    Hairy Bittercress is one of our first spring flowers, often popping up in late winter. A little later in the spring, when daffodils are in bloom, it has developed taller stalks and is starting to grow its linear seedpods.

    This lush patch was growing in Bird Park, Mount Lebanon.

    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.
