The Story
Plant Bio
Urospermum picroides is an erect annual or biennial herb characterized by its bristly, rough-textured stems and deeply lobed, sharp-toothed leaves. The plant produces solitary, pale yellow to golden yellow flower heads composed entirely of strap-shaped ray florets enclosed by bristly bracts.
This species is highly adaptable, thriving in poor, dry soils and coastal conditions where many other herbaceous plants struggle. Its seeds feature a distinctive hollow-tailed pappus that facilitates highly efficient wind dispersal over wide areas.

Planting
How to Grow
- Sow seeds directly into well-drained soil in a location receiving full sun during early spring.
- Keep the soil lightly moist until germination occurs, after which the taproot will establish quickly.
- Withhold supplemental fertilizers, as the plant thrives and develops sturdier stems in nutritionally poor soils.
- Monitor the developing flower heads closely and remove them before they transition into fluffy seed heads.
Pro Tip
Prevent seed dispersal by hand-pulling or cutting the plants down to the taproot before the flower heads mature and release their wind-borne achenes.

Care Guide
Do
- Grow in full sun to ensure upright growth and prevent the stems from flopping.
- Ensure the soil is well-drained to prevent root rot in wet winter conditions.
- Wear gloves when handling the foliage to avoid mechanical irritation from the stiff, bristly hairs.
Don't
- Do not apply supplemental fertilizer, which promotes excessive, weak vegetative growth.
- Do not prune or cut back into old, leafless wood, as this annual or biennial cannot regenerate from woody tissue.
- Do not allow the plant to set seed if you wish to contain its spread in the garden.

Not reliably. Deer may browse Prickly Goldenfleece, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Prickly Goldenfleece bloom?
Prickly Goldenfleece typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Prickly Goldenfleece need full sun?
Prickly Goldenfleece does best in full sun (6+ hours).
Is Prickly Goldenfleece drought tolerant?
Yes — once established (usually after the first full season), Prickly Goldenfleece handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
