Heart-podded hoary cress (Lepidium draba sub. Draba)
Description: Plants grow up to around 2'-3' tall, have grey/green leaves, and are usually covered in short hairs but can be hairless.
Life Cycle: Perennial forb
Habitat: Disturbed sites, pastures, roadsides, along riverbanks and other waterways
Leaves: Alternate, blue-green leaves, 1.5"-3" long, with fine hairs. Lower leaves have stalks while upper leaves are without stalks and are heart-shaped.
Flower: Clusters of flat-topped white flowers
Fruit: Seed pods are somewhat heart-shaped, dark brown, and hairless
Root: Rhizomatous
The problem is…heart-podded hoary cress is highly competitive and displaces native vegetation. It can also reduce the value of high-price wheat lands. One mature plant produces 1,200 to 4,800 seeds
