Galactites tomentosus, the purple milk thistle, is a biennial herbaceous plant belonging to the genus Galactites of the Asteraceae family.
Description
Galactites tomentosus is a hemicryptophyte plant up to 1 metre (3 ft 3 in) tall. The stem is erect and pubescent, branched at the top. The leaves are green, long and pinnatisect, lanceolate, mottled with white markings, while the underside is whitish and covered with matted woolly hairs. The margins of the leaves bear strong thorns.
The flower heads are quite large – about 3 centimetres (1.2 in) in diameter. The involucre of the flower head is covered by hairy scales ending with a single grooved thorn. The central flowers are hermaphrodite and are pollinated by insects, while external flowers are sterile; their color varies from white or pink to lilac-purple.
The flowering period extends from April through July and the seeds ripen from August through September. The fruits are achenes with whitish hairy appendages (pappus).
