When and where did you find them Archie.
They're not the ripe seeds of anything. They are an acer though
Mow the grass and get the rest filled with good leafy perennials keen. I have this one and it doesn't give me a lot of grief. It takes over on bare earth but doesn't infiltrate other plants to the extent that ground elder does.
That's what it is, Enchanter's nightshade. Just as invasive as ground elder but not quite as tall
I wouldn't look into all your plants too closely, you might find there's nothing 'safe' there.
I'd never been on a forum before when I turned up here and it seemed to be telling me I needed a user name other than my own. I use my own name everywhere else but have never changed it here. It confuses me when other people change their names
I never touch pesticides, never have. and haven't used herbicides for years.
all goes along very well here without them
It can be hard to tell if you can't poke about in them.
agree, nowhere near ripe enough to germinate. If you do get some ripe ones don't crack them open, sow them and leave outside over winter.
Hoe it off and plant something else. If it wasn't that it would be another weed, something always grows, the art of gardening is to choose what grows.
