Pilosella Plant Care
Pilosella lactucella (Wallr.) P.D.Sell & C.West
Updated · Sources · How we source care data
Pilosella lactucella (synonym Hieracium lactucella, also called European hawkweed) is a species of perennial plant from the family Asteraceae, found in Europe, New York (United States) and Nova Scotia (Canada). It is 9–20 centimetres (3.5–7.9 in) in height, with stems from 1–2 millimetres (0.039–0.079 in) wide. The leaves are spatula shaped and 5–8 centimetres (2.0–3.1 in) wide. The flowers bloom from May to July, the heads of which are 2–5 centimetres (0.79–1.97 in) tall. It was once described by Carl Linnaeus as Hieracium auricula and Pilosella auricula, but was recategorized by A. E. Roland and M. Zinck in 1998.

How do you care for Pilosella?
Plant Pilosella in full sun to part shade (USDA zones 12a) and water a young shrub every 7–10 days until it is established. It tolerates temperatures of 50–75°F (10–24°C). Fertilize it every 6 months during the growing season.

What Is the Pilosella?
Pilosella (Pilosella lactucella) belongs to the Asteraceae family within the Pilosella genus. Pilosella is native to Europe, New York and Nova Scotia (Canada).
Pilosella displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Pilosella produces small yellow daisy-like flowers in clusters.
Leaf size: approximately 2 inches.
How Often Should You Water a Pilosella?
Water a young or newly planted Pilosella 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.

What Light Does the Pilosella Need?
Pilosella thrives in full sun to part shade.

What Temperature and Humidity Does the Pilosella Prefer?
Pilosella lactucella tolerates temperatures of 50–75°F. Pilosella prefers humidity levels of 40–70%.

What Soil Mix Works Best for a Pilosella?
Well-draining sandy soil mix with some organic matter. Good drainage is essential for Pilosella to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Pilosella?
Feed Pilosella 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.
Where Should You Plant a Pilosella?
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.
Pilosella 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.
How Far Apart Should You Plant a Pilosella?
Pilosella 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.

How Do You Prune a Pilosella?
Prune Pilosella 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.
How Do You Care for a Pilosella in Winter?
Pilosella 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.
How Do You Propagate a Pilosella?
Pilosella can be propagated through seeds, division of offsets. Similar propagation techniques also apply to chlorocrepis albiflora plant care, which shares the same genus.
Is the Pilosella Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Pilosella, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What Pests and Diseases Affect the Pilosella?
Pilosella 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.

What USDA Hardiness Zone Does the Pilosella Need?
Pilosella grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Pilosella is native to Europe, New York and Nova Scotia (Canada). In cooler regions, grow Pilosella as a houseplant or bring it indoors before the first frost.
