Arizona gaillardia is also known by several common names, including desert gaillardia, Arizona blanketflower, and Pringle's gaillardia.
Uses
Arizona gaillardia has several uses in landscaping and gardening. Its bright yellow, daisy-like flowers with crimson centers make it a popular ornamental plant for rock gardens, borders, and container gardens. It is also a drought-tolerant and low-maintenance plant, making it ideal for xeriscaping.
In addition to its ornamental uses, Arizona gaillardia is also used in traditional Native American medicine to treat a variety of ailments, including fever, coughs, and sore throat.
General Appearance
Arizona gaillardia is a herbaceous perennial that grows to about 2 feet tall and 1 foot wide. It has an upright growth habit and produces a basal rosette of lance-shaped leaves that are up to 6 inches long. The stems are long and slender, with numerous branching stems that end in single flowers.
The flowers themselves are showy, with yellow petals that are often tipped with red or orange. The center disk is dark red or maroon and is surrounded by several rings of light-colored bracts. The flowers bloom from late spring to early fall and are followed by seedheads that are attractive to birds.

Light Requirements
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake typically grows in full sun to part shade. This plant requires at least six hours of direct sunlight to grow and flower properly. In areas with hot and dry summers, it grows best in partial shade to avoid heat stress.
Temperature Requirements
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake is a heat-loving plant and grows well in warm temperatures. The ideal temperature for its growth ranges between 60°F to 80°F (15°C to 27°C). This plant is drought-tolerant and can withstand high temperatures and low moisture levels. In colder regions, this plant may require winter protection such as mulching.
Soil Requirements
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake prefers well-drained, sandy or loamy soil with a pH range between 5.5 to 7.5. This plant is adaptable to various soil types, but it is not suitable for heavy clay soils that retain water, which can lead to root rot. Before planting, it is recommended to amend the soil with organic matter such as compost to improve its fertility and drainage.
Cultivation methods
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake prefers a sunny location with well-drained soil. It is tolerant of dry spells and drought but needs regular watering during the growing season to flourish. This plant is easy to grow and maintain and can be propagated by seeds or division.
Watering needs
Watering should be done when the soil surface is dry to the touch. This plant does not require frequent watering, but regular watering during hot and dry weather is necessary. Overwatering can cause the roots to rot, so it’s best to err on the side of underwatering.
Fertilization
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake does not require much fertilization. A single dose of a balanced fertilizer in spring is sufficient to supply nutrients to the plant. Avoid over-fertilizing the plant, which can result in the growth of too much foliage and fewer flowers.
Pruning
Pruning is not necessary for this plant, but deadheading can help to prolong the blooming season. Deadheading is the process of removing spent flowers and encourages the plant to produce more blooms. Cut the stems just below the flower head to remove the spent flowers. If the plant becomes too tall and leggy, it can be cut back by one third to encourage new growth.
Propagation of Gaillardia arizonica Gray var. pringlei (Rydb.) Blake
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake, commonly known as Arizona Gaillardia, is a hardy perennial plant that belongs to the sunflower family. This plant is usually propagated through seeds or vegetative propagation.
Propagation by seed
Propagation of Gaillardia arizonica is most commonly performed by seed. The seeds of this plant have a hard outer coat that needs to be scarified before planting. Scarification can be done by letting the seed coat soak in hot water for 24 hours or by mechanically scratching the seed coat. Once scarified, the seeds can be sown in a well-draining soil mix. It is best to sow the seeds in the spring or fall.
The seeds should be sown a few inches apart and covered with a thin layer of soil. Keep the soil moist but not waterlogged. Germination usually occurs within 2-3 weeks, although it can take as long as a month. Once the seedlings have grown large enough to handle, they can be transplanted into individual pots or directly into the ground.
Propagation by division
Propagation by division is another method to propagate Gaillardia arizonica. This method involves dividing the clumps that form as the plant grows older. The best time to perform division is in the spring or fall.
The clump should be dug up carefully and then divided into smaller sections, making sure that each section has a good root system. These sections can then be replanted into pots or directly into the soil. It is important to keep the soil moist until the plant has become established.
Propagation by division is a good way to maintain a desirable form of the plant and also to rejuvenate older plants that may have become too leggy.
Disease and Pest Management for Gaillardia arizonica Gray var. pringlei (Rydb.) Blake
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake, commonly known as Arizona Gaillardia, is a wildflower native to the southwestern United States. While this plant is typically resistant to pests and diseases, there are a few issues that can arise and require management techniques.
Common Diseases
One common disease that can affect Gaillardia arizonica is powdery mildew, which is a fungal disease that causes a white, powdery coating to appear on the leaves and other parts of the plant. To manage powdery mildew, avoid overhead watering and provide good air circulation around the plant. Use a fungicidal spray if necessary.
Another disease that can impact this plant is root rot, which is caused by a waterborne fungus. Root rot can occur when the plant is overwatered or the soil doesn't drain properly. To manage root rot, improve soil drainage and water the plant sparingly.
Common Pests
There are a few pests that can affect Gaillardia arizonica, including spider mites and aphids. Spider mites are small insects that feed on the plant's foliage, causing leaves to turn yellow and become stippled with discoloration. To manage spider mites, spray the plant with a strong stream of water or use an insecticidal soap.
Aphids are another pest that can impact this plant, causing foliage to curl and distort. These small, soft-bodied insects can be managed by spraying the plant with a strong stream of water or using insecticidal soap. Introducing natural predators like lady beetles can also help control aphid populations.
Conclusion
Gaillardia arizonica Gray var. pringlei (Rydb.) Blake is a hardy plant that is resistant to most pests and diseases. However, powdery mildew, root rot, spider mites, and aphids can all impact this plant at times. By implementing proper management techniques, including providing good air circulation, improving soil drainage, and using insecticidal soap or natural predators, it is possible to keep your Arizona Gaillardia healthy and thriving.
