Texas Super Sunflower Plant Care

Texas Super Sunflower (Engelmannia texana) belongs to the Asteraceae family within the Engelmannia genus. Texas Super Sunflower is native to the south-central United States, primarily from Texas, New Mexico, Oklahoma, and southeastern Colorado. Texas Super Sunflower is also known as Yellow Daisy, Engelmann's Daisy.

Texas Super Sunflower displays a low rosette, clumping growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Texas Super Sunflower produces small yellow daisy-like flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Texas Super Sunflower 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.

Texas Super Sunflower thrives in full sun to partial shade.

Engelmannia texana tolerates temperatures of 50–85°F. Texas Super Sunflower prefers humidity levels of 40–70%.

Well-draining sandy loam with good organic content. Good drainage is essential for Texas Super Sunflower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Texas Super Sunflower 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.

Choose a spot with full sun to partial shade and well-draining sandy loam with good organic content. Avoid low spots where water collects after rain.

Texas Super Sunflower is suited to USDA Zone 12a.

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.

Texas Super Sunflower can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Texas Super Sunflower 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.

Texas Super Sunflower is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Texas Super Sunflower can be propagated through seeds, division of clumps. Similar propagation techniques also apply to engelmann's daisy plant care, which shares the same genus.

Texas Super Sunflower grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Texas Super Sunflower is native to the south-central United States, primarily from Texas, New Mexico, Oklahoma, and southeastern Colorado. In cooler regions, grow Texas Super Sunflower as a houseplant or bring it indoors before the first frost.
