It is so great to see that our study may be put into practice and that we managed to write the paper in accessible and comprehensible way (and this is is really difficult, especially for non native English speaker). Thank you!.
Please take a look at the Table 7 ( http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0183236#pone-0183236-t007 ) in our paper ( http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0183236#pone-0183236-t007 ), where we presented 85 plants, that were investigated during last 75 years of bee research and we calculated which plants may limit bee growth and development (negatively influencing health and condition, resulting in underdevelopment or even in death) and which plants produce pollen nutritionally balanced for bees, therefore promoting their development and health. In case of Europe, clover, producing pollen nutritionally balanced for bees, is a good choice as bee-friendly plant. You may find something else for yourself. We found that lavender produce highly nutritionally imbalanced pollen, therefore even if considered as bee-friendly, because of nectar production (source of energy but not physiologically important nutrients) and even if lavender attracts pollinators to a high degree, its good to provide the insects with another source of pollen that is nutritionally balanced and enables gathering of important nutrients in needed proportions. In general we suggest that plants should not be evaluated as adequate sources of bee food based solely on the quantity of pollen produced. The nutritional quality of pollen should also be taken into consideration.
