Reproducing only by seed.
Smooth, leafless, succulent and round hollow stem that shows a milky substance when broken.
Leaves in a basal rosette. They are elongated, deeply and irregularly lobed along each side or sometimes just shallowly toothed with the amount and shape of lobing or toothing being extremely variable from one plant to another.
Flower heads bright yellow, 3.2-5cm across, borne singly on long, smooth, leafless, unbranched, hollow stalks which arise from among the rosette leaves. Only ray (strap-shaped) florets are present; outer row of involucral bracts short and spreading or bent down; seed heads white, more or less spherical, 3.5-5cm across. The seeds are long, slender with a slender beak tipped with a tuft of white hair (pappus or "parachute"). The whole plant contains sticky white juice. Flowers from early spring to late autumn.
Thick, deeply penetrating taproot.
Dandelion occurs throughout Ontario in virtually every kind of habitat, from openings in deep woods to cultivated fields, from rocky hillsides to fertile gardens, and lawns.
It is distinguished from other plants with milky juice and lobed or divided leaves in rosette stage by the soft texture and irregular lobing of leaves, the absence of prickles on margins or midribs, the smooth or softly hairy leaf surfaces, and a deeply penetrating taproot. Flowering plants are distinguished by their large yellow flower heads with only ray (strap-shaped) florets and borne singly on long, unbranched, leafless, hollow stalks which arise from among the rosette leaves, these followed by white, spherical seed heads up to 5cm in diameter.
Many songs have been written about dandelion, the most famous being by The Rolling Stones, http://www.youtube.com/watch?v=Zf0s3L8L7S0 to view a video of this song.
