Pick hydrangea cultivars with more fertile compared to infertile blossoms to draw butterflies and other pollinators. Butterflies and other pollinators are definitely drawn to my Quickfire Hydrangeas. They were initially planted roughly 13 years ago, and they have since gotten pretty big. Photo taken on Quickfire on 8/9/20 of a Giant Swallowtail with a Red Spotted Purple.
Do hydrangeas attract butterflies and bees?
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.
What kinds of bugs are drawn to hydrangeas?
Typically, bugs do not cause much harm to hydrangeas. Making ensuring your hydrangeas are as healthy as possible will help you avoid damage. Give them the right amount of water to avoid stress, and that should be your top priority. This will increase Hydrangeas’ ability to survive mild pest damage without having an adverse effect on growth or attractiveness.
Encourage natural predators like ladybugs to live in your yard to naturally keep damaging insects like aphids and mites away from your hydrangeas. Ladybugs are helpful insects because they don’t harm your plants but eat other garden pests instead of bothering your plants.
If you want to attract ladybugs, plant flowers like cosmos, calendula, and marigolds. You can also make a ladybug shelter out of a tiny box packed with bamboo canes to provide the insects a spot to hide out close by. This natural predator may be more successful than an insecticide at keeping your Hydrangeas free of dangerous pests because one ladybug may consume up to 5,000 aphids.
However, even if you make a setting intended to lessen dangerous bugs, you can still experience certain problems because of circumstances outside your control. You can take action to get rid of the offenders if you discover that pests are picking on your hydrangeas.
Japanese beetles, leaf tiers, rose chafers, spider mites, aphids, and scale are the pests that attack hydrangeas the most frequently.
Japanese insects
These insects have copper wing covers and a head that is metallic green. They are roughly 1/3 to 1/2 inch long. Because they feed on foliage, these beetles primarily cause cosmetic damage, but the result can make hydrangeas appear less appealing. Neem oil or a pesticide can be used to treat the problem. You can also manually remove the plant pests and drop them into a basin of soap.
Bugs that feed on roses
These bugs are tan or pale green and smaller than Japanese beetles. When flying, rose chafers resemble wasps. They consume the leaves’ veins, turning them into skeleton-like structures. Use neem oil or insecticide to get rid of rose chafers, or you can hand-pick the insects off of the bushes and drop them into a pail of soapy water.
Leaf stacks
Small green caterpillars called leaf tiers “knot leaves together to build a pouch to protect themselves from predators.” The hydrangeas’ flower buds are harmed by leaf tiers, which might lead to fewer blooms. The only practical way to get rid of these caterpillars is by hand removal because insecticides are ineffective on them because they are camouflaged inside the leaves. Before disposing of the caterpillar or fused leaves in the trash or compost, trim off any damaged leaves. Do this as quickly as you can to protect the flower buds from further harm.
Spider mitesSpider mites are so tiny that you probably won’t ever see them, yet their impacts will be felt. If the infestation worsens, you may see a pattern of dots on the leaves of your hydrangeas, and eventually, the leaves will become yellow or bronze.
Due to their preference for warm, dry surroundings, spider mites can be avoided by keeping your hydrangeas well-watered. Although Hydrangea leaves shouldn’t ordinarily be damp, if you see spider mites, consider misting Hydrangeas with water. This occasionally causes the mites to fall off the plant. To rescue your hydrangeas if this doesn’t work, try a pesticide.
AphidsAphids are a little, green insect that seem to be drawn to all plants. Fortunately, they are simple to manage. They frequently drink the sap off the stems and leaves of hydrangeas, which can cause fungal problems. Spray your Hydrangeas with a water hose when you see aphids to get rid of them. Apply a pesticide if the aphids come back.
ScaleThese insects resemble little shells more than actual bugs. Pruning infected sections of your hydrangeas will get rid of the scale. If there are only a few insects, you can manually remove them or treat each one with neem oil with a cotton swab dipped in alcohol. You may need to use an insecticide if the infestation is advanced.
One Word of Caution
When using insecticides to control pests, keep in mind that many of them kill all insects, whether they are bothersome or not. This means that by using a pesticide, you run the risk of eliminating pest-controlling beneficial insects like ladybugs. Before applying chemical insecticides to hydrangeas, try natural alternatives.
Which flower is the most butterfly-attractive?
One of the best flowers for luring butterflies is the coneflower. It brightens up the scenery in the late summer. In a bed of low-growing perennials where stunning flowers will dominate the rest, plant echinacea.
The plants can withstand both severe Minnesota winters and mild Florida winters since they are consistently winter-hardy across the US. Once established, echinacea plants can withstand drought, which makes them a good choice for today’s water-conserving plantings. With their ease of adaptation to the wet-dry soil cycles typical of these plantings, they are a fantastic choice for rain gardens.
What plants venomous to butterflies?
The cabbage butterfly, also known by its Latin name Pieris rapae, is a little, white butterfly with black spots, as many gardeners are all too familiar with. The female, sometimes known as a “cabbage moth,” lays her eggs on plants of the Brassica (“Brassica”) family. These include kale, collards, pak choi, Brussels sprouts, cabbage, radish, and broccoli. The holes that seem to grow overnight are really caused by the larvae, greenish caterpillars known as “cabbage worms,” which hatch and reside on the undersides of the leaves and consume the plant leaves for food. If left unchecked, the caterpillars may negatively affect the growing plant’s quality. Typically, the eggs have been laid and damage has already been done by the time you start to notice the butterflies buzzing over your brassicas.
There are many suggested treatments to safeguard brassicas. They include:
- netting
- Brassicas and plants that repel butterflies are called companion plants. These can be high blossoming flowers or aromatic herbs like lemon balm, sage, oregano, borage, hyssop, dill, and rosemary (tall marigold, calendula)
- companion planting plants that are spaced apart and draw moths. For this, nasturtiums are excellent.
- spraying the plant with repellent mixtures. DIY solutions typically involve some dish soap and, if desired, neem oil (or a substitute), garlic, and cayenne. There are several recipes available online.
- Cleaning by hand involves manually flipping each leaf and eradicating cabbage worms. Once the worms enter a growing head of cabbage or brussels sprouts, it may be difficult to remove them.
It appears that the butterfly is territorial. Therefore, the actual insects will keep away from your brassicas if you place a “look-alike” decoy among them. On the internet, a variety of decoys are recommended. Everything, including white Xs with black spots on them and exact duplicates. They have been created using a variety of materials, including paper, fabric, white milk jug plastic, and full-color 3D printed plastic. The decoys have also been staked in the ground or fastened to objects so people can move them around. Each variant appears to be effective.
It appears that success requires the following two qualities:
- the female’s black markings (two spots/upper wing as opposed to one spot/upper wing on the male), and
- Increasing the size of the decoy slightly from the original. The adult’s wingspan is 1.5 to 2 inches, therefore making the decoy 2 inches is a decent size.
Here is a decoy that is straightforward to build and install, and it appears to operate effectively. We like it because it’s simple to create and because the tape gives the decoy both weather protection and a surface that moves easily in a breeze. If it works for you, let us know!
Do hydrangeas attract insects?
I’m aware that some lace caps feed the bees, but not all specimens do, as some have flatter heads than the “mop heads” kind.
However, on the Lacecap Hydrangea macrophylla Blue Wave in this image, I have observed several bees foraging. I intend to add more cultivars to this page in the future.
Which hydrangea varieties should you avoid?
Some hydrangeas are better left out of the garden if you are concerned that your planting decisions may benefit bees and other pollinators.
Since the flowers are infertile and provide no food to bees, French hydrangeas (Hydrangea macrophyllahortensis) often do not help pollinating insects.
These are the types with ball-shaped blossom heads, a compact circular “mop-head,” and no discernible flower anthers.
According to my personal experience, the unskilled foragers at most land, take a rapid flight away, or rest without eating.
Though even some of the kinds with “looser flower heads” are not particularly helpful to pollinators, it is advisable to concentrate on those that are popular with bees.
Do hydrangeas draw in animals?
Its leaves don’t seem pleasant to insects, so there isn’t much value there, and most importantly, the blooms seem so ugly to insects. It isn’t dense enough or prickly to provide birds with a place to shelter. It’s really easy to understand why. The enormous flower globes that you notice on so many hydrangeas are completely sterile.
Which creatures are drawn to hydrangeas?
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.
Hummingbirds enjoy hydrangeas, right?
We like seeing hummingbirds both at home in Texas and while on the road around the nation.
We also like to garden for hummingbirds and plan our yard so that different species of hummingbirds can find food and a place to live.
Hummingbird Shelter
Although food and water may seem like obvious needs, hummingbirds also need shelter and protection.
In addition to offering protection, trees’ thick foliage serves as a source of insects and the protein they deliver. Large shrubs and trees offer a spot to rest in between meals at the feeder or flowers.
The Hummingbird Central garden, which offers food and essential shelter to hummingbirds, is a portion of which is shown below.
Hummingbird Food in Nature
The hummingbird feeds on flower nectar (red is their preferred color), tiny insects like aphids and spiders, and occasionally even pollen and sap.
Hummingbirds consume numerous little meals throughout the day, including up to twelve times their body weight in nectar and tiny invertebrates.
Hummingbirds help pollinate a variety of plant types in exchange for nectar and tiny insects from the plants. Even when not feeding, hummingbirds aggressively and tenaciously guard a feeder.
Water Features
The majority of wild birds love having a bird bath to use for drinking water or bathing. A “cold swim in the pool” is something hummingbirds like to do on warm mornings or scorching afternoons.
They appreciate shallow, moving water, such as a small waterfall or gently flowing water. The market offers a wide variety of water features in terms of brands, models, and sizes.
Some outdoor enthusiasts transform a basic birdbath into one with motion and song by using a little solar-powered pump. Zero wires! Move it around your yard if it’s flexible.
Hummingbirds frequently like flowers that are red in color and tubular in shape, so we include many plants with these characteristics.
In order to provide hummingbirds with the nectar and food they require to survive, we grow flowers, bushes, and trees. Our landscape contains a variety of natural habitats. It is located in a rural area and has hundreds of acres of forest backing it, as well as surrounding fields and pastures.
During the fall migration through Texas toward the south, we frequently had more than 40 Ruby-Throated hummingbirds on our feeders at once. On occasion, we are also fortunate to have a large number of colorful Baltimore Orioles visiting our feeders!
Butterfly Bush
We now have a variety of butterfly bushes planted, and they are all favorites of hummingbirds and butterflies alike.
Buddleia davidii, or butterfly bush, has long, 4-5 inch flower spikes that resemble and smell like miniature lilacs and typically blooms from mid-July until frost.
Butterflies are drawn to buddleia blossoms by their honey-scented fragrance, and once they arrive, they discover the flowers to be incredibly nectar-rich.
We make use of dwarf and full-size types in white, purple, and reddish hues. In a mild climate, full-size species may reach heights and diameters of up to 6 feet in just one season.
Make sure the soil where they are planted has good drainage, and avoid the need to overwater them.
The fact that butterfly bushes never shed their dead blossoms is their main flaw. Periodically, we remove the dead blooms, and in places where there is a lack of room, we also prune the bushes. In milder climates, they will typically spout and develop from their base the next spring. They are frequently frost proof until approximately 25 degrees; below that, they will freeze to the ground.
Lantana
We have over 45 plants flourishing right now, with several varieties of lantana, including yellow, white, red, and orange, demonstrating how much we adore this plant.
In a large portion of the South, lantanas are perennial plants that demand well-drained soil and will bloom in either full sun or light shade. Native to the semi-desert, they thrive best when neither overfed nor overwatered.
In many parts of the South, they can last the winter, and even in places where the ground freezes almost to the surface, they quickly grow in the early spring.
Other Favorites of Hummingbirds
Along with Lantana and Butterfly Bush, our landscape also frequently has Zinnias, Pentas, Milkweed, Salvia, Batface Cuphea, Hot Lips, Fire Bush, Nasturtiums, and other annual and perennial plants that are hummingbird-friendly.
We also plant gladiolas, geraniums, hydrangeas, impatiens, verbena, and roses, which, though they might not be hummingbird favorites, offer additional color to the landscape. Hummingbirds adore color, and they all give vibrant hues!
Numerous Azaleas, Pansies, Impatiens, Knockout Roses, Creeping Phlox, Daffodils, Hydrangeas, Portulaca, and Gladiolas are other landing and feeding locations that vary by season.
A Final Ingredient: The Hummingbird Feeder
The correct flowers must be planted in order to create an environment that will draw hummingbirds.
But you also need a hummingbird feeder, which is a crucial attractant! Hummingbirds begin to share feeders as the Texas migration peaks here in late August and early September, a behavior unheard of during the summer when protecting a feeder is the norm.
