20 Fall Flower Bulbs to Plant for Spring Pollinators

When it comes to helping pollinators in spring, not all flowering bulbs provide the nectar bees and other insects need. Find out which bulbs can fuel our hungry pollinators while providing beautiful blooms at winter’s end.

Also see these ideas for growing a diverse selection of plants to support bees, butterflies, and more.

Using Flowering Bulbs to Support Spring Pollinators

You know those wonderful early spring days when winter has finally surrendered—at least for the moment—and the sun is shining and the bees come out seeking nectar?

With days or weeks to go before plants like dandelions and early flowering trees and shrubs start showing off their blooms, food sources are scarce.

And this is where the right flowering bulbs can save the day.

Plant them in fall and enjoy them in spring.

You can jump right to the list of recommended bulbs here or keep reading to understand why some flowers are never touched by pollinators and why our bulb selections matter.

Gardening for Pollinators

Gardening for pollinators is a simple arrangement.

We provide a diverse variety of food and habitat through suitable plant selections, give up the pesticides and all that harmful riff raff, and let the pollinators do their thing.

They eat, drink, and be merry consuming the nectar, pollen, or fruit, and, quite incidentally but so importantly, assist with flower reproduction. Keep reading if you’re not sure why this is a big deal (beyond pretty flowers).

These are unintentional but essential mutually-beneficial relationships that have co-evolved over millions of years.

While it may be a straight exchange with some plants and pollinators—you give me nectar, I distribute your pollen—our spring bulbs, which reproduce asexually, are more like cheerleaders on the sidelines providing fuel to sustain things until the main growing season gets underway.

How Pollination Works

So how does pollination happen? This is completely over-simplified and generalized but here is the gist of it.

As the animal forages—this could be a bee, bird, moth, wasp, bat, beetle, fly, or small mammal— male plant pollen from the flower stamen sticks to its body. The animal continues foraging and that pollen gets on the female parts (stigma) of either the same flower or a flower on another plant of the same species. The plant is fertilized and can now produce fruit and seeds.

Again, it’s not a direct exchange with early flowering bulbs which reproduce on their own and don’t need help with pollination, but their nectar is still valuable to those hungry critters.

With approximately 80 percent of the world’s flowers dependant on animal pollination and approximately 80 percent of food crop pollination assisted by bees—the rest by other insects, wind, and so on, it’s not a leap to say this is indeed essential for life on earth.

Why Not All Bulbs Are Beneficial

When I started researching this topic to learn which spring-flowering bulbs support pollinators, one thing stood out.

It’s not enough to choose the right plant species.

With all the hybrids and cultivars out there, you need to check that the specific species and variety is actually pollinator-approved.

Avoid Fancy Hybrids

For example, some flowering plants are bred to have frilly, double, or triple blooms or overlapping petals that look interesting but make it impossible for the insect to access the nectar or pollen.

This is not only true for flowering bulbs but all flowering plants produced for gardens.

In our zeal for fabulous new shapes and colors we have sometimes landed in beautiful but useless territory.

Once you become pollinator-centric, it’s the usefulness of plants that makes them beautiful.

Some hybridized flowers may come in colors or have odors so far from the original species that their pollinators are not attracted to them.

Others have little or no nectar and may also be sterile.

One example is tulips. What we call straight species tulips (Tulipa spp.) or unhybridized tulips are pollinator-friendly. But many of the fancy-schmancy hybridized tulips are not.

To know you’re getting the right bulbs, ask or check.

1. Can my local pollinators use this plant for nectar or pollen?
2. Is this a straight species or a hybrid that still provides easy-to-access nectar?

I also highly recommend learning the botanical names of your garden plants where you can.

Botanical taxonomy—the proper way to list the entire plant name—tells you things like species, cultivar, and hybrid names, making plant selection easier. Once you know the basic formula for how the written names are formatted, there’s a lot more information at a glance.

The Best Bulbs are Beautiful and Useful

With so many good options available and hungry bees and other insects depending on it, it seems a shame to plant flowers with nothing but good looks to contribute.

Use the list I’ve provided below, do your homework to confirm the choices are suited to your region and know you are growing something that will be both beautiful and useful.

Pollinator-Friendly Spring Flowering Bulbs and Other Geophytes

The plants suggested here are geophytes: perennial bulbs, corms, rhizomes, and tubers that store their food in underground stems or other plant organs. We use the broad term ‘bulb’ for all of them.

Bloom times vary from early spring onward.

If you are wanting native plants, check what is considered native in your area. Many of the bulbs listed below are non-native but still readily used by pollinators.

Also, check with your bulb seller to confirm your selections are pollinator-friendly and proven forage sources and will not be invasive or too aggressive in your garden.

If you want to save or print this list, see the link below.
