Cultivation / Plant breeding

Taraxacum officinale F.H. Wigg

The dandelion is a common colonizer of disturbed habitats, both from wind blown seeds and seed germination from the seedbank. The seeds remain viable in the seedbank for many years, with one study showing germination after nine years. This species is a somewhat prolific seed producer, with 54 to 172 seeds produced per head, and a single plant can produce more than 5,000 seeds a year. It is estimated that more than 97,000,000 seeds/ hectare could be produced yearly by a dense stand of dandelions. When released, the seeds can be spread by the wind up to several hundred meters from their source. The seeds are also a common contaminant in crop and forage seeds. The plants are adaptable to most soils and the seeds are not dependent on cold temperatures before they will germinate but they need to be within the top 2.5 cm of soil [ 1 ].
The plant tolerates low temperatures (-8°C), can tolerate occasional snow cover for up to a couple of weeks per year.
