100 More Species #47: Evening primrose

[urbpan]

Evening primrose Oenothera biennis

At the back of our yard, we allow the weeds to grow. In one corner they grow very tall indeed. When I featured this plant as 365 urban species #233 I said that it might grow as tall as five feet. The row in the back of our yard includes specimens that are easily seven feet tall.

Evening primrose blooms in the evening, and stays open until late the next morning. This allows it to be pollinated by day-flying and nocturnal insects both.

They look a bit imposing. Do they make tap-tap-tap noises by any chance?

(I see you also have some healthy poison ivy back there too)

No we're pretty adamant about removing poison ivy when it pops up. There's some black raspberry brambles there showing leaves of three in that first photo.
