Common ramping-fumitory

Fumaria muralis, the common ramping-fumitory, is a sprawling annual herb in the family Papaveraceae (subfamily Fumarioideae) native to western and southern Europe and widely naturalized in temperate regions including the British Isles, North America, Australia, and New Zealand. Plants are scrambling or weakly climbing, with weak slender stems 20-80 cm long and a glabrous, often somewhat glaucous overall appearance. Leaves are alternate, 2-4 times pinnately compound into flat, narrow, oblong-lanceolate ultimate segments 5-10 mm long, giving the foliage a delicate ferny texture. The inflorescence is a lax raceme of 12-25 flowers borne opposite the leaves; each flower is pink to purplish with a dark crimson or blackish tip, 9-12 mm long, spurred at the base and bilaterally symmetrical, with the upper petal forming a saccate spur. Flowering occurs from spring through autumn. The fruit is a nearly globular one-seeded nutlet 2-2.5 mm across with a slightly rugose surface. The species inhabits arable fields, gardens, hedge banks, waste ground, and disturbed soils at low elevations.
