Gaillardia, also referred to as blanket flower, blooms all summer with daisy-like blossoms. Gaillardia grandiflora, a short-lived perennial blanket flower, frequently reseeds itself. There are various ways to prepare blanket flower for the winter. Mulching and cutting back blanket flower plants, according to some gardeners, are the best practices. Others choose to deadhead instead than prune and skip mulching. Let’s talk about blanket flower preparation for winter.
Are Gaillardia plants cold-hardy?
When it comes to putting blanket flowers to bed (see what I did there? ), you have two choices. Depending on your preference, you can either prune your plants to enjoy a neat garden or leave them alone for winter appeal.
As you enter the winter months, there are a few additional general things to keep in mind. Although the plants are usually resilient and easygoing, they are not unbeatable.
The majority of cultivars can survive in Zones 3 to 9, so you usually won’t need to worry about giving them any additional winter care, such as mulching the roots carefully or transferring the plants to a protected area.
Contrary to more delicate plants like calla lilies and dusty miller, your Gaillardia probably won’t need any of these additional precautions to survive the winter.
Gaillardia x grandiflora ‘Mesa Yellow’ is one cultivar that isn’t quite as cold tolerant as others of its relatives.
Can Gaillardia be grown in pots?
In the summer, gaillardia seeds can be sown directly in the garden or as potted plants.
Direct Sowing in the Garden
- After there is a risk of frost, direct sow in poor but well-drained soil.
- Take out the weeds and smooth and level the top 6 to 8 inches of soil after working in organic matter.
- Spread seeds thinly and evenly, then top with fine dirt that is 1/4 inch thick.
- Lightly compress and maintain evenly moist.
- Depending on the soil and weather, seedlings will sprout in 7–14 days.
- When big enough to handle, they are thin enough to stand about 15 inches apart.
How to Plant Potted Plants:
- Select a site with poor but well-drained soil that receives direct sunlight.
- Turn the dirt under to a depth of 6 to 12 inches, remove any debris, and lightly rake the soil as level as you can to prepare the bed.
- To lessen transplant shock, plant during gloomy weather or in the late afternoon.
- For each plant, create a hole that is sufficiently large to hold the root ball.
- To promote healthy root growth, unpot the plant and use your hands to gently release 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. With your hand, forcefully press the earth.
- Use the plant tag to indicate its location.
- To save water and prevent weeds, thoroughly moisten the soil and sprinkle a thin layer of mulch (no thicker than two inches) on top.
How to Grow
- Keep weeds under control while the plants are growing. In order to suppress weeds, either cultivate frequently or apply a mulch to stop their germination. Weeds compete with plants for water, space, and nutrients.
- Mulches also support stable soil temperatures and moisture retention. When used as a mulch for perennial plants, weathered bark or finely chopped leaves 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.
- Perennials need to be watered carefully to get them started. To encourage young roots to swell deeply, water thoroughly at least once each week. One inch or so below the soil’s surface, the soil should be wet. By placing your finger in the ground, you can verify this. Water in the early morning hours so that all of the leaves have time to dry. The majority of perennial plants need an inch of rain or weekly irrigation. Using a rain gauge, you can determine whether you need to add water. Once established, gaillardia can withstand drought.
- Some protection from strong winds and intense sunlight may be required until plants grow established. Additionally essential is good airflow.
- Plants need to be deadheaded to keep blooming.
- Every two or three years, divide the plants in the spring or fall.
- Be careful not to overfertilize because plants prefer poor soils.
Growing Tips
- Many gardeners wait until the new foliage emerges in the early spring before pruning perennial flower seed heads in the fall. Wildlife will have food during the winter thanks to this.
- Gaillardia is a great choice for a wildflower meadow, the cottage garden, and the centre of a border. When planted in large numbers, they are rather striking.
- The gaillardia blossom is lovely when cut.
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.
Bacterial Leaf Spot: The spaces in between the veins of the leaf get dark brown and collapse. The entire plant might perish. Flower heads may be impacted by the disease and become deformed. Burpee advises getting rid of diseased plants. Avoid watering from above. When plants are damp, stay away from them.
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.
Root Rots: Both mature roots and seedlings can develop root rots, which are caused by several pathogens. Pull up and remove diseased plants, advises Burpee. Don’t overwater plants and don’t pile mulch up against them.
Septoria Leaf Spot: This is particularly prevalent in densely planted gardens during rainy seasons. On the leaves, there are tan areas with small fungi fruiting structures that resemble dark brown to black dots. Burpee advises clearing away all plant debris that is contaminated. When plants are moist, avoid handling them or touching them. Avoid passing over water.
Common Pest and Cultural Problems
Aphids: These disease-transmitting sucking insects that feed on the undersides of leaves might be green, red, black, or peach in appearance. 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.
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.
Slugs: These pesky insects consume entire leaves or leave big holes in the vegetation. They feed at night, leaving a slime trail, and are especially problematic in wet weather. Burpee’s Advice Hand select, ideally at night. You can try using cornmeal or beer to lure the slugs into traps. Create a hole in the ground and fill it with a huge cup or bowl to serve as a beer trap. Make sure the object has steep sides so that the slugs can’t escape once they’ve finished. Beer should be poured into the bowl until it is about 3/4 full. The basin should be filled with drowned slugs by morning so that they may be emptied outside for the birds to consume. Put a spoonful or two of cornmeal in a jar and place it on its side close to the plants to create a cornmeal trap. Slugs are drawn to the smell, but since they are unable to digest it, it will kill them. Diatomaceous earth or even coffee grounds can be used to create a barrier around your plants. They are too big to crawl over these.
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.
When plants are agitated or brushed against, little white flying insects known as whiteflies frequently rise up in a cloud.
They are challenging to control without chemicals, according to Burpee. Try using insecticidal soap or hot pepper wax. For advice on which pesticides to use, contact your cooperative extension service.
Gaillardia FAQs
Can Gaillardia be grown in a container? Gaillardia is acceptable for containers, yes. A commercial potting mix should be used, and proper drainage should be guaranteed.
Why failed to blossom on my gaillardia? If you simply sowed this year, your gaillardia won’t blossom until the next year because it blooms the second year after seeding. Gaillardia is also sensitive to fertilized soil and needs at least six hours of sunlight each day. Make sure not to overfertilize if the plant is flourishing in direct sunlight.
Why ought I to cultivate gaillardia? If you have the ideal conditions (full sun and well-drained soil), gaillardia is very easy to grow, attracts pollinators, blooms for a long season, makes beautiful cut flowers, has a variety of bright, cheery colors, and requires very little maintenance.
Do blanket flowers grow year-round or only occasionally?
Gaillardia make me think of a devoted dog who gives little in return, labors tirelessly in the sweltering sun with little water, is resolutely joyful, but perishes far too soon. Genetics are entirely to blame. Most hybrids, referred to as Gaillardia grandiflora, are offspring of annual blanketflower (G. pulchella) and perennial blanketflower (G. pulchella) crossings (G. aristata). Their partially perennial nature and ability to tolerate cold come from their perennial progenitor. Their predisposition to be short lived as well as their extraordinarily long bloom period and heat tolerance derives from their annual parent. Expect two years, and you’ll be thrilled if they succeed in four.
Gaillardia is a native of the North American prairies, and its common name, blanketflower, alludes to the hues used in the blankets worn by the American southwest’s native peoples, ranging from yellow through orange, bronze, maroon, red, and burgundy. It might have also originated from the way these blooms previously covered the prairies.
The native species (G. aristata) produces solitary, daisy-like flowers that are about six centimeters in diameter. The flowers’ long, narrow, yellow-orange petals, known as ray flowers, are serrated at their tips, and they are surrounded by shorter, brownish-purple disc flowers in the center. By mid to late June, they are in bloom, and they last through August. They are found in the dry uplands and prairie grasslands of Canada. The plants range in height from 30 to 90 centimeters and are erect but somewhat spreading. The native species readily reproduces and has a three to four year lifespan. It is (unfortunately) rarely seen in gardens and is often only available at nurseries that specialize in native species.
In full sun and well-drained soils, blanketflowers can thrive with minimal maintenance. They struggle in dense clay. Since they don’t live very long, the soil should not be mulched around them so that they can self-seed. Prior to a strong frost, blooming stems should be pruned to promote fresh basal buds. In the spring, they take a while to start growing again, so be patient and don’t dig them up. To extend the bloom, deadhead. In the middle of the summer, divide clumps by making a vertical cut along the side. Where the roots were removed, new plants will grow.
Gaillardias grow beautifully in the “They can self-seed in a hot border, a rock garden, pots, as cut flowers, and during naturalization. They provide nectar for bees and butterflies.
For many years, G. grandiflora hybrids Burgundy and Goblin have been grown in prairie gardens.
‘
Burgundy (Zone 2) is a robust plant that grows to a height of 60 to 90 centimeters and has semi-compact, single, dark wine-red flowers that are 7 centimeters in diameter. Goblin (Zone 2) is a mound-like, compact, dwarf cultivar with grey-green foliage that barely grows 30 to 45 centimeters tall. Petal tips on the crimson petals of the single flowers are yellow. It grows from seed and blooms the first year, making it a good choice for the front of a perennial border or a rock garden.
Less extensive testing has been done on the prairies with the newer cultivars.”
Place them in more protected areas and treat them like annuals.
Bright mahogany-red flowers with yellow tips are eight centimeters in diameter and are produced by Arizona Sun (Zone 3), a 2005 All America Selections winner. It is a 25 centimeter tall, compact, dwarf shrub with green foliage that blooms from June to September.
A beautiful peach-apricot color with touches of yellow and nearly ruffled petal tips, Summer Kiss (Zone 3) is a seedling selection from Goblin. It is compact, erect, and low growing (45–60 centimeters), with medium green foliage. With five centimeter-diameter flowers, it blooms in the middle of the summer.
Fanfare (Zone 3) features tubular orange-red ray petals with vivid yellow tips that encircle a scarlet center that resembles velvet. It stands 45 to 60 centimeters tall and has a compact, mounded shape. With flowers on upright, robust stems, it is exceptionally floriferous and good for cutting.

Deadhead your Gaillardia?
Deadheading enables a plant to set additional flower buds for continued flowering and also stops the plant from self-sowing in the garden. It is the act of removing the old, wasted blooms. Any time the blooms start to wilt during the flowering season, blanket flowers benefit from deadheading.
Deadhead blanket flower plants by pinching back the flower stalks to the uppermost leaf to eliminate the complete floral structure. Inspect the plants at least once a week. Allowing the plant to set seeds uses energy that could be used to produce more blooms. By stopping this energy waste, deadheading, a plant may produce more flowers and be healthier.
How should Gaillardia be cared for?
In well-draining soil, scatter seeds and lightly cover them. Although they may withstand drought once established, blanket flowers require maintenance such as keeping the seeds moist until germination. Once established, routine watering should be incorporated into the maintenance of blanket flowers. This helps to extend the time that the vibrant blooms are on show.
To take good care of blanket flowers, place them where they will receive direct sunlight. The blanket flower is a heat-loving bloom that thrives in Mexico and the central United States. It also draws butterflies. Growing blanket flowers is drought resistant, however they do not appreciate muddy, damp feet. Additionally, they are highly tolerant of the cold and can typically endure temperatures as low as USDA zones 5 or even 3.
After becoming accustomed to producing blanket flowers, you can use them to provide vibrant color to a bed or border. Growing blanket flowers can provide color and naturalization to a field or meadow. The inexpensive maintenance of blanket flowers makes them a perfect exemplar for many landscape applications.
