A colorful, long-blooming wildflower, blanket flower earns its keep in the landscape with cheerful flowers in sunny shades of gold, orange, yellow and red. Most blanket flowers sold in garden centers are perennials and come back every year. With traits like deer- and rabbit-resistance, drought tolerance and the ability to thrive in lean, sandy soil, it's easy to see why blanket flower care is a cinch. This plant is one tough cookie.

Blanket flower is a North American native plant or wildflower. It goes by the botanical name Gaillardia, a plant group that includes a few key species. Gaillardia pulchella, the first species described in 1788, is an annual and opens 2-inch-wide red blooms with yellow tips. Explorers Lewis and Clark collected perennial Gaillardia aristata in Montana in 1806. It opens fringed flowers in red and yellow blends.

Today the most common type of blanket flower available is Gaillardia x grandiflora, a perennial that blends the best traits of the heirloom plants Gaillardia pulchella and Gaillardia aristata.

Where Do Blanket Flowers Grow Best?

Fuss-free to the core, blanket flower actually grows best in soil that's on the poor side. Sandy, fast-draining soil is ideal. Heavy or overly fertile soils won't grow the most gorgeous blanket flowers. In fact, soil that doesn't drain well is the top reason blanket flower dies. If your soil tends to be rich or heavy, you might get the best results growing blanket flower in containers.

How much sun does a blanket flower need? Blanket flower is a sun worshiper. Plants should receive at least six hours of sun each day, but more is better. Although blanket flower plants can grow in light shade, they'll have fewer flowers.

When to Plant Blanket Flower

In most regions, spring is the ideal time for planting blanket flowers. These plants thrive in heat, so wait until all danger of frost has passed. In USDA Zones 8 to 11 you can also plant blanket flower in the fall. Whenever you see plants for sale at local garden centers, that's a clue that it's planting time for your region.

It's possible to grow blanket flower from seed. Start with quality blanket flower seeds and wait for soil to warm up — definitely after any danger of frost has passed. Blanket flower seeds need light to germinate, so simply rough up soil before sowing, toss seeds onto the prepared area and keep it moist until seeds sprout. Blanket flower seeds typically take two to three weeks to germinate.

Most perennial blanket flowers bloom the same year they're planted, but you'll get a better flower show in subsequent years.

Caring for Blanket Flower

Water

Blanket flower is a prairie wildflower. Prairie plants typically boast terrific drought tolerance and deep tap roots. Blanket flower is no exception. While established plants don't need much watering, don't forget to water for the first few weeks after planting if rainfall is scarce. Once you see steady new growth, reduce watering and rely on rainfall to keep plants irrigated.

Blanket flowers in pots usually need watered daily by the time summer heat arrives. Plan to water plants when soil is dry to the touch to the middle knuckle of your index finger.

Keeping a 2- to 3-inch-thick mulch layer on the soil around the base of your blanket flower helps soil retain moisture and reduces weed seed germination. Use an organic mulch, such as triple shredded bark, pine needles, fir bark fines or whatever is locally available in your region.

Feeding

Once blanket flower plants are established in your landscape, they don't need much fertilizer. For established perennial blanket flower plants, fertilize in spring as new growth begins. You can accomplish this ideally by adding a 1- to 2-inch-thick layer of compost around plants or applying a commercial fertilizer for perennials. For newly planted blanket flowers in planting beds, fertilize at planting time by mixing a slow-release product into soil.

For blanket flowers in containers, mix a slow-release fertilizer into soil prior to planting. Choose a fertilizer with low numbers, such as 3-1-2, 6-2-4 or 9-3-6, and use it at half the rate suggested on the label. Plan to add more to the top of soil in six to eight weeks, gently scratching it into the soil. Skip bloom booster-type products.

Winter Care

As long as soil drainage is good, most blanket flower plants survive cold to -20° F without any extra mulch or even snow cover.

Do you cut back blanket flower in the fall? Many gardeners in coldest zones report improved winter survival by cutting blanket flower plants back to about 6 inches in late summer.

For blanket flower plants in containers, you have two options for overwintering.

Leave the plant in containers and shift them into an unheated garage or shed. Water occasionally through winter to keep roots alive.

The other choice is to transplant your blanket flowers into a planting bed or empty vegetable garden for winter. Aim to do this a minimum of six weeks prior to hard frost in your area. Once the ground freezes, mulch soil well.

Blanket Flower FAQs

Do I need to deadhead blanket flower?

Technically, no, you don't have to remove spent blanket flower blooms, but doing so will keep the plant from setting seed and may encourage more flowers to form. Near the end of the growing season, let some flowers go to seed for birds to eat and for you to sprinkle around the plant to increase the size of your blanket flower patch.

How long do blanket flowers last?

Blanket flowers are known as short-lived perennials. The average lifespan for Gaillardia x grandiflora varieties is about two years. Divide plants at the two-year mark to keep the clump strong. Plan to add new plants every few years, or simply scatter seed from existing blanket flowers in areas where you want them to grow.

Do blanket flowers spread?

Blanket flowers are not aggressive growers, but will spread by self-sowing (dropped seed sprouts and forms a new plant). Baby blanket flowers look like dandelions, so it's a good idea to learn to identify the seedlings so you don't accidentally pull them when weeding.

Is blanket flower a good ground cover?

Because blanket flower is a short-lived perennial, it's not a great choice for a flowering ground cover. Some varieties spread somewhat, so they can fill the role in that sense, but it's not long-lasting like creeping phlox or low growing sedum.
