Weeds with black seed pods

Weeds with black seed pods

Shallow, taprooted, low, trailing winte r annual or short-lived perennial forb, with prostrate or ascending stems up to 30 inches long; where thick stands develop, stems may become erect, obtaining heights of 18 to 24 inches; 4-angled stems are typically purple at the base, hairless or more rarely with some short hairs, although older stems become less hairy; they branch occasionally.

Leaves: Alternate, compound leaves are trifoliate (cloverlike); younger leaves, toward the stems tips, have short hairy petioles; older leaves have longer petioles (up to 1-3/16 inches long); paired stipules at petiole base are lanceolate to ovate and variable in size; leaflets are up to 9/16 inch long and about half as wide; medium to dark green, wedge shaped or obovate, hairy or nearly hairless, finely toothed with prominent veins.

Flowers: Flowers February to December; 2 to 8 small, bright yellow flowers are borne in clusters about 1/2 to 3/4 inch long; each flower is about 1/8 inch long; when fully open, it has a pealike floral structure with an upper standard and lower keel.

Fruit: Fruit is a spirally twisted, thick-walled pod; each pod is black, about 1/8 inch long and contains a single dark seed that is somewhat flattened and kidney shaped, less than 1/8 inch long.

Habitat

Cultivated and disturbed or degraded sites in meadows, grassland, woodland, and forest communities, and roadsides within elevations that generally range from 4,000 to 8,000 feet.

Propagation/Phenology

Reproduces by seed; one well-developed, vigorous, plant may produce more than 1,000 seeds.

Native to Eurasia and Africa; black medick easily spreads and can form large colonies and where it is allowed to grow undisturbed, black medick may displace native species. Prior to fruiting, black medic could be confused with burclover. This species generally occurs as a weed in wildland areas of the Southwestern Region rather than as an invasive plant.

Weed with black pods

Hi all! I’m a newbie gardener who has inherited a jungle of a garden in my recent house move. Please could anyone help me identify a weed with black pods which has spread rapidly in my front garden? The pods are shooting seeds across the plant beds so it’s growing quickly. I am currently trying to get rid of it but worried that it will continue to come back as I cannot identify a root. Any help will be greatly appreciated!

Lots of plants have black pods. Can you do a photo, or a fuller description, shape of leaves, colour of flowers, height, any else about it

I have photos but not sure how to upload it to this forum? It has long arching stalks that are tangled between all the other plants and small (elongated oval) leaves.
