(Pimpinella saxifraga )
This species is Introduced in the United States
Origin
Native to the British Isles, temperate Europe, and Western Asia.
Appearance
Pimpinella saxifraga is an erect herbaceous perennial growing up to about 1.5-3′ (0.5-0.9 m) tall with a long taproot. The stem is slender and solid. This plant looks very much like Daucus carota, wild carrot.
Foliage
P. saxifraga has alternate compound leaves. The basal leaf blades are pinnate (divided) to bipinnate with toothed oval leaflets. The stem leaves are bipinnate (twice divided) with narrow leaflets.
Flowers
The small white flowers have 5 petals. They are held on very short styles in a terminal compound umbel.
Fruit
The small flat ovate fruits are schizocarps from 0.12-0.16" (2-3 mm) long. They are very slightly ribbed.
Ecological Threat
P. saxifraga can tolerate a wide variety of growing conditions. It prefers calcareous grasslands but can also be found on acidic sands.
