Adding early spring color to the woodland garden, Cardamine concatenata (Cutleaf Toothwort) is a rhizomatous perennial boasting charming clusters of small, four-petaled, white flowers, sometimes tinged with pink, in early to late spring. The flowers sit atop an erect stem clad with a whorl of finely divided, toothed leaves. Cutleaf Toothwort is a spring ephemeral, emerging before the leaves leaf out on deciduous trees and going dormant by early summer. Quite resilient, Cardamine concatenata spreads slowly by running rhizomes to form a lovely carpet over time. It is perfectly suited to woodland gardens or any shady areas where it can be allowed to naturalize.

  • Grows up to 6-12 in. tall and wide (15-30 cm). 
  • Easily grown in humusy, organically-rich, moist, well-drained soils in part shade. Cover with a light layer of leaves in winter.
  • A welcomed addition to shaded gardens, rock gardens, naturalized areas, wild gardens or woodland gardens. Perfect for mixed borders and the front of perennial beds.
  • Cardamine concatenata combines well with other woodland wildflowers as well as ferns, hosta, to provide early season interest before the ferns and hostas emerge. Those plants will then cover up the foliage in early summer when Cardamine concatenata goes dormant.
  • Generally pest and disease free.
  • Propagate by seed or division. Seeds should be sown immediately after collection. Expect the seedlings to bloom in 3-4 years. Division should take place when the plant is dormant.
  • Native to eastern and central North America.
