parsley
Petroselinum crispum (Mill.) Fuss
Parsley changes markedly between its leafy first season and its flowering second one. Young plants form a compact rosette, while older plants raise branching stems above the foliage. Though commonly grown as an annual herb, this two-year cycle allows it to flower, set seed and sometimes establish a new generation nearby. NC State Extension: Petroselinum crispum

Recognizing the plant
The dark green leaves are divided into smaller segments and may be flat or tightly curled, depending on the cultivated form. Basal leaves have relatively long stalks; leaves higher on the flowering stem become smaller and more narrowly divided. The stems are slender and hollow. Tiny, five-petaled greenish-yellow flowers are arranged in compound umbels, with smaller flower clusters carried on the rays of a larger umbrella-like structure. The small gray-brown fruits are ridged. Flora of China: Petroselinum crispumNC State Extension: Petroselinum crispum
