Heart-podded hoary cress (Lepidium draba sub. Draba)

Description: Plants grow up to around 2-3 feet tall and are usually covered in short hairs but can be hairless

Life Cycle: Perennial

Habitat: Disturbed sites, pastures, roadsides, along riverbanks and other waterways

Flower: Clusters of flat-topped white flowers

Fruit: Seed pods are somewhat heart-shaped, dark brown, and hairless

Leaves: Alternate, blue-green leaves. Lower leaves have stalks while upper leaves are without stalks and have two lobes clasping the stem

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
