Black Sea Cardamine

One of our favorite woodland spring ephemerals has to the be the Black Sea cardamine, which has been simply glorious for several weeks in the woodland garden. Below is a photo of our patch, taken today. This amazing perennial doesn’t make an appearance above ground until early February, but soon after its emergence, it’s in full flower. Cardamine quinquefolia is a slow spreader, so put it in an area, where it’s free to move, since it will form a 6″ tall x 3′ wide patch in 4 years.

As a spring ephemeral, it will go completely dormant in May, resting during the hot summer months. We like to use later emerging plants throughout the patch, which emerge as the cardamine is going dormant. Hardiness zone 6a to 8b.

  1. What later emerging plants would you recommend with Cardamine? We are a few miles from Juniper Garden (7b).
