Characteristics

  • Leaves: Basal leaves are pinnatifid (deeply lobed) and rough-hairy; stem leaves are smaller, lanceolate, and clasp the stem with sagittate bases.
  • Flowers: Inflorescence is a corymb-like cluster of capitula (flower heads); each head is 2 - 3.5 cm across, composed entirely of yellow ligulate (ray) florets.
  • Stem: Erect, grooved, branched in the upper half, often purplish near the base, and covered with stiff, rough hairs.
  • Fruit: Yellowish-brown achenes, 10-13 ribbed, narrowing at the apex but lacking a distinct beak, topped with a pure white, unbranched pappus.

Care Guide

Watering

Water moderately during active growth and blooming phases if rainfall is insufficient.

Fertilization

Rarely requires fertilization; a light top-dressing of compost can be applied.. As a wild meadow plant, it thrives in relatively low-nutrient soils.

Eggshell powder:Crush clean, dry eggshells into a fine powder and sprinkle around the base to support cellular growth without over-fertilizing.
Pruning
  • Deadhead spent flowers to prevent aggressive self-seeding if grown in a controlled garden setting.
  • Cut back the entire stalk to the basal rosette after the flowering season ends.
  • Remove damaged or diseased basal leaves to improve air circulation.
