Red-purple gaillardia Plant Care

Red-purple gaillardia (Gaillardia pinnatifida) belongs to the Asteraceae family within the Gaillardia genus. Red-purple gaillardia is native to northern Mexico and in the south-central and southwestern United States. Red-purple gaillardia is also known as Red gaillardia, Gaillardia flava, Gaillardia gracilis.

Red-purple gaillardia displays a low rosette, clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. Red-purple gaillardia produces colorful daisy-like flowers in red, yellow, and orange hues.

Leaf size: approximately 4 inches.

Water a young or newly planted Red-purple gaillardia every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Red-purple gaillardia thrives in full sun to partial shade.

Gaillardia pinnatifida tolerates temperatures of 60–80°F. Red-purple gaillardia prefers humidity levels of 40–60%.

Well-draining, sandy soil with some organic matter. Good drainage is essential for Red-purple gaillardia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Red-purple gaillardia every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining, sandy soil with some organic matter. Avoid low spots where water collects after rain.

Red-purple gaillardia is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Red-purple gaillardia can spread to about 2 ft (0.5 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Red-purple gaillardia while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Red-purple gaillardia is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Red-purple gaillardia can be propagated through seeds, division of clumps. Similar propagation techniques also apply to firewheel plant care, which shares the same genus.

Red-purple gaillardia is susceptible to aphids, spider mites, powdery mildew. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Red-purple gaillardia grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Red-purple gaillardia is native to northern Mexico and in the south-central and southwestern United States. In cooler regions, grow Red-purple gaillardia as a houseplant or bring it indoors before the first frost.
