Synonyms (former Scientific Names):
Seedlings have round to oval shaped cotyledons, and then develop a basal rosette of oval shaped leaves with toothed margins. Mature plants of the second season have angled stems with parallel lines and downward pointing spines.
The opposite leaves are lanceolate to elliptic in shape. Basal leaves die early in the second year once the erect stem is produced. Leaves are prickly along the midrib on the underside of the leaf. The leaf margins are largely non-toothed.
This plant is easily recognized by spiny flower heads that remain throughout the year, which are often used in floral arrangements.
