If you're not a football addict, or can squeeze it in around game time, Baltimore's merging watershed groups are offering residents a chance Sunday to help restore the harbor by buyng - and planting - native trees, shrubs and plants.

The Baltimore Water Alliance, the working name the groups have adopted for now, is having a sale at the Herring Run Nursery, 6131 Hillen Road, 21239, from noon to 4 p.m. Sunday (9/26).  There'll be more than 100 different native trees, shrubs and plants to choose from, plus some perennials.  If you can't make it this weekend, there'll also be sales Oct. 9 and 24.

Proceeds help underwrite the operations of the new alliance, which brings together the Herring Run, Jones Falls and Gwynns Falls watershed associations, plus the Baltimore Harbor Waterkeeper.  Coupons worth $10 to $25 discounts on trees available.  For information on stock and coupons, go here.
