It’s winter.  Mostly.  The plants are dormant but there’s no snow to brighten the ground.  With temperatures in the 40’s and overcast skies the landscape is brown in Pittsburgh.

But what is this?  A spot of green on this last day of 2011.  What plants are braving the cold in Schenley Park?

Two alien invasives:

Goutweed …

… and Garlic mustard.

Perhaps it’s not wintry enough for them.
