Bee Keeping Course: Session III – Managing the Colony. Nectar & Pollen Plants of Illinois. NECTAR. Nectar is a sweet liquid (mostly sugar and water) made in special glands called nectaries that are found on flowering plants. Necatries are most often found by the base of a flower’s petals.

nectar
NECTAR
  • Nectar is a sweet liquid (mostly sugar and water) made in special glands called nectaries that are found on flowering plants.
  • Necatries are most often found by the base of a flower’s petals.
  • Nectar is the reward given to

insects and small animals

for their help with pollination.

  • Nectar is the base ingredient of honey.
pollen
POLLEN
  • The male reproductive structure is called the stamen. It is composed of the filament and the anther. Pollen develops within the anther.
  • Pollen are dust-like grains which are unique to each type of flowering plant species.
  • Pollen consists of proteins, starch, sugars, fats, minerals, vitamins and free amino acids.
  • Bees collect pollen to feed their larvae.

POLLEN
  • When the bee goes to get nectar they trigger the male structures hence getting pollen on themselves.
  • Bees tend to confine their attention to a single flower species when foraging.
  • But they will move from plant to plant within that species hence favoring cross-pollination.
  • Some bees forage for nectar and other bees forage for pollen.
  • Some flowering plants will only offer offer pollen, others nectar. And some plants will offer both.
flowers that attract bees
Flowers that Attract Bees
  • Flowers have evolved to meet the needs of its pollinator.
  • Color also helps to attract pollinators.
  • Bee pollinated flowers tend to be brightly colored in the shades of blues and yellows.
plant list considerations
Plant List Considerations
  • How do you want to attract bees?
    • A meadow, prairie, crops
    • A vegetable garden, perennial bed
  • Some plants can benefit from bee pollinators but do not require bee visitation.
  • Then there are plants that require a specific insect.
  • Remember to choose plants that will bloom at different times throughout the season so you that bees will continue to visit.
  • Do your research – make sure you do not have invasive species!
  • Watch out for plants that are aggressive and can be difficult to control.
