How can we attract a variety of pollinators to our gardens? Plant diversely. Each type of pollinator has unique needs that certain plants provide. Kim Eierman, author of The Pollinator Victory Garden, shows us which traits to look for in our plant selections to encourage greater biodiversity.
Bees get a lot of well-earned attention, but there are many other pollinators you can learn about here.

If you aren’t seeing a wide variety of different pollinators in your landscape, it’s likely time to ramp up your plant diversity.
Flowering plants have developed a number of traits to attract specific pollinators.
Not all pollinators are attracted to, or can utilize, the same type of flowers.
Overall plant features such as flowering time, density of flowers, number of flowers, flower height, and spatial pattern of flowers can influence which pollinators will use a given plant.
A pollinator’s body size, strength and tongue length also determine which plants can be accessed by which pollinators.
Long-tongued bees and hummingbirds are adapted to plants with long, tubular flowers while shorter-tongued pollinators, like hover flies and European honey bees, require plants with more open flower structures.
Pollinator Syndromes
An individual flower’s color, shape, structure, size, fragrance, and availability of nectar and/or pollen also help determine what type of pollinator will visit.
The combined groups of traits that predict the type of pollinator that will be attracted are known as “pollinator syndromes.”
Flower Traits That Make Up Pollinator Syndromes
- Color
- Shape
- Fragrance/odor
- Presence or absence of nectar guides
- Nectar availability
- Pollen availability
Exceptions do occur, but these pollination syndromes generally hold true.
The more flower traits you include in your garden, the wider the array of pollinators you will attract.
Keep in mind that the more flower traits you include in your garden, the wider the array of pollinators you will attract.
Pollinator Syndromes (Flower Traits) by Pollinator Type
If you want your garden to attract wide-array of pollinators, I highly recommend getting the book. It is filled with native plant suggestions for continuous blooms from spring to fall to keep the pollinators coming. ~Melissa

Pollinator syndromes are key, but don’t forget about the other aspects of your garden that are so important to pollinators including:
- a continuous succession of bloom throughout the growing season
- pesticide-free habitat
- native plants that native pollinators have evolved with and may depend upon

Thank you, Kim!
Now it’s time to look over our gardens and determine which pollinator plants we need to add.
