Taraxacum officinale Dandelion (1 Page of 5) The Taraxacum officinale plant species is found in Britain. It is a member of the Compositae family. Common gardeners may know the plant as Dandelion. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Taraxacum officinale Common Name: Dandelion Family: Compositae Author: Weber. Known Hazards: This plant has been mentioned in various books on poisonous plants but any possible toxins will be of very low concentration and toxicity[10].
There are reports that some people have suffered dermatitis as a result of touching the plant, this is probably caused by the latex in the leaves and stems[222]. Mature Height: 0.45 Mature Width: 0.3 Habitat: A very common weed of grassland and cultivated ground[17].
Cultivation Notes: A very easily grown plant, it succeeds in most soils[1], though it prefers a well-drained humus-rich neutral to alkaline soil in full sun or light shade[37, 238].
A very hardy plant, tolerating temperatures down to at least -29°c[238].
The dandelion is a common weed of lawns and grassy places. Though it has a bitter flavour, the plant is often cultivated as a salad crop and as a medicinal plant, especially in parts of Europe. There are some named varieties with larger, more tender and less bitter leaves[183]. Dandelions can provide edible leaves all year round, especially if they are given a small amount of protection in the winter[K].
A valuable bee plant and an important food plant for the caterpillars of many butterfly and moth species[4, 24, 30, 54], it grows well in a spring meadow[24].
A deep rooting plant, it has roots up to 1 metre long and brings up nutrients from lower levels of the soil[201]. An excellent plant to grow in lawns, if the lawn is cut no more than fortnightly then the dandelions will provide a good quantity of edible leaves[K]. Grows well with alfalfa[18, 201]. Another report says that it inhibits the growth of nearby plants[54]. This is probably a reference to the fact that the plant gives off ethylene gas, this gas is a hormone that promotes the premature ripening of fruits and also induces the premature fruiting of plants, thereby stunting their growth[14, 18].
T. officinale is not a valid name for this species, but no valid name has as yet been ascribed to it[200]. This is actually an aggregate species of many hundreds of slightly differing species. Most seed production is apomictic which means that plants produce seed non-sexually and all seedlings are clones of the parent, thus small differences are maintained.
