The Great Sunflower Project – The Backyard Bee Count

The Great Bee Count

Within the past couple of years, you might have heard that bees are in trouble, growing scarcer, and suffering from a mysterious ailment called Colony Collapse Disorder, or CCD. A variety of culprits have been fingered in causing this syndrome, including pesticide use, parasites, loss of habitat, and diseases. To study bees, both native and the non-native honeybee, scientists decided that they needed a method to determine the numbers and spread of different pollinators. To accomplish this, in 2008 a survey was launched enlisting and empowering local citizens in reporting observations about bees in their own backyard or deck called The Great Bee Count.

Citizen Science



The Great Bee Count, recruits citizens across the United States and Canada to plant sunflowers and observe all types of bees visiting the flower in a 15 minute time period daily for a week and record their findings on-line.  The first Great Bee Count took place about 7 years ago and countless volunteers recorded their findings to help scientists to check on the prevalence of our tiny pollinators in North America.

The data is called ‘trend data’ and showed that in some parts of the country the bees are doing very well, but in other parts like Florida where pesticide use is widespread, the bees are not nearly as numerous. I participated last year and counted at least a dozen bees on my sunflowers in a 15 minute period daily in my backyard in Maryland which shows that this part of the country is above average ‘bee friendly’!

Now is the time to order those seeds and get your garden ready to plant your sunflowers. Lemon Queen is the preferred variety of sunflower seeds. It is important to check to make sure that the seeds did not receive a neonicotinoid seed treatment or even better, are organic.  The Great Sunflower Project recommends that people look for Renee’s Garden Seeds because they have partnered with Renee for a number of years and she has offered to pass along 25% of her proceeds from seeds bought at her website to the Great Sunflower Project.

The typical observer saw 2.6 bees every 15 minutes on their sunflowers. Up to 20% of the volunteers observed no bees at all which is very disheartening. Sunflowers were chosen as the standardized plant because they are ‘bee magnets’ and are easy to grow in every state. ‘Lemon Queen’ is the preferred variety because some sunflowers have been developed that have no pollen, but ‘Lemon Queen’ has visible pollen. Even if the grower did not observe bees during the 15 minute interval, that information is valuable also in informing scientists. Keeping tabs on our bees has become an important tool in studying this essential aid to our food supply. Up to one-third of our food supply relies exclusively on bee pollination.

Anyone in North America can participate in The Great Bee Count even if you just have a single container planted outside on a balcony or deck. To find out how to sign up, go to, register, and plant your sunflower seeds so you can start counting this summer! This is a great project for an ordinary person to have help out the scientific community to study our local bee populations.


I would love to hear from people who are not in North America to see if there are any similar projects in their country.  Please let me know if you have heard of any or participated.

Don’t forget that there are many plants that you can plant to encourage bee visits. Go to Plant For the Bees post to see more suggestions.

  1. Many thanks for sharing such great information about ‘The Great Bee Count!’ I’m looking forward to participating this summer and will plant sunflowers in my Illinois garden. With your permission, I would love to reblog this wonderful post. I’m really enjoying your blog, Claire! ♡

  2. I’m planting 3 different varieties of sunflower this year. Had no idea some of them didn’t produce pollen. Is there a way to tell if they do or not? My bees love chive flowers. I usually cut them off before they flower but decided to leave them on because I know they like it. 🙂 I have several other things growing in your list so I think my new bees will be happy in my yard.
