Pollination and

Fertilization 101

What is Pollination?

• The transfer of pollen from a male part of

a plant to a female part of a plant

• Later enabling fertilization and the

production of seeds.

• This usually happens by an animal, insect

or wind.

What is Fertilization?• Merging of the male and

female genes to create seeds,

Stigma

Not all plants produce flowers with both the male and female parts. Those are noted as imperfect. Plants that produce separate male and female flowers on the same plant are called monoecious (men-ee-cious) (Latin meaning “one house”). Examples of this type of arrangement are cucumbers., pumpkins, corn, and European white birch.

Other species may have separate male and female plants with flower of only one sex on any plant. This is called dioecious (die-ee-cious) (again, Latin meaning “two houses). One example of this is holly. Only the female plant will produce berries and a male plant is close by to supply the pollen. Other examples of this type of arrangement is asparagus, spinach, and Japanese yew.

Attracting Pollinators

in the Garden

As a general rule….

• Plants that require pollinators usually have

large and/or bright/showy petals and

flowers

• Wind-pollinated plants tend to have

inconspicuous flowers

Tips for creating a pollinator habitat

• Plant your garden so something is always

flowering from early spring into late fall.

• Crocuses, tulips, etc. can start their food

supply in the spring

Tips for creating a pollinator habitat

• Also, some of our native bee pollinators need

a place to call home.

• In the fall, limit fall cleanup to establish

a habit where they can overwinter by

leaving some leaves on the ground and

not cutting your herbaceous perennials

back.

• Leave a small bare area; they can nest in

the ground.
