Nodding Toothwort flowers in the rain along the Trillium Trail in Fox Chapel.

For a description, see the Cardamine concatenata reference page.

Broadleaf Toothworts come out a little later than their cousins the Cut-Leaf Toothworts (Cardamine concatenata). The flowers are similar, but these are easily distinguished by their pair of broad three-parted leaves.
For a description of the species, see the Cardamine diphylla reference page.

A flavorful vegetable that came to our country because of its utility and found it liked its new home, Garlic Mustard can be a nuisance in the spring woods. It also grows in urban yards, as it did here in Beechview, where these pictures were taken April 16.

Blooming in Bird Park, Mount Lebanon. For a full description, see Cardamine concatenata in the Flora Pittsburghensis reference site.




Groundhog or no groundhog, we are having an early spring. Hairy Bittercress is one of the first wildflowers to bloom, and it is all over the place now. Here we see the basal rosette of leaves that is prominent early in the season; later the flowering stems will be longer and leafier.
