Overview

Bittercress (Cardamine pennsylvanica) is a biennial or perennial forb that thrives in moist to wet conditions across various regions including Alabama, Alaska, Alberta, Arkansas, and British Columbia. This plant can be found growing in light to partial shade with soil types ranging from sandy to clay, thriving best in a pH level between 4.8 and 6.8. Bittercress reaches a height of about 0.6 meters and is adaptable to hardiness zones 4-8, making it a versatile addition to gardens or natural landscapes. The edible leaves of bittercress are particularly useful as a condiment, adding a piquant flavor to salads and other dishes. This plant is known for its ornamental value, with white flowers that contribute to the aesthetic appeal of any garden setting. Bittercress grows well in full to partial sun and prefers moist conditions, making it suitable for areas where water retention is good. While bittercress can be propagated via seed sowing directly into the garden bed or by dividing established plants, care should be taken when handling this plant as its leaves contain mustard oils that may cause a burning sensation if ingested in large quantities.
