I just moved into a house and discovered a plant/grass on the shady side of
the house. It resembles grass only thicker blades and the root is small
bulb shape. It grows in clumps.Once I started watering it, grew taller with
no flowering or other growth.
I live in Eastern Montana
Thanks in advance for any information.

Sounds like nut sedge. Yikes. Check out the nut grass thread above. I
