White Flowers ( Thistles )
composite Family (Compositae)

White Thistle
Cirsium hookerianum

Season: Mid-July to Mid-August
Habitat:
 Disturbed Ground
Height:
 Up to 100 cm

Description: This common thistle generally grows as a biennial, spending one summer as a small clump of leaves, and storing energy in a large tap root before blooming the second summer. It can be easily identified by its typical thistle-like white bloom and sharp thorns. The white, shaggy flower-head grows atop a thorny ball. The leaves are alternate, lobed and sharply thorned, as is the thick stem. The entire plant is covered in dense white hairs. Despite its sharp armament, it is a common food source for local wildlife.
