Taraxacum ({{IPAc-en|t|ə|ˈ|r|æ|k|s|ə|k|ə|m}}){{cite Merriam-Webster|Taraxacum}} is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions.

Like other members of the family Asteraceae, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a floret. In part due to their abundance, along with being a generalist species, dandelions are one of the most vital early spring nectar sources for a wide host of pollinators.{{cite web |url=https://theguardian.com/lifeandstyle/gardening-blog/2015/may/12/dandelions-pollinators-wildlife-garden |title=Let dandelions grow.

In general, the leaves are {{Measurement converter|5-25|cm|in|1}} long or longer, simple, lobed-to-pinnatisect, and form a basal rosette above the central taproot. The flower heads are yellow to orange coloured, and are open in the daytime, but closed at night. The heads are borne singly on a hollow stem (scape) that is usually leafless and rises {{Measurement converter|1-10|cm|in|1}} or more above the leaves. Stems and leaves exude a white, milky latex when broken. A rosette may produce several flowering stems at a time. The flower heads are {{Measurement converter|2-5|cm|in|1}} in diameter and consist entirely of ray florets. The flower heads mature into spherical seed heads sometimes called blowballs{{cite web |url=http://encyclopedia2.thefreedictionary.com/blowball |title=blowball |author= |year=2003 |work=McGraw-Hill Dictionary of Scientific & Technical Terms |edition=6th |publisher=McGraw-Hill Companies |access-date=2013-01-26}} or clocks (in both British and American English){{cite Collins Dictionary|blowball}}{{cite encyclopedia |url=https://dictionary.infoplease.com/blowball |title=blowball |encyclopedia=InfoPlease Dictionary}}{{cite web |url=https://ldoceonline.com/dictionary/dandelion-clock |title=dandelion clock |work=Longman English Dictionary Online |publisher=Pearson |access-date=2019-06-02}}{{cite American Heritage Dictionary|clock}} containing many single-seeded fruits called cypselae, similar to achenes.

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 to allow the seeds to disperse. The outer bracts are often reflexed downward, but remain appressed in plants of the sections Palustria and Spectabilia. Between the pappus and the achene is a stalk called a beak, which elongates as the fruit matures. The beak breaks off from the achene quite easily, separating the seed from the parachute.{{Cite web |date=2022-06-01 |title=Engineers uncover secret 'thinking' behind dandelions' seed dispersal {{!}} Imperial News {{!}} Imperial College London |url=https://www.imperial.ac.uk/news/236934/engineers-uncover-secret-thinking-behind-dandelions/ |access-date=2024-05-13 |website=Imperial News |language=en}}
Description

The species of Taraxacum are tap-rooted, perennial, herbaceous plants, native to temperate areas of the Northern Hemisphere. The genus contains many species, which usually (or in the case of triploids, obligately) reproduce by apomixis, resulting in many local populations and endemism. In the British Isles alone, 234 microspecies (i.e. morphologically distinct clonal populations) are recognised in nine loosely defined sections, of which 40 are "probably endemic".{{cite book |url=https://books.google.com/books?id=nJ3YP28EjscC |title=New Flora of the British Isles |last=Stace|first=C. A. |publisher=Cambridge University Press |year=2010 |isbn=9780521707725 |edition=Third|location=Cambridge, U.K.|page=712|author-link=Stace, C. A.}} A number of species of Taraxacum are seed-dispersed ruderals that rapidly colonise disturbed soil, especially the common dandelion (T. officinale), which has been introduced over much of the temperate world. After flowering is finished, the dandelion flower head dries out for a day or two. The dried petals and stamens drop off, the bracts reflex (curve backwards), and the parachute ball opens into a full sphere. When development is complete, the mature seeds are attached to white, fluffy "parachutes" which easily detach from the seedhead and glide by wind, dispersing.
In Taraxacum ovules, the megaspore mother cell is the only cell committed to enter the meiotic process.Cornaro L, Banfi C, Cavalleri A, van Dijk PJ, Radoeva T, Cucinotta M, Colombo L. Apomixis at high resolution: unravelling diplospory in Asteraceae. J Exp Bot. 2025 Apr 9;76(6):1644-1657. doi: 10.1093/jxb/erae477. PMID: 39673465; PMCID: PMC11981899. Teraxacum officinale is able to reproduce by a sexual meiotic process involving the production of haploid gametes, as well as by an asexual parthenogenetic meiotic process, referred to as apomixis, that produces diploid seeds genetically identical to the mother plant. Parthenogenesis permits the autonomous development of an unreduced egg cell into an embryo without the requirement of fertilisation.
The seeds are able to cover large distances when dispersed due to the unique morphology of the pappus which works to create a unique type of vortex ring{{Cite journal|last1=Cummins|first1=Cathal|last2=Seale|first2=Madeleine|last3=Macente|first3=Alice|last4=Certini|first4=Daniele|last5=Mastropaolo|first5=Enrico|last6=Viola|first6=Ignazio Maria|last7=Nakayama|first7=Naomi|date=2018|title=A separated vortex ring underlies the flight of the dandelion|journal=Nature|volume=562|issue=7727|pages=414–8|doi=10.1038/s41586-018-0604-2|pmid=30333579|bibcode=2018Natur.562..414C|s2cid=52988814 |url=http://eprints.gla.ac.uk/171858/7/171858.pdf}}{{Cite journal|last1=Ledda|first1=P.

In addition to the creation of this vortex ring, the pappus can adjust its morphology depending on the moisture in the air. This allows the plume of seeds to close up and reduce the chance to separate from the stem, waiting for optimal conditions that will maximise dispersal and germination.{{Cite journal|title= Environmental morphing enables informed dispersal of the dandelion diaspore|last1=Seale|first1=Madeleine|last2=Zhdanov|first2=Oleksandr|date=2019-02-07|last3=Cummins|first3=Cathal|last4=Kroll|first4=Erika|last5=Blatt|first5=Michael R|last6=Zare-Behtash|first6=Hossein|last7=Busse|first7=Angela|last8=Mastropaolo|first8=Enrico|last9=Viola|first9=Ignazio Maria|journal=eLife |volume=11 |doi=10.7554/eLife.81962|doi-access=free |pmid=36445222 |pmc=9797189 |hdl=10044/1/102018|hdl-access=free}}{{Cite book|title=Investigating seed dispersal distances and long distance dispersal mechanisms of the invasive plant, Alliaria Petiolata|last=Loebach|first=Christopher A.|year=2015|publisher=Illinois State University |isbn=9781321782141|oclc=988948576}}

Many similar plants in the family Asteraceae with yellow flowers are sometimes known as false dandelions. Dandelion flowers are very similar to those of cat's ears (Hypochaeris). Both plants carry similar flowers, which form into windborne seeds. However, dandelion flowers are borne singly on unbranched, hairless and leafless, hollow stems, while cat's ear flowering stems are branched, solid, and carry bracts. Both plants have a basal rosette of leaves and a central taproot. However, the leaves of dandelions are smooth or glabrous, whereas those of cat's ears are coarsely hairy.{{rp|740}}
Early-flowering dandelions may be distinguished from coltsfoot (Tussilago farfara) by their basal rosette of leaves, their lack of disc florets, and the absence of scales on the flowering stem.{{cite book|last1=Blamey|first1=M.|last2=Fitter|first2=R.|last3=Fitter|first3=A|year=2003|title=Wild flowers of Britain and Ireland: The Complete Guide to the British and Irish Flora.|publisher=A & C Black|location=London|isbn=978-1408179505|page=274}}
Other plants with superficially similar flowers include hawkweeds (Hieracium) and hawksbeards (Crepis). These are readily distinguished by branched flowering stems, which are usually hairy and bear leaves.{{rp|740}}
Classification
The genus is taxonomically complex due to the presence of apomixis; any morphologically distinct clonal population would deserve its own microspecies. Phylogenetic approaches are also complicated by the accelerated mutation in apomixic lines and repeated ancient hybridisation events in the genus.
As of 1970, the group is divided into about 34 macrospecies or sections, and about 2000 microspecies;{{cite journal |author=A. J. Richards |year=1970 |title=Eutriploid facultative agamospermy in Taraxacum |journal=New Phytologist |volume=69 |issue=3 |pages=761–774 |jstor=2430530 |doi=10.1111/j.1469-8137.1970.tb02461.x|doi-access=free |bibcode=1970NewPh..69..761R }} some botanists take a much narrower view and only accept a total of about 60 (macro)species. By 2015, the number has been revised to include 60 sections and about 2800 microspecies. 30 of these sections are known to reproduce sexually.{{cite journal |last1=Kirschner |first1=Jan |last2=Záveská Drábková |first2=Lenka |last3=Štěpánek |first3=Jan |last4=Uhlemann |first4=Ingo |title=Towards a better understanding of the Taraxacum evolution (Compositae–Cichorieae) on the basis of nrDNA of sexually reproducing species |journal=Plant Systematics and Evolution |date=April 2015 |volume=301 |issue=4 |pages=1135–1156 |doi=10.1007/s00606-014-1139-0 |bibcode=2015PSyEv.301.1135K |s2cid=17903814 |url=https://www.researchgate.net/publication/265346629}}

Etymology
The Latin name Taraxacum derives from the Arabic {{lang|ar-Latn|tarakhshaqūn}}, meaning a bitter herb.Gledhill, David (2008). The Names of Plants. Cambridge University Press. {{ISBN|9780521866453}} (hardback), {{ISBN|9780521685535}} (paperback). pp 279, 371 The Arabic term is possibly of Persian origin.{{cite dictionary |url=https://www.collinsdictionary.com/dictionary/english/taraxacum |dictionary=Collins |title=Taraxacum |access-date=2 May 2025}} Persian polymath Al-Razi used the word {{lang|ar-Latn|tarakhshaqūn}} in relation to dandelions, chicory, and endives.{{cite book |last1=Neves |first1=Liz |title=Northeast Medicinal Plants: Identify, Harvest, and Use 111 Wild Herbs for Health and Wellness |date=2 June 2020 |publisher=Timber Press |isbn=978-1-60469-913-5 |page=14 |url=https://www.google.com/books/edition/Northeast_Medicinal_Plants/femvDwAAQBAJ |language=en}} Al-Razi wrote "the {{lang|ar-Latn|tarakhshaqūn}} is like chicory, but more efficacious"; it is unclear exactly to which plant Al-Razi referred.

Dandelions contain bitter but water-soluble sesquiterpenes. The bitterness increases later in the season, after the flowers bloom, and as the leaves mature. To make dandelion greens more palatable, they can be blanched, picked young, served with other strong flavours, or some combination. In the Southern United States, they are traditionally served with a hot bacon dressing (similar to spinach salad).{{cite book |author=McGee, Harold |title=On Food and Cooking: the science and lore of the kitchen |publisher=Scribner |location=New York |year=2004 |page=320|isbn=978-0-684-80001-1 |chapter=A survey of common vegetables |chapter-url=https://books.google.com/books?id=bKVCtH4AjwgC&pg=PA320|title-link=On Food and Cooking}}{{cite web |last1=Kallas |first1=John |title=Making dandelions palatable |url=https://www.backwoodshome.com/making-dandelions-palatable/ |website=Backwoods Home Magazine |date=22 December 2015}} In Italy, the leaves are sauteed, added to soups, or added raw to salads.{{cite web |url=http://www.italianfoodforever.com/2008/05/sauted-dandelion-greens/ |title=Sautéed Dandelion Greens |work=Italian Food Forever |archive-url=https://web.archive.org/web/20120208001954/https://italianfoodforever.com/2008/05/sauted-dandelion-greens/ |date=May 29, 2008 |archive-date=8 February 2012 |last=Mele |first=Deborah}} Dandelion greens have been a part of traditional Kashmiri cuisine, Lebanese cuisine,{{cite web |last1=Bergo |first1=Alan |title=Lebanese Dandelions with Carmalized Onions |url=https://foragerchef.com/lebanese-dandelions-with-caramelized-onions-hindbeh/ |website=Forager Chef |date=27 March 2021 |access-date=16 March 2024}} Spanish cuisine, Italian cuisine, Albanian cuisine, Slovenian, Sephardic Jewish, Chinese, Greek cuisine ({{lang|el|χόρτα}}) and Korean cuisines.

The ability of dandelion seeds to travel as far as a kilometre in dry, windy and warm conditions, has been an inspiration for designing light-weight passive drones.
In 2018, researchers discovered that dandelion seeds have a separated vortex ring. This work provided evidence that dandelion seeds have fluid behavior around fluid-immersed bodies that may help understand locomotion, weight reduction and particle retention in biological and man-made structures.
