Shape

• Experiments show that flowers with long, flexible stems, such as the Sea Campion of West Wales, attract more bees by swaying in the breeze more easily than short-stemmed flowers. Also, flowers with large, accessible blooms ensure that bees are able to reach nectar easily, while picking up pollen in the process.
  
  

Fragrance

• Flowers with stronger scents than their competitors have a better chance of attracting bees for pollination.
  
  

Native Flowers

• In one experiment, bumblebees showed an innate attraction to native flowers that produced the most nectar. In this case, violet flowers produced the most nectar, followed by blue ones.
  
  

Iridescence

• Iridescence occurs when a surface has the ability to change color when viewed at a different angle. Research shows that bees are attracted to a flower's iridescence as well as its color. Scientists have identified iridescence in hibiscus and tulip flowers, but suspect that it is a widespread characteristic.
  
  

Benefits and Risks

• Bees can benefit the health of any garden. However, young children and individuals who are allergic to bee stings should be cautious in areas where bees may live or forage.
