Sneaky Common Chickweed is Going to Seed boggs.47 Tue, 04/18/2017 - 08:41
Common Chickweed (Stellaria media) is a European winter annual that is now found world-wide. Winter annuals are sneaky weeds. They produce seeds in the spring then plants fade away prior to the summer season; out of sight, out of mind. The seeds dodge spring applied preemergent herbicide bullets because they do not germinate until the fall. The resulting plants grow below our radar throughout the fall, winter, and early spring when we pay little attention to what's going on in our lawns and landscapes.

Cressleaf Groundsel: A Grown-up "Weed" boggs.47 Mon, 04/17/2017 - 12:08
I've watched Cressleaf Groundsel (Packera glabella; syn. Senecio glabellus) for years popping-up in landscapes and farm fields. However, I never truly appreciated the canary yellow display provided by this winter annual. Indeed, I've placed all of my past BYGL reports on this native plant under the header, "Weed of the Week."
