siphilitica, Solidago riddellii and Solidago speciosa. Three other plant species (Zizia aurea, Fragaria virginiana and Coreopsis lanceolata) were identified as attractive to wild bees in the early season (May and June), a crucial time for early-emerging bee species, when flowers are generally less abundant.
