I recently got the chance to assess a university campus for bee-friendly landscape plants. Large trees and sprawling lawns made up the majority of the campus, creating a plush and welcoming blanket of greenery that encircled tall buildings and trees like draped velvet. I’m delighted to report that it provided a quiet retreat for students and many families using or passing through the campus with young children.
The campus had so many trees that they formed an almost closed canopy, giving the impression that the trees had given permission for structures to be placed amid them for our benefit.
On the university grounds, a variety of trees including oaks, American elms, ash, mimosas, catalpas, mulberries, willows, golden chain trees, lindens, flowering crab apples, hawthorns, cedar, fir, pine, horse chestnuts, honey locusts, and eastern redbuds flourished in harmony and profusion. Many of the huge shrubs and trees were pollinator-friendly.
Willows were the first bee-friendly trees to blossom in the spring, and they were soon followed by hawthorn, horse chestnut, red buds (both eastern and western), and flowering crab apples.
Up to the end of July, golden chain tree, honey locust, linden, catalpa, mimosa, and linden all produced continuous tree bloom.
As long as there are other pollinator-friendly plants blooming before and after them, each tree holds a significant amount of floral resources during bloom time and is beneficial to pollinators; bees require sustained floral resources during the growing season.
Conifers, ash, elm, and other wind-pollinated trees are generally unwelcoming to bees.
On campus, hydrangeas were widely planted, so it was fascinating to see which ones were good for pollinators and which weren’t. Although we don’t typically think of plants as being friendly to bees, some are actually quite alluring to bees while others are not.
There was a fairly lengthy planting of lacecap hydrangeas on the east side of a sizable structure. The more popular mop-head hydrangea macrophylla hortensis is unsuitable for bees since its flowers are all sterile and, while attractive to humans, provide neither pollen nor nectar for bees.
Although hydrangeas’ fruitful blossoms are little, unimportant, and not particularly eye-catching, bees are very drawn to them. A large core cluster of fertile flowers is surrounded by stunning sterile flowers on lacecap hydrangeas.
They combine grace and delicacy with flowers that are friendly to pollinators, giving you the best of both worlds. These beautiful flowers are available in a variety of hues, including white, blue, and purple.
Hydrangea aspera, sometimes known as rough-leaf hydrangea, is a too rarely planted lacecap variety. Zone 9 locations with maritime influences, enough water, and annual composting are best suited for its use. This lovely big shrub, which grows to a height of 8 feet and flowers in the late summer, needs filtered shade.
A ring of light purple sterile blooms surrounds the bright purple, extremely fragrant fertile flowers. Both we and the bees adore its blossoms.
The appeal of the various hydrangea paniculata varieties to bees varies. The elongated, white flower heads typically contain a mixture of viable and sterile blooms.
Some varieties have non-scented, primarily sterile flowers whereas others have highly fragrant, bee-friendly blossoms. All are garish.
It is better to visit a nursery and distinguish between plants with a lot of bees visiting them and others that are not aromatic. The plants can range in size from three feet to roughly six or eight feet. Numerous cultivars exist.
Native to the eastern United States, hydrangea arborescens is frequently planted along the coast or in regions that receive a lot of coastal impact. ‘Annabelle’ is a popular cultivar.
It features very enormous umbels of white flowers that resemble mopheads, but each blossom is somewhat smaller than the mophead varieties, giving the flowering plant a softer and more elegant appearance.
The leaves are a brighter shade of green, much smaller, and less waxy. Large flower heads and weak stems can cause flowers to occasionally topple down.
While cultivars like “Haas Halo” have lacecap blooms made up of both fertile and sterile flowers and are exceedingly spectacular and bee-friendly, this cultivar only has sterile flowers. H. arborescens has exclusively viable blooms in its wild form. The scent of hydrangeas can help determine whether they are bee-friendly.
Do hydrangeas entice wasps or bees?
The nectar and pollen-rich flowers of hydrangeas draw a variety of bee, fly, and wasp species as well as other flying pollinators. They don’t draw houseflies, hornets, yellowjackets, or the majority of predatory wasps because these insects are generally carnivores that eat carrion or trash and rarely consume nectar or pollen.
One of the main reasons that flowering plants exist and why most flowers are as beautiful as they are is because they attract pollinators. The color, form, and shape of a flower are created by nature to draw the type of animal she wants to help with fertilization. If you don’t want the pollinators, you must get rid of the plants, or at the very least, the flowers, or move them to an area where they won’t bother you.
Which varieties of hydrangea don’t draw bees?
You might think that hydrangeas are a bee attraction given their huge blossoms, but that isn’t necessarily the case. While certain varieties of hydrangeas draw bees, others do not. Flowers on mophead hydrangeas are sterile and lack nectar that would draw pollinators. Lacecap hydrangeas do, however, produce fruitful blossoms that draw bees. Pollinators like bees are also drawn to Climbing Hydrangeas, Oakleaf Hydrangeas, and Smooth Hydrangeas.
Mophead hydrangeas are the best choice if you want to keep bees away. On the other hand, if you want to make a space that attracts pollinators, consider growing Lacecap, Climbing, Oakleaf, or Smooth hydrangeas. The Lacecap and Oakleaf Hydrangeas appear to draw the greatest number of bees and other pollinators among these types.
You might ask why hydrangeas don’t draw in more pollinators given their opulent blossoms. Don’t pollinators want big, vibrant flowers, like bees do? It turns out that the nectar and pollen that the pollinators are truly pursuing are not present in every Hydrangea bloom. Most of the spectacular flower clusters that Hydrangeas are valued for are sterile. The cluster’s only viable flowers, which have nectar and pollen, are located inside.
The “petals on Hydrangeas are technically sepals, not blooms,” as the saying goes. Normally, these sepals would be green in plants. However, the outer part of hydrangeas mimics the shape that we usually refer to as a flower.
In the natural, hydrangeas produce more little, fruitful blossoms rather than large, spectacular flowers. The proportion of fertile to sterile flowers has changed as Hydrangeas have been bred by growers to produce larger blooms.
Because they don’t create a lot of pollen, hydrangeas are a suitable choice for allergy sufferers. Since there is no need to worry about pollen allergies, Hydrangeas are excellent for cutting and bringing indoors.
Do hydrangeas entice bees and butterflies?
When it comes to pollinator plants, hydrangeas are not often the first thing that come to mind. However, lacecap types like Little Quick Fire, which conspicuously exhibit their fertile florets that are rich in nectar and pollen, do a great job of generating buzz. Little Quick Fire is also a panicle hydrangea, which requires little maintenance and thrives in both hot and cold areas. Even though mophead kinds—those that produce the large, full, fluffy flower heads—are typically regarded as more showy, choosing lacecap variants guarantees that you’re also improving the aesthetics of your landscape.
Are bees attracted to panicle hydrangeas?
Meet Hydrangea paniculata, often known as a panicle hydrangea, and its various forms if you’re searching for a lovely, low-maintenance shrub with interest throughout all four seasons. One of these incredible shrubs belongs in every sunny environment, and here are four reasons why we believe you’ll agree.
A Reliable, Four-Season Show
Panicle hydrangeas never fail to fill your landscape with an abundance of color. They establish their blooms on new growth in the spring, protecting this year’s crop of buds from the harsh winters. Starting in the middle of July, panicle hydrangeas produce abundant clusters of white or creamy-white blooms after a spring covered in beautiful, bright green foliage. As late summer transitions into October, many other summer bloomers are starting to lose their vibrant colors. Depending on the variety, the blossoms gradually turn pink or lime-green, then colors of strawberry or burgundy. When the first frost hits, they become an appealing tawny-brown and stay on the plant, adding lovely texture to the winter landscape. Furthermore, unlike the well-known pink or blue mophead hydrangeas, none of these color changes are caused by a unique soil chemistry; rather, they take place as the evenings get cooler in the late summer and early fall.
A Perfect Fit for Any Sunny Space
There is a panicle hydrangea for every requirement in your landscape, whether it be a gorgeous anchor for a perennial bed, a magnificent blooming hedge along a border, a natural living screen, or a tiny splash of color in a smaller corner. Some cultivars grow large—five to eight feet tall and wide—and can fill a large area with several lovely blooms. However, some, like “Little Lime” or “Bobo,” are significantly smaller and can fit almost anyplace.
Even panicle hydrangeas in the shape of trees can be found, with their stunning blooms and leaves perched high above a single trunk. Even the smallest places may accommodate the lovely hydrangea blossoms thanks to tree hydrangeas. There is a panicle hydrangea to fit any landscape design thanks to the variety of form and function.
There are several designs for the clustered panicle blossoms as well. Some cultivars produce clusters that are more compactly packed and rounder, like the traditional mophead hydrangea that is common in formal gardens. Others, like Quick Fire and the tiny Little Quick Fire, have more open, airy blossoms that blend in well with the local vegetation in a setting that is influenced by nature. Additionally, some, such as Pinky Winky, develop large, highly conical clusters that resemble enormous aster flowers.
An Easy-Going Personality
Hydrangeas in a panicle are not picky. They won’t require much more care from us if they are placed in a location with four to five hours of sunlight every day, well-drained soil, and a little mulch to retain moisture in the summer. Pruning is also simple. A trim in late winter or very early spring won’t have any impact on the flowers of the next year as long as you avoid doing so when the buds are emerging in the spring and summer. Additionally, panicle hydrangeas are resilient enough to survive many of our harsh winters.
A Benefit to the Garden Community
Most harmful insects, including the vile Japanese beetle, seem to disregard panicle hydrangeas. However, panicle hydrangeas are even better because they draw beneficial insects that prey on some of the pests that may be harming your other garden plants. Soldier beetles and their larvae love the pollen and nectar from panicle hydrangeas; these voracious predators eat cucumber beetles, aphids, spider mites, and other pests that harm plants. The steel-blue cricket hunter parasitoid wasp, which feeds on the nectar of hydrangeas before employing insects like crickets and cutworms as incubators for its eggs, is attracted to panicle hydrangeas. A variety of bees, butterflies, and other significant pollinators are drawn to your landscape by the lovely white and pink blossoms.

Which hydrangeas provide food for bees?
The following hydrangeas all provide food for bees, but I’ve highlighted the hydrangeas that do so the most frequently (and, yes, other pollinators).
If you’ve ever seen a climbing hydrangea (Hydrangea anomala petiolaris) in its full beauty, you know how stunning it is. But beware—this one climbs and has aerial roots that cling to cement-like surfaces. A terrible choice for your home, but excellent for a dead tree or an old shed.
Despite the warning, this is a stunning plant with white blooms and dark green leaves. Although it can be pruned, it reaches 30 to 40 inches high or tall. The crowns of lacy white flowers are 8 to 10 broad. The flowers bloom from June through July and provide pollinators with both nectar and pollen. You get the impression that the garden has been there for a very long time when you see a mature Climbing Hydrangea. Zones 4-8.
Hydrangea Lacecap (Hydrangea mycrophylla)
Fertile flowers with flat crowns are surrounded by spectacular sterile blossoms. A lovely and sophisticated option for the garden. As the bloom ages, the color of the flowers can vary from blue to white to pink. The color of the flowers is influenced by the pH of the soil: blue in extremely acidic soils (pH < 5.5) and pink to purple pink in alkaline soils (pH above 7.0). To make the blossoms bluer or pinker, apply lime or aluminum sulfate, respectively. Grow either in full sun or some shade. Look for more hardy types if you live somewhere with a chilly climate. Zones 6-9.
Hydrangea with oak leaves (Hydrangea quercifolia) a wonderful supply of nectar and pollen. I adore oak-leaved hydrangeas because of their imposingly sized leaves. The borders do have an oak leaf appearance. Even when not in bloom, this hydrangea will stand out among other bushes because to its leaves. The white, rectangular flowers are 10–12 inches long, and the bushes can grow to a height of 5–10 feet. In the fall, the leaves become a stunning deep red. Both “cultivated areas” and more natural woodland settings should give this plant some thought. Grow in full sun or partial light, well-drained, acidic soils. Zones 5-9.
Hydrangea paniculata “Grandiflora” (PeeGee Hydrangea) The plant’s ability to feed bees has received conflicting reviews. I would probably select a different hydrangea if you are serious about providing a food source for bees and other pollinators. PeeGee has a lot of flowers that are sterile. Mid-summer brings forth white blossoms that mature into dusty roses. can grow in the majority of soil types. reaches a height and width of around 20 feet. zone 3 to zone 8.
* Hydrangea rough-leaf (Hydrangeaaspera) In contrast to other hydrangeas, Hydrangea aspera has almost all viable blossoms. They are aromatic and the bees adore them. Rich, evenly moist, well-drained soils in partial shade are best for growing plants. Only when cultivated on consistently moist soils will it tolerate full sun. This shrub’s blossom color is typically influenced by the pH of the soil. How to alter the color is described in the Lacecap explanation. Zones 6-9.
If you have the space, I highly recommend the “Tardiva” hydrangea (Hydrangea paniculata).
The flowers on Tardiva are a mixture of fruitful and infertile blossoms. The bees, however, seem to adore mine. In August, white blooms bloom, eventually turning dusty pink. For a shrub, this hydrangea can grow to be about 20 feet tall. In the shrub border, it sparkles. Or do you have a privacy barrier that is largely made up of trees? A tall shrub, like “Tardiva,” will complement trees better than a shrub of a typical size and look more in proportion. “Tardiva” may grow in any type of soil, excluding moist ones. zone 3 to zone 8.
Last but not least is the Wild or Smooth Hydrangea (Hydrangea arborescens). This is a native hydrangea with white flowers that attract pollinators and feed bees. from early to late summer, blooms. 3 to 5 feet in height. Great in groups or in masses. Dole out wet, organically rich, and well-drained soil. It can function in either full sun or shade. 3 to 9 zones.
