This patch of European Common Reed was found on the side of the road between a parking lot and an area that appears to be a leach bed for a septic system.

Supporting Evidence

The measuring tape tucked into the reeds is set at 6' and demonstrates the reeds are much taller than 6'.

The pale green leaves are wide and arranged alternately. The stems are round.

Yes, that leach bed is probably feeding the reeds as you suggested!

I think the phrag mayb be pretty much as large as it will get in that one spot. The road is on one side and mowed areas surround it. Maybe it has a path of escape going away from the road if that area isn't mowed very much. I'm sure seeds will spread and find some more areas to start up.

Great idea to bring that measuring tape with you! Nice piece of evidence.

Sounds like that phrag might be capitalizing on the extra nutrients from the leaching field....

It'd be interesting to measure the area the stand is taking up each year to see its expansion. My prediction is that it'll increase by 6+ feet or more (!!) each growing season as the stalks lay down and deposit seeds. Hmm. What's your prediction?
