Clypeola jonthlaspi, commonly known as Disk Cress or Shield Penny-Cress, is an annual herb that is native to a variety of habitats in Europe and Western Asia, including meadows, pastures, vineyards, and cultivated fields. It typically grows to a height of 0.5-1.5 feet (0.15-0.5 meters) and features small, white flowers that bloom in the spring and summer, adding a delicate touch to garden settings. The plant has a basal rosette of leaves from which stems arise, each bearing clusters of the distinctive disk-shaped fruits for which it is named.

Disk Cress is valued for its ease of growth and its ability to thrive in a range of soil types, including loam and clay. It is often used in wildflower meadows, cottage gardens, and as a filler in mixed borders due to its unassuming appearance and pollinator-friendly flowers. While it prefers full sun, it can tolerate light shade and requires medium amounts of water with good drainage. Disk Cress is not commonly known for any significant problems or diseases, making it a low-maintenance choice for gardeners. However, its ability to self-seed may require management to prevent unwanted spread.CC BY-SA 4.0
