Rosybee Research Findings 2016 update: Which ‘bee-friendly’ plants attract the most bees?


For the last 3 years we have been systematically counting which plants attract the most bees: this report provides an update with the 3rd years worth of data.  

Note: These findings build on the context and method described in the 2014 research paper.

The scope of the 2016 study included 58 plants; 13 native and 45 non-native taking the total number of plants studied, to date, to 79 of which 59 have 2 or 3 years of data

In 2016 the wet and windy spring weather meant that bees were not observed foraging until mid-May (nine weeks later than previously). However, the overall findings are very similar to the averages of the previous two years indicating:

·       Repeating the research annually is beginning to provide consistent metrics

·       Both plants and bees are very resilient to adverse weather events

The chart below shows the top 30 best performing plants over 3 years. The rating for each plant is calculated as: average bees per square meter of the plant x number of weeks that plant flowered.


This year’s study produced findings that mainly reinforced those of the previous years:

·       The primary finding is still that plants are not equally attractive to bees, even when you focus on ‘bee-friendly’ plants, and the variation is significant for anyone wanting to maximize the amount of bee-food that any area of land can provide.

·       Healthy plants with more flowers attract more bees: the old gardeners adage of ‘right plant for the right place’ is important, not only for a sustainable garden, but also for the direct impact on the pollinators each plant may support

·       Generally native and non-native plants continue to appear equally attractive to bees and, except where some specific bees and plants have a more unique inter-dependency; most bees do not care about the origin of the plant as long as the plant’s structure allows them to reach the nectar or pollen.
