Flowers are intended to draw people into the yard as well as, of course, beneficial insects and other creatures. It is possible for this attraction to take the form of a scent, color, shape, accessibility to nectar, pollen content, or a combination of all of these. At Petitti’s, we take great pleasure in honoring our vital pollinators and raising awareness of their vital functions. Given that we depend on bees for the success of all plant-based food sources, bees are among the most crucial pollinators. Continue reading to discover some fantastic annual plants that you can use to help them in your garden as well!
Basically, any kind of annual bloom! The better, the more blooms. Additionally, diversity is great. The breadth of plant species and flower hues available is astounding, and annuals are known for their floriferous nature and for putting on a show of non-stop color from spring through fall. The bottom line is that you can’t go wrong when planting annuals to benefit bees and other pollinators. In essence, your favorite annual will also be the bees’ favorite annual.
Definitely, marguerite-type daisies like Argyranthemum Pure White ButterflyTM are a favorite of bees. This species of daisy has exceptional heat tolerance and produces continuous blooms without the need for deadheading, which is advantageous to gardeners. Marigolds, Sunflowers, and Zinnias are other members of the daisy family that attract bees because they contain a central landing zone, or “eye, which is loaded with nectar.
The delicate hues of the Begonia’s doubled, pastel blooms and the heat-tolerant, trailing Bacopa MegaCopaTM “Bees are drawn to unbelievable series because they best associate with yellows, whites, blues, and violets. However, these two types outperform their ancestors to function admirably in both sun and shade, as well as heat and humidity, to continue flowering. Most Bacopa and Begonias prefer the safety of a shady place. They draw bees in with their shallow, pollen-rich centers.
Bees are also very well attracted to the appealing tubular centers of Calibrachoa, which are clearly marked with a bright yellow entrance. And since there are so many lovely possibilities for filling and spilling, self-cleaning Calibrachoa, it’s enticing to think about growing them all in bright hanging baskets and other containers.
Remember that bees are attracted to fragrant, fresh scents as well, such as the simple, warm-loving, free-flowering Dianthus JoltTM Pink. In fact, hummingbirds, butterflies, and bees are attracted to any type of Dianthus.
We would be negligent if we were to add the ever-supportive leaf accent plants that we employ as thrillers, fillers, and spillers, such as the incredibly adaptable Coleus Prince TutTM, regal Cyperus Prince Tut, and the striking but lovely Ipomoea (Sweet Potato Vine). Though the flowering Ipomoea “FloraMia Nero may be the best of both worlds!, their function is not to attract pollinators but rather to produce the texture and color that make flowering plants “POP in the garden.
Proven Winners Supertunias, the popular Wave Petunia series, the irresistible deep purple bi-color Sweetunias, the adorable heart markings of the Amore Petunia series, and other self-cleaning, perpetually blooming Petunias are just a few of the advancements made in self-cleaning, ever-blooming Petunias each year. Although petunias only averagely draw bees, they work effectively to draw all pollinators when combined with smaller clustered blooms like Verbena and Lantana.
The improbable SunPatiens are no different. These easy-care plants can be grown anywhere and combined with other annual species to create a haven for pollinators.
Which flowers entice bees the least?
Comparatively speaking, bees have a much wider color spectrum than humans do. Because scientists and researchers have examined bees’ responses to various sugar-water feeder colors, we are aware of this. The potential demise of bees can be avoided by researching their field of vision. We can grow more flowers that will attract them and feed them with nectar and pollen if we know which hues they prefer.
Bees are able to perceive the majority of hues, including ultraviolet (which humans cannot see), but not infrared or red. Although red is a difficult hue to locate even in plants, this understanding is particularly important for this post. God created plants in close proximity to bees because most plants require pollination by insects or animals in order to develop healthy seed.
How can our understanding of bee eyesight help gardeners? Red and infrared light appear black to bees. To entice bees into the center of the bloom, some flowers now use red as an alternation between other colors, nearly producing a landing strip light section. If a plant has a design to draw bees to the center, such as the red and yellow stripes on Blanketflower (a Gaillardia species), you will know it.
Plants with Red Flowers that Bees are Less Attracted to
We should be able to add flowers to the garden that are less alluring to bees just based on flower color as long as we avoid blooms having patterns of alternating colors, like red and yellow. But which red flowers are the finest bee-resistant ones?
Perennial Flowers that do not attract bees
- Oriental lilies come in a variety of species and cultivars, with colors ranging from dark crimson to vivid scarlet. Over time, they build substantial mounds in the garden.
- An older variety of yarrow called “Paprika” retains a vibrant red color while in bloom.
- Mint hummingbird (Agastache)
- Several red-flowing plants are specifically attracted to hummingbirds.
- Red-Headed Poker
- This heat-loving perennial blooms only briefly, but the bees are scared off by the red color and flower form.
- A native perennial with purely scarlet blossoms, the cardinal flower is perfect for muck or rain gardens.
- Irish Cross
- the majority of varieties are red and unattractive to bees, while there are some pink variety.
- Most chrysanthemums have two flowers and no pollen or nectar, so bees are not attracted to them.
- Even though roses are attractive, few bees will pollinate modern cultivars like the “Knockout,” “Easy Elegance Series,” or “Drift Series.”
While the red petals of many other species may be less alluring to bees, they frequently contain yellow cores that bees may accidentally step into.
Annual and Tropical Flowers that do not attract bees
- Bees are not drawn to petuniared variations, however I have observed bumblebees examining other colors.
- Bees hate Celosia because of its flower structure and its repulsive red hue.
- Hummingbirds love the scarlet blossom on the Cardinal Vine, while bees avoid it.
- Another plant with two flowers that bees find challenging to get is the marigold.
Are wasps attracted to petunias?
I appreciate you asking. The fact that wasps feed on other insects and hence control them makes them useful in the landscape. Even though certain wasps are regarded as annoyance pests, they are rarely dangerous or aggressive until provoked. Social wasps are often not violent until their nests are disturbed (yellowjackets may be an exception). Please refer to CSU Extension Fact Sheet 5.525, “Nuisance Wasps and Bees,” for more details on nuisance wasps.
The type of wasps present determines how to control them. If the wasps are sociable, destroying the nest might help reduce the number of wasps that visit your petunias, but there might be additional nests nearby. If the wasps are solitary, they can nest anywhere and are typically helpful, non-aggressive, and uncontrollable.
There aren’t many chemical control methods that will work unless the wasps are eating the petunias directly, which is doubtful. A systemic pesticide can be used to control a variety of plant-eating insects, however because plants absorb these chemicals, the insects must directly feed on the plants in order to come into touch with the insecticide. The wasps will be tough to manage with a contact insecticide due to their rapid mobility.
It’s possible that the wasps are drawn to your petunias because they provide a food supply (insects, sticky honeydew made by insects that feed on sap, like mealybugs or aphids), or possibly because they are getting their water from the flowers or leaves. Taking away attractants might make them less noticeable.
Make sure to use an insecticide that specifically mentions wasps on the label if using one. When spraying a pesticide, especially with flowering plants, extreme caution should be exercised because bees and other beneficial insects may be damaged. The use of several insecticides on flowering plants is strictly forbidden.
What draw people to petunias?
Petunias can be produced from potted plants or from seeds that are started early indoors and moved outside after a frost.
Indoor Seed Sowing
- Use a seed starting kit to indoor sow petunia seeds eight to ten weeks before the last frost.
- Seeds should be thinly sown and barely pressed into seed starter mix. Don’t bury under earth.
- At 70 to 75 degrees, keep the soil moist.
- Seedlings appear after 10 to 14 days.
- As soon as seedlings appear, give them lots of light on a sunny windowsill or grow them 3–4 inches beneath 16–hour-per-day fluorescent plant lights that are off for eight hours at night. As the plants get taller, turn up the lights. Because they will become too hot, incandescent bulbs will not function in this process. Do not leave lights on continuously for 24 hours; most plants need a time of darkness to flourish.
- when they have two sets of leaves, thin to one seedling per cell.
- Seedlings don’t require a lot of fertilizer; feed them when they are 3–4 weeks old with a starter solution (half the strength of an indoor plant food), as directed by the manufacturer.
- After the first frost, transplant hardened-off seedlings into the garden.
- Seedling plants must be “hardened off” before being planted in the garden. By relocating young plants to a protected area outside for a week, you can acclimate them to outside circumstances. At first, be sure to shield them from the wind and the light. If frost is expected at night, cover or bring pots inside; then, in the morning, reintroduce them to the outdoors. The plant’s cell structure is toughened during the hardening off process, which also lessens transplant shock and scorching.
In the Garden, Plant Potted Plants:
- Choose a place with good, rich, moist, well-drained organic soil and full sun.
- Turn the soil under to a depth of 8 inches to prepare the bed. To get rid of grass and stone clumps, level the area using a rake.
- The majority of plants do well in soils that have had organic matter added. Compost is a beautiful organic material that can be applied to your planting area whenever you like. It has the perfect pH level and nutrient balance. If compost is not available, topdress the soil with 1-2 inches of organic mulch after planting; this mulch will break down into compost over time. Following the growth season, a soil test will reveal what soil amendments are required.
- In the garden, plants should be spaced 6 to 12 inches apart.
- For each plant, create a hole that is sufficiently large to hold the root ball.
- Set the top of the root ball so that it is level with the dirt around it. Up to the top of the root ball, cover with soil.
- Your hand should firmly push the earth down, leaving a small depression to hold water around the plant.
- Water deeply until a puddle appears in the saucer you have made. As a result, there is strong root-to-soil contact and the plants become established.
- Use the plant tag to indicate its location.
How to Grow
- Keep weeds under control while the plants are growing. Weeds compete with plants for water, space, and nutrients, therefore keep them in check by frequently cultivating or by using a mulch to stop the germination of their seeds.
- Mulches also support stable soil temperatures and moisture retention. Shredded leaves used as an organic mulch for annual plants give the bed a more natural appearance and, as they decompose over time, enrich the soil. Mulches should never be placed on a plant’s stems to avoid potential decay.
- During the growing season, make sure plants are well-watered, especially during dry spells. The growing season requires roughly 1 inch of rain every week for plants. To determine whether you need to add water, use a rain gauge. The optimum irrigation method is a drip or trickling system that releases water at low pressure directly into the soil. To reduce disease issues, water early in the day if you want to use overhead sprinklers so the foliage has time to dry before dusk. Maintain a moist but not saturated soil.
- Some protection from strong winds and intense sunlight may be required until plants grow established. Additionally essential is good airflow.
- A mild fertilizer can be administered after new growth starts to show. To prevent burn damage, keep granular fertilizers away from the plant’s top and leaves. Use moderate amounts of a slow-release fertilizer because greater amounts could promote root rots.
- To promote flowering and stop the production of seeds, remove wasted flower spikes. Plants’ growth tips can be pinched to promote bushiness.
- Observe for illnesses and pests. For advice on pest management measures that are suitable for your area, contact your cooperative extension service.
- In order to prevent disease problems the next year, remove plants that have been killed by frost in the fall.
Growing Tips
- Cut back straggly petunia plants by half in the late summer to promote growth and the development of new flowers.
- Petunias make lovely edging plants and can be used in mixed plantings with other annuals that bloom in the summer. They look fantastic alone or in combination with other flowers in pots of different shapes and sizes.
- Hummingbirds and moths are drawn to the yard by petunias.
Common Disease Problems
Aster Yellows: Plants grow excessively, become stunted, and develop witch’s brooms. Their petals also turn green and become malformed. Leafhoppers propagate this virus-like ailment. Burpee advises removing diseased plants and managing leafhopper populations. Eliminate any weeds in the area that the illness can also live on.
Botrytis: This fungus turns flowers, leaves, stalks, and buds a greyish color. It thrives in chilly, rainy weather. Burpee advises removing the damaged plant sections, avoiding watering at night, and not watering directly on the plant. Make sure plants receive adequate airflow. For advice on fungicides, get in touch with local cooperative extension service.
One of the most frequent issues when beginning plants from seed is damping off. The seedling appears healthy when it first emerges, but then it mysteriously begins to droop and die. A fungus that causes damping off is active when there is a lot of moisture present when the soil, air, and temperature are above 68 degrees F. This typically means that the soil is either too moist or heavily fertilized with nitrogen. Burpee advises keeping seedlings moist but not overwatering them, avoiding overfertilizing them, thinnng out seedlings to prevent overcrowding, ensuring the plants have good air circulation, and if you are planting in containers, washing them thoroughly in soapy water and rinsing them in a 10% bleach solution after use.
Fasciation is the unnatural flattening of stems, which can give them the impression of being joined. Often, distortion starts to appear in the plant’s base. It usually enters the plant through a wound and is brought on by a virus or bacteria. Burpee advises being extremely cautious when handling plants. Any plants that exhibit disease symptoms should be removed and destroyed.
When the weather is humid, a fungus illness known as powdery mildew develops on the tops of the leaves. The surface of the leaves seems to be white or grayish, and they may curl. Burpee advises giving the plants adequate air circulation through optimum spacing and pruning in order to prevent powdery mildew. For advice on fungicides, get in touch with local cooperative extension service.
Common Pest and Cultural Problems
Aphids are disease-carrying sucking insects that feed on the undersides of leaves and can be green, red, black, or peach in color. On the foliage, they deposit a sticky substance that draws ants. Burpee advises attracting or introducing aphid-eating predators like lady beetles and wasps into your garden. You can also use an insecticidal soap or a powerful spray to wash them away.
Cyclamen mite: By suckling juice from leaves and stems, these mites harm plants. They proliferate quickly in hot, dry conditions. They are only seen with the aid of a magnifying glass. Plants may not blossom and will appear stunted and deformed. Flowers will have streaks, blotches, and distortions. The leaves may cup, curve, get smaller and thicker. Burpee’s Advice Infested plants should be thrown away. Don’t work with plants that are infected. In dry conditions, keep plants well-watered. For advice on insecticides for severe infestations, contact local cooperative extension service.
Leafhoppers: These insects damage leaves and retard growth. Moreover, they spread sickness. Burpee advises clearing up plant detritus. Use soaps with insecticides. For additional advice on insecticides, contact local cooperative extension service.
Spider mites: These minuscule insects, which resemble spiders, are approximately the size of a peppercorn. They can be yellow, brown, black, red, or black. They ingest plant liquids, sucking out chlorophyll and injecting poisons that leave the foliage with white spots. On the plant, webbing is frequently seen. They cause the leaf to stipple, dry, and become yellow. They proliferate swiftly and do best in dry environments. Burpee’s Advice Every other day, a strong spray can help control spider mites. Try using insecticidal soap or hot pepper wax. For advice on miticides, contact your local Cooperative Extension Service.
Thrips: Thrips are little, straw- or black-colored, needle-like insects. They attack flower petals, leaves, and stems while sucking plant liquids. The leaf surface of the plant will show stippling, discolored flecking, or silvering. Numerous illnesses can be transported from plant to plant by thrips. Burpee advises placing sheets of aluminum foil between plant rows to deter many thrips. After the first frost, remove all weeds from the bed and any debris. For information on pest control, contact your cooperative extension service.
FAQ
Why did my petunias produce a stripe or change color in the summer? Petunias can change color or develop a stripe when it becomes too warm since they are sensitive to high temperatures. New blooms will return to their original hue as the weather cools.
What petunia has self-cleaning qualities? Petunias of the Wave variety, including “Baby Duck,” are all self-cleaning and don’t need to be deadheaded.
Why are “Shock Wave” petunia seeds different from standard petunia seeds? For convenience of handling, “Shock Wave” petunia seeds are pelleted. The covering will degrade once seeds are pressed into the soil and can be misted off.
What draw something to the garden? Hummingbirds, butterflies, bees, and other helpful insects are drawn to petunias.
I need Wave petunias for a 12-inch hanging basket, how many should I buy? For a 12-inch hanging basket, three Wave-varieties plants and four other mounding-habit species are the perfect number.
