| Description: |
Plant with cross-cut saw shaped leaves in basilar leaf rosettes and a straight, fleshy root; all parts with milky sap; stalk 5 - 40 cm high, unbranched, tubular, hollow and with only one capitulum; this is 3 -5 cm wide and consists only of yellow ligulate ray flowers; fruit with a stem on which a tuft of hair is situated (pappus) so as to be dispersed by the wind (anemochory) (headword: parachute, dandelion-clock); perennial; entomogamous (bee pasture); flowering season: III - VII; medicinal plant and vegetable;

| Occurence: |
Common, on fertile meadows and pastures, cultivated fields, dunes and ruderal places;
|
| Related species: |
Taraxacum is an extraordinarily diverse genus and still in the process of developing new types. So far approx. 240 subspecies have been described, which populate nearly every biotope from the plane up into Alpine regions. The flowering season reaches from March to September.
|
| Allergy trigger: |
Pollen, approx. 35 µm;
|
| Invasions path: |
Inhalative (May - August); ingestive (mixed honeys, dandelion honey);
|
| Synonyms: |
About 140 subspecies are summerized as the group T.-officinale. Classificating literature utilizes very different systems and names for groups and species.
|
| Allergology: |
Because of the relativly small amounts of pollen it is not important as an inhalative allergen; however, the strong cross-allergenicity to other composites often leads to a positive test result.
