Thistle - Thistle

Japanese: アザミ(薊) - アザミ

It is a genus of the Asteraceae family and has about 200 species, of which about 80 are native to Japan. Most are perennials, but some are biennials. It is widely distributed in the warm to cold zones of the Northern Hemisphere, growing from the coast to the high mountains. The leaves are sawtoothed or pinnately lobed, have sharp prickles, and some have dense goosebumps on the underside. The involucre consists of multiple rows of involucre segments, and the shape and arrangement of the segments often characterize the species. The flower heads consist of many tubular flowers, and most of them bloom in autumn. In addition to the magnificent Fuji thistle, Noa thistle has upright red-purple flower heads about 4 cm in diameter that bloom in spring and summer and are distributed south of Honshu. Onia thistle, which blooms from early summer to autumn, is found in the northern Chubu region and Tohoku region, and has drooping deep purple flower heads. Sea thistle, which grows on the sandy coasts of the Izu Islands and the Izu Peninsula on the Pacific coast, has upright flower heads and shiny leaves. In general, the roots of many species are edible, and Mori thistle in particular is cultivated, and its roots are called mountain burdock or chrysanthemum burdock and are pickled in sake lees. Ageratum, fox thistle, and artichoke are all separate genus from thistle.
