タイトルまたは説明

:Milk thistle is described as an annual herb. A distinguishing characteristic of milk thistle is the white patches, or marbling found along the veins of the dark green leaves. The broad leaves are deeply lobed. The leaf margins are yellow and tipped with woody spines. The leaves are alternate, and clasping to the stem. Each stem ends in a solitary composite flower head, about two inches in diameter. The seeds are heavy, flat, smooth, and shiny and the color ranges from black to brown mottled. The seeds do have a tuft of minutely barbed bristles.
