Description
 
 

Wild radish is a 12 to 24 tall, erect, annual forb rising from a small, thick taproot. Initially, there is a rosette of basal leaves. Later, a stem is produced.

The stems are branched in the upper portion and usually covered with firm, stiff hairs.

The basal leaves are up to 8 long and 2 wide. They are oblong, two to four times longer than wide, to inversely egg-shaped, attached to the leaf stalk at the narrow end. They are divided into 5 to 15 oblong lobes with the lower lobes very small, the upper getting progressively larger, the largest lobe at the end. The upper leaves are alternate, smaller, often unlobed, and attached to the stem on short leaf stalks. All leaves are covered with short, stiff hairs.

The inflorescence is a cluster of stalked flowers at the end of each stem and branch.

The flower is ½ to ¾ in diameter on ¼ to ¾ long flower stalks. The petals are 4-parted, yellow, and prominently veined, eventually turning to white. They narrow abruptly near the base to a long claw. The flower stalks become erect when the flower matures.

The flower is replaced by a single fruit, a 1-celled pod, ¾ to 1¼ long with a to 1 long beak-like tip. It stands erect on the already erect flower stalk. It has two segments. The lower segment is short and does not bear seeds. The upper segment contains 4 to 10 seeds in a single row. It is thick and cylindrical when fresh, prominently ribbed and dented between the seeds when dry. To disperse its seeds it breaks into fragments between the 1-seeded segments.

About

Published on Dec 12, 2013

A parody of the Gotye hit "Somebody I used to know" by agronomic consultant Bill Long, who farms on the Yorke Peninsula of South Australia as well as consults to a number of farmers in the region. This is a farmer's lament on attempts to control wild radish resulting in the loss of chemical options to the point where only radical options are available. Truly reflects the consequences of farming systems becoming reliant on herbicides for weed control.

apparently this can cross polinate with charlock mustard/european wild mustard and give you yet another kind of plant.
