After the flower head dries, the hooked bracts will attach to humans and animals to transport the entire seedhead. Characteristics ''Arctium minus'' can grow up to tall and form multiple branches. It is large and bushy. Flowers are prickly and pink to lavender in color. Flower heads are about wide. The plant flowers from July through October.

It is a twining plant of woodland verges and rough places with heart-shaped leaves and funnel-shaped white flowers with a pinkish throat. The large tuberous roots can be roasted and eaten, or can be used to make a poultice or infusion. When uncooked, the roots have purgative properties.Peterson, Lee, ''A Field Guide to Edible Wild Plants of Eastern and Central North America'', p. 20, Houghton Mifflin Company, New York City, accessed 22 November 2010.

picture info	Heracleum Mantegazzianum ''Heracleum mantegazzianum'', commonly known as giant hogweed, is a monocarpic perennial herbaceous plant in the carrot family Apiaceae. ''H. mantegazzianum'' is also known as cartwheel-flower, giant cow parsley, giant cow parsnip, or hogsbane. In New Zealand, it is also sometimes called wild parsnip (not to be confused with ''Pastinaca sativa'') or wild rhubarb. Giant hogweed is native to the western Caucasus region of Eurasia. It was introduced to Britain as an ornamental plant in the 19th century, and has also spread to other areas in Western Europe, the United States, and Canada. Its close relatives, Sosnowsky's hogweed and Persian hogweed, have similarly spread to other parts of Europe. The sap of giant hogweed is phototoxic and causes phytophotodermatitis in humans, resulting in blisters and scars. These serious reactions are due to the furanocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant. Consequently, it is considered to be a ...

	Rumex Hymenosepalus ''Rumex hymenosepalus'', commonly known as canaigre, canaigre dock, ganagra, wild rhubarb, Arizona dock, and tanner's dock, is a perennial flowering plant which is native to the North American deserts in the southwestern United States and northern Mexico. It is a common food plant of the ruddy copper larvae. Uses It has been cultivated in the southwestern United States for the roots, a good source of tannin, which is used in leather tanning. It also yields a warm, medium brown dye. The leaves and leaf stalks are considered edible when young, the older leaf stalks cooked and eaten like rhubarb, which is in the same plant family. Taxonomy ''Rumex hymenosepalus'' was first described by American botanist John Torrey John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician.
