Hymenoxys quinquesquamata Plant Care

Hymenoxys quinquesquamata (Hymenoxys quinquesquamata) belongs to the Asteraceae family within the Hymenoxys genus.

Hymenoxys quinquesquamata displays a low rosette, clumping growth habit, reaching up to 1 ft tall with a spread of approximately 1 ft. Hymenoxys quinquesquamata produces daisy-like yellow flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Hymenoxys quinquesquamata every 7–14 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.

Hymenoxys quinquesquamata thrives in full sun to partial shade.

Hymenoxys quinquesquamata tolerates temperatures of 50–80°F. Hymenoxys quinquesquamata prefers humidity levels of 30–60%.

Well-draining sandy soil mix with added organic matter. Good drainage is essential for Hymenoxys quinquesquamata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hymenoxys quinquesquamata 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 mix with added organic matter. Avoid low spots where water collects after rain.

Hymenoxys quinquesquamata 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.

Hymenoxys quinquesquamata 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 Hymenoxys quinquesquamata 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.

Hymenoxys quinquesquamata 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.

Hymenoxys quinquesquamata can be propagated through seeds, division of clumps. Similar propagation techniques also apply to bigelow's rubberweed plant care, which shares the same genus.

Hymenoxys quinquesquamata is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Hymenoxys quinquesquamata grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Hymenoxys quinquesquamata as a houseplant or bring it indoors before the first frost.
