Pachyphragma macrophyllum, commonly known as Caucasian Penny-Cress, is a perennial herb that is semi-evergreen to deciduous depending on the climate. It is native to the understory of deciduous forests in the Caucasus region and parts of Turkey. This plant typically grows to a height and width of approximately 2 feet (0.6 meters), forming a low, mounding clump. Pachyphragma macrophyllum is characterized by its large, heart-shaped leaves and clusters of small, four-petaled white flowers that bloom in early spring, providing an early source of nectar for pollinators.

Caucasian Penny-Cress is valued for its early spring flowers and its lush foliage, which can remain attractive throughout the growing season if moisture is adequate. It is often used in woodland gardens, shaded borders, and as ground cover under larger plants. It prefers part shade to full shade and requires medium amounts of water, thriving in soils with medium drainage. While it is not commonly afflicted by serious pests or diseases, it can suffer from root rot in overly wet conditions. Gardeners should be aware that in some regions, it can self-seed and become somewhat invasive if not managed properly.CC BY-SA 4.0
