Common Dandelion🌼
Taraxacum officinale
セイヨウタンポポ
A perennial herb that blooms yellow flowers from spring to early summer. One of the most commonly seen plants along roadsides and in parks. Originally from Europe, this introduced species can be distinguished from native Japanese dandelions by its reflexed (recurved) outer involucral bracts.
Identification Points
- ✓Outer involucral bracts are reflexed (native dandelions have erect bracts)
- ✓Leaves form a basal rosette and are deeply lobed
- ✓Flowers are bright yellow; seeds form a spherical pappus that disperses in the wind
