Sorry about the small photo, I'm consistently getting an unknown upload error with photomuppet this morning...

There are some narrower leaves which don't belong to this plant, the broader leaves to the right of the picture do. I had a couple of thoughts as to what it might be, but I don't believe myself. Anybody else got any thoughts?

Is it not Evening Primrose?

Seems to pop up eveywhere.

As for plant or weed - your choice!

I think E P too

Ooh! No I wouldn't call that a weed. Now, I wonder where it came from to get in my garden? Its not a plant I'm familiar with seeing around here.

[DD.]

It's appeared from nowhere both on my plot and in our front garden.

I've let it be.

I've seen birds eating the seed so they probably spread them. Mine "arrived" a couple of years ago and although they spread they're no bother.
Lovely in the evening when their yellow flowers sort of glow white.

Where they have "landed" is an area which does get weekiller applied. I wonder if they relocate successfully?
