Verbena bonariensis

Great plant. I put one in the greenhouse over the winter and the other I left in the garden. The greenhouse one is flowering but the other one is looking good.

Seed everywhere here, in the path, in the drive and of course in the borders, but useful.

I like how you can plant them at the front of the border and get away with it.

I call that sort of plant airy.

Airy is a good description :-)

I agree Siris..... everywhere! but so useful!
