Chlorocrepis tristis Plant Care

Chlorocrepis tristis (Pilosella tristis) belongs to the Asteraceae family within the Pilosella genus. Chlorocrepis tristis is native to North America. Chlorocrepis tristis is also known as Hieracium gracile, Hieracium gracile var. alaskanum, Hieracium gracile var. densifloccosum.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Chlorocrepis tristis 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.

Chlorocrepis tristis thrives in full sun to part shade.

Pilosella tristis tolerates temperatures of 50–75°F. Chlorocrepis tristis prefers humidity levels of 40–70%.

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

Feed Chlorocrepis tristis 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 part shade and well-draining sandy soil mix with some organic matter. Avoid low spots where water collects after rain.

Chlorocrepis tristis 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.

Chlorocrepis tristis 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 Chlorocrepis tristis 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.

Chlorocrepis tristis 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.

Chlorocrepis tristis can be propagated through seeds, division of offsets. Similar propagation techniques also apply to chlorocrepis albiflora plant care, which shares the same genus.

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

Chlorocrepis tristis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Chlorocrepis tristis is native to North America. In cooler regions, grow Chlorocrepis tristis as a houseplant or bring it indoors before the first frost.
