How to Grow and Care for Blanket Flower: Growing Methods and Precautions

Light and Temperature

Blanket flower loves sunlight and is highly tolerant of high temperatures and heat, but it is not very cold-hardy. Its most suitable growing temperature is 15°C-35°C. During its growth period, ensure sufficient sunlight; it can also grow in semi-shaded environments. Sunlight requirements: full sun.

Soil

Blanket flower has fairly strict soil requirements. The soil should be loose, breathable and well-draining. Note that the soil pH should not be on the acidic side, as this is detrimental to the plant's growth. The soil blanket flower needs can be mixed yourself or you can buy specialized soil from a flower shop.

Watering and Fertilizing

Blanket flower needs a fair amount of fertilizer. It is also quite drought-tolerant and afraid of waterlogging, but be careful to maintain the humidity around the plant. Generally, fertilizing and watering blanket flower should follow the principle of small amounts applied frequently. Especially during the growing season, fertilize it early; you can apply more phosphorus and potassium fertilizers. After fertilizing, keep the plant dry. Also, strictly control watering and fertilizing when the plant is blooming.

The above covers how to grow blanket flower. Now let's look at what to pay attention to when growing blanket flower.

Introduction to Blanket Flower

Blanket flower(scientific name:Gaillardia pulchella), also known asGaillardia pulchella、Tiger-stripe Gaillardia(Shanghai),Center Gaillardia、Centaurea blanket flower, is a plant in the genus Gaillardia of the Asteraceae family. It is distributed in North America, tropical America, and the American continent. It is native to central United States and is an annual plant with a very short growing period. It has now been introduced and cultivated artificially.

Blanket flower is the state flower of Oklahoma in the United States, and also the county flower of Penghu County, Taiwan Province, China.
Blanket flower is tolerant of drought and heat, not cold-hardy, loves sunlight, and also tolerates semi-shade. It prefers loose, well-draining soil. Blanket flower is wind-resistant, moisture-resistant, and highly resilient with drought-tolerant characteristics. It is an excellent windbreak and sand-fixing plant.

Morphological Characteristics of Blanket Flower

Blanket flower is an annual herbaceous plant. The plant is about 20-60 cm tall, covered with soft hairs throughout. Leaves are alternate, lanceolate, oblong to spatulate, with entire margins or pinnately lobed basal leaves. Petal-like; ray florets are yellow at the tip and brownish-purple at the base. Flowering period is summer and autumn.
The cultivated variety of blanket flower, Centaurea blanket flower, has ray florets and even the tubular florets in the center of the flower head developed into funnel shapes. There are large-flowered and red-flowered varieties.
Blanket flower blooms from July to October, and the fruit ripens from August to October.
The flower of blanket flower is a "capitulum" (head). A "single flower" is actually "a bouquet of flowers" because it contains many ray florets and tubular florets. The colorful ray florets on the outside are like a landing pad attracting insects; the tubular florets in the center look like small round balls. After the ray florets wither, this part develops into a seed cluster, and the seeds inside are then dispersed by the wind and grow where they land. In addition, some blanket flower ray florets grow into tube shapes, looking like curved little trumpets; some varieties of blanket flower have entire flowers in tender yellow, with a unique charm; and the leaves and soft hairs of blanket flower are also worth observing.

Ecological Habits of Blanket Flower

Blanket flower prefers high temperatures, dry conditions and full sunlight. It has good salt tolerance, strong wind resistance, good drought tolerance, good cold tolerance, and slightly poor shade tolerance.
Blanket flower is native to North America. It is tolerant of drought and heat, not cold-hardy, loves sunlight, and also tolerates semi-shade. It prefers loose, well-draining soil. It is wind-resistant, moisture-resistant, and highly resilient with drought-tolerant characteristics, making it an excellent windbreak and sand-fixing plant. If grown in acidic soil, it will not only be difficult to obtain strong seedlings, but the lower leaves will wither in midsummer. It grows rapidly, so fertilizer should be applied early, and the phosphorus-to-potassium ratio should be somewhat higher.

Cultivation Techniques for Blanket Flower

Blanket flower has good cold tolerance and no special soil requirements, though sandy soil and well-draining soil are most suitable for its growth, and it dislikes moisture. It has very good drought tolerance and can grow well in sunny, dry and hot climates. From summer to late autumn, it is commonly seen in grassy fields and along roadsides stretching for miles. In horticulture, removing flower buds can promote further blooming of blanket flower. In winter, the above-ground parts wither, and the roots remain underground to overwinter, sprouting again in spring.

Blanket flower can be propagated by seeding, division, and cuttings, while root cuttings require a certain level of skill.

Many cultivated varieties of blanket flower have been bred, mainly those with red and yellow alternating halo-like flower discs. A recently bred cultivar, "Sundance Bicolor," has flower heads with alternating red and yellow colors. Because of its bright colors, it is suitable for planting in sunlight. This cultivar's flower shape is very similar to that of the Chrysanthemum genus. The Plume series of blanket flower has double-petaled flowers, similar to cornflowers.

Propagation by Seeding
Seeding is often done in summer. Sterilize the seeding substrate; the best method is to put it in a pot and heat it by stir-frying, which will kill any pests or diseases. Soak the seeds in warm water (temperature similar to face-washing water) for 3-10 hours until the seeds absorb water and swell. For very common seeds that germinate easily, this step can be skipped. For tiny seeds that are difficult to pick up with hands or other tools, moisten one end of a toothpick with water and stick the seeds one by one onto the surface of the substrate, then cover with 1 cm of substrate. Then place the seeding pot into water, with the water depth at 1/2 to 2/3 of the pot's height, allowing water to slowly soak up. For larger seeds that can be picked up by hand or other tools, place the seeds directly into the substrate, sowing at 3×3 cm spacing. After sowing, cover with substrate to a thickness of 2-3 times the seed size. After sowing, use a spray bottle or fine-holed watering can to moisten the seeding substrate. Later, when the pot soil is slightly dry, water again. Still be careful not to water too forcefully, to avoid washing the seeds away. Post-sowing management: After the seedlings emerge, promptly remove the plastic film, and let the seedlings receive sunlight before 9:30 AM or after 3:30 PM each day, otherwise the seedlings will grow very weak. After most seeds have germinated, thin the seedlings appropriately: pull out diseased and unhealthy seedlings, leaving the remaining seedlings with some space between each other. When most seedlings have grown 3 or more leaves, they can be transplanted into pots.

Propagation by Cuttings
The branches used for cuttings are called cuttings. Usually combined with pinching, the thick, pest-free and disease-free terminal shoots that are removed are used as cuttings, directly using the terminal shoots for cutting. After cutting, the following management points should be noted: Temperature: The optimal temperature for cutting rooting is 18°C-25°C. Below 18°C, rooting is difficult and slow; above 25°C, the cut end of the cutting is prone to infection by pathogens and rot, and the higher the temperature, the greater the proportion of rot. When low temperatures are encountered after cutting, the main measure for warmth is to wrap the pot or container used for cutting with plastic film. When temperatures are too high after cutting, the main measure for cooling is to shade the cuttings, blocking 50-80% of sunlight, and at the same time, mist the cuttings 3-5 times a day. On sunny days with higher temperatures, mist more frequently; on cloudy and rainy days with lower temperatures and higher humidity, mist less or not at all.
Transplanting
When potting small seedlings, first place 2-3 cm of coarse-grained substrate or expanded clay at the bottom of the pot as a drainage layer, then sprinkle a layer of fully decomposed organic fertilizer as base fertilizer, about 1-2 cm thick, then cover with another layer of substrate, about 1-2 cm thick, and then place the plant in, so as to separate the fertilizer from the roots and avoid burning the roots. The substrate for potting can be one of the following. Garden soil: cinder = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud, or leaf mold. Or peat + perlite + expanded clay = 2 parts + 2 parts + 1 part; garden soil + cinder = 3 parts + 1 part; peat + cinder + expanded clay = 2 parts + 2 parts + 1 part; sawdust + vermiculite + medium-coarse river sand = 2 parts + 2 parts + 1 part. After potting, water thoroughly once and place in a slightly shaded environment for one week of care. When transplanting small seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as base fertilizer, about 4-6 cm thick, then cover with a layer of soil and place the seedling in, so as to separate the fertilizer from the roots and avoid burning the roots. After placing the seedling, backfill the soil to cover the roots, and press the soil firm with your foot, then water thoroughly once. Before flowering, generally pinch twice to encourage more flowering branches. One to two weeks after potting, or when the seedling is 6-10 cm tall and has six or more leaves, remove the terminal shoot, keeping the lower 3-4 leaves, to encourage branching. Three to five weeks after the first pinching, or when the side branches grow to 6-8 cm long, perform the second pinching, removing the terminal shoots of the side branches and keeping the lower 4 leaves of the side branches. After two pinchings, the plant shape will be more ideal and the number of flowers will be greater.

Management and Care of Blanket Flower

Humidity Management
It prefers higher air humidity. If air humidity is too low, individual flowers will wither faster. It also dislikes rain, and leaves need to stay dry at night. The optimal relative air humidity is 65-75%.
Temperature Management
Heat-tolerant, not frost-tolerant.
Light Management
Loves full sunlight, slightly tolerant of semi-shade.
Fertilizer and Water Management
Like other herbaceous flowers, blanket flower has relatively high fertilizer and water requirements, but the fertilizing (and watering) principle of "light fertilizer applied frequently, small amounts with more frequent applications, complete nutrition" should be followed. After fertilizing, keep the leaves and flowers dry at night:
Summer and autumn: This is its peak growing season. Fertilizer and water management follows the cycle of "Hua Bao" - "Hua Bao" - clear water - "Hua Bao" - "Hua Bao" - clear water (at minimum, ensure two applications of "Hua Bao" per week). After entering the flowering period, appropriately reduce fertilizer to help the seeds mature.

Distribution Area of Blanket Flower

Blanket flower is native to central United States and is an annual plant with a very short growing period. It has now been introduced and cultivated artificially.

Blanket flower is distributed in North America, tropical America, and the American continent.

Landscape Uses of Blanket Flower

Blanket flower is an excellent herbaceous plant for sand greening, beautification, and sand fixation. Its flowers are charming, colorful, with a long flowering period and simple cultivation and management. It can be used as material for flower beds and flower clusters.
Tending management: The best cultivation soil is loam or sandy loam. Good drainage and sunlight are required. If sunlight is insufficient, flowering will be poor. Fertilize once a month. The suitable growing temperature is 10-25°C.

Cultural Background of Blanket Flower

County Flower of Penghu County

Blanket flower is the county flower of Penghu County, Taiwan Province, China. It can be seen everywhere in Penghu, which is why Penghu is called the "Island of Chrysanthemums."

The entire blanket flower plant has soft hairs that can prevent water loss, which is the main reason blanket flower can survive in harsh environments.
Blanket flower's leaves are slender, and its flowers are yellow and red bicolor, with a few being golden yellow. The flower stems are long and upright; seeds are dispersed by the wind and grow where they land.
It can withstand wind, tolerate drought, resist moisture, and is highly resilient. It is an excellent windbreak and sand-fixing plant.

Due to its strong reproductive capacity and vitality, after being introduced from North America, blanket flower grew vigorously at an astonishing rate in the Penghu archipelago and along the central and northern coasts of Taiwan. Today, the beautiful blanket flower has become one of the scenic attractions of Penghu tourism, and because of its resilient qualities, it was chosen as the county flower of Penghu.

II. Growing Methods for Blanket Flower

1. Habits: Blanket flower is heat-tolerant, drought-tolerant and cold-tolerant, loves sun, dislikes waterlogging, and has a long growth period.

2. Propagation: Blanket flower is usually propagated by seeding, cuttings, division, and other methods. Seeding can be done in both spring and autumn. Seeds emerge in 10-15 days at 20°C, and are transplanted when they grow to 6 true leaves. Division can also be done in spring and autumn: dig up healthy plants and divide them from the base into several clumps with a certain amount of fibrous roots, and plant promptly. Cuttings are divided into green-wood cuttings and root cuttings. For green-wood cuttings, young shoots in early summer are best; for root cuttings in summer, take root segments about 15-20 cm from the root crown, and new shoots will sprout for planting.

3. Cultivation: In terms of cultivation measures for blanket flower, attention should be paid to applying sufficient base fertilizer, spraying flower fertilizer, digging trenches for drainage, pinching to promote branching, and promptly removing spent flowers, etc., to promote growth and development. Planting spacing: 30-40 cm or 50-60 cm.

4. Flowering period management: During the flowering period of blanket flower, keep the substrate moist. Lack of water will shorten the flowering period. Especially during the peak flowering period, promptly and specifically replenish water to keep the perennial blanket flower moist.
