What Do You Mean by Taraxacum Weed Plant?

Taraxacum is a big genus of flowering plants in the family Asteraceae, which contains species often called dandelions. The genus is native to Eurasia and North America, however the two commonplace species worldwide, T. officinale and T. erythrospermum, were introduced from Europe and now propagate as wildflowers. Both species are edible of their entirety. You can purchase cheap weed online by visiting this link.

Let’s Try To Understand What isĀ  Taraxacum Weed Plant?

The common name dandelion is given to members of the genus. Like other family Asteraceae, they have tiny flowers collected together in to a composite flower head. Each single flower in a head is named a floret. Partly because of the abundance along with being truly a generalist species, dandelions are the most vital early spring nectar sources for a wide host of pollinators. Many Taraxacum species produce seeds asexually by apomixis, where in fact the seeds are produced without pollination, resulting in offspring that are genetically identical to the parent plant.

The species of Taraxacum are tap-rooted, perennial, herbaceous plants, native to temperate regions of the Northern Hemisphere. The genus contains many species, which frequently (or regarding triploids, obligately) reproduce by apomixis, resulting in many local populations and endemism. In the British Isles alone, 234 microspecies are recognised in nine loosely defined sections, which 40 are “probably endemic”.

Generally, the leaves are 5-25 cm long or longer, simple, lobed, and form a basal rosette above the central taproot. The flower heads are yellow to orange coloured, and are also open in the daytime, but closed at night time. The heads are borne singly on a hollow stem (scape) that is normally leafless and rises 1-10 cm or even more above the leaves. Stems and leaves exude a white, milky latex when broken. A rosette may produce several flowering stems concurrently. The flower heads are 2-5 cm in diameter and consist completely of ray florets. The flower heads mature into spherical seed heads sometimes called blowballs or clocks (in both British and American English) containing many single-seeded fruits called achenes. Each achene is mounted on a pappus of fine hair-like material which permits wind-aided dispersal over long distances.

The flower head is surrounded by bracts (sometimes mistakenly called sepals) in two series. The inner bracts are erect until the seeds mature, then flex downward allowing the seeds to disperse. The outer bracts tend to be reflexed downward, but remain appressed in plants of the sections Palustria and Spectabilia. Some species drop the “parachute” from the achenes; the hair-like parachutes are called pappus, plus they are modified sepals. Between your pappus and the achene is a stalk called a beak, which elongates as the fruit matures. The beak breaks far from the achene very easily, separating the seed from the parachute.
