What to Eat
Edible parts: Leaves, Stems, Seeds - spice
Young leaves and shoots can be eaten raw in salads or cooked as a potherb. Note that young leaves have been reported to contain hydrogen cyanide; in small quantities this substance is relatively harmless and has even been suggested to have health benefits, but caution is advised. The pungent leaves are also used as a seasoning. Seeds serve as a condiment and pepper substitute. The leaves, flowers, and seeds are all edible when cooked. Raw, the flavour is intensely spicy, mustardy, and sharp — far too aggressive for most salads — and the hoary texture of raw leaves is off-putting. Cooking improves all parts significantly, softening fibres, reducing bitterness, and taming the glucosinolate heat. Flower clusters can be used similarly to broccoli florets when briefly cooked, though their flavour is less refined. Seeds are spicy and benefit from toasting or boiling. The plant rates highly as a survival or bulk-foraging species due to its abundance and reliability, despite moderate culinary quality. Fresh leaves taste spicy, acrid, and cabbage-like with strong wild-mustard intensity. The felt-like surface hairs create a dry mouthfeel when raw but soften with heat. Boiled leaves become mild and palatable. Fresh flowers are the mildest component, with slight sweetness from nectar traces; unopened clusters can be steamed, boiled, or added to mixed greens. Seeds are hot and mustard-like; roasting brings out nuttiness and reduces harshness. Thorough washing is essential before cooking. Rosettes emerge in early spring and flowering runs from May through August depending on climate and elevation. Leaves are most palatable in spring through early summer, becoming tougher as plants mature. Seeds can be collected by tapping mature pods into a container, then dried and winnowed before toasting or grinding.

How to Identify
A cabbage family herb. It keeps growing from year to year. It has a stout taproot. It also has a tough, woody, much-branched root system. New shoots can develop from these side roots. The plant grows to 90 cm high. The stem is usually unbranched except just near the top. The leaves are oblong or oval and covered with flattened hairs. The leaves do not have stalks and clasp the stem. The flowers are in a flat topped panicle. The petals are white. The fruit are heart shaped. The fruit separates from the plant as a single seeded nutlet.

How to Grow
Plants are grown by seed.
Propagation: Sow seed in situ in spring. Division can be done in spring. There is little need to actively encourage this plant, as it is a rapidly spreading weed in Britain.
Medicinal Uses
The plant is antiscorbutic. The seeds have been used as a remedy for flatulence and fish poisoning — the latter reference is assumed to mean food poisoning from suspect fish.
Other Uses
Flowers are highly attractive to insect pollinators, particularly small bees, syrphid flies, and other generalist foraging insects. Rhizomatous mats can exclude native forbs and grasses, reducing biodiversity and altering soil dynamics. Seeds may be eaten opportunistically by small birds or rodents. The plant's glucosinolate chemistry provides some resistance to herbivory.
Wikipedia
Cardaria draba is a perennial reaching 50 cm tall, hardy to UK zone 6. It flowers May–June and grows in semi-shade to full sun across sandy, loamy, and clay soils with mildly acid to basic pH, preferring moist conditions. Hermaphroditic flowers are pollinated by bees and other insects; the plant is self-fertile.
Notes
Declared noxious weed in Victoria. It does not contain oxalic acid in samples in Spain.
