About Hoary cress
Lepidium draba, commonly known as hoary cress, is a perennial herbaceous plant belonging to the Brassicaceae family. It is characterized by its dense clusters of small white flowers blooming in spring, and grayish-green foliage. This robust plant can be ornamental in wild-style gardens or along roadsides, but should be managed with caution due to its invasive potential.
Native range
Europe and Western Asia
Care tips
Hoary cress thrives in full sun to partial shade and is highly tolerant of various soil types, even poor or disturbed ones, as long as they are well-draining. Once established, it is extremely drought-tolerant and does not require frequent watering. It is crucial to prevent its uncontrolled spread, as it can quickly become an invasive weed; early removal of flowers to prevent seed formation is recommended.
