Fumaria muralis is a delicate annual plant that flowers in spring. It is most easily distinguished by its flowers, which have pink petals with dark red or purple tips. There are about twelve flowers per inflorescence. The stems are initially erect then become sprawling or climbing. They are weak and many-branched, up to 1000 mm (39.4 in) long, and hairless.

The leaves are green or glaucous-green, polyternate, 2- to 4-pinnatisect with narrowly elliptic or oblong last order segments. The first leaves grow singly and are 7–15 mm (0.3-0.6 in) long with a stalk 7–15 mm (0.3-0.6 in), and have three hairless leaflets. Later leaves become more compound and lobed. Mature leaves are three times deeply lobed with three or more leaflets, 3–15 mm (0.1-0.6 in) long. Alternate leaves form a rosette. Leaf segments are egg-shaped to triangular and usually three-lobed and hairless. The blade is gray-green to blue-green, flat, and up to 80 mm long x 40 mm wide (3.2 x 1.6 in). The flowers are grouped in axillary racemes. Pedicels are subtended by a linear bract and are straight or recurved outwards at fruitification. The corolla is pink, sometimes lightly so, and dark red or purple at the apex; it is 9–12 mm (0.35-0.47 in) in length. It is made up of four petals of which the outer upper and lower ones are free while the two inner ones are fused into a tube closed at the apex. …

F. muralis is native to temperate and Mediterranean regions of western Europe and western North Africa. In its native range, it is found in Macaronesia, Portugal, France, Belgium, Germany, United Kingdom, Ireland, and Norway. Outside its native range it is present in Spain, Netherlands, Denmark, Japan, New Zealand, Australia, South Africa and the United States.

F. muralis prefers to grow in open, bare patches and is considered a weed of pastures, roadsides, gardens, footpaths, coastal shrub lands and disturbed areas.
