Plant ID please
hi, could anyone ID these for me please. The tall plant I initially thought was a weed but looks too statuesque to be a weed! The pale pink in the foreground. The seedling in the pot I grew from seed but can’t remember what it is. The other two seedlings are coming up all over a new piece of lawn I’ve recently dug over to make a new border. They look like cosmos to me but I didn’t think that cosmos self seeded. Any help would be appreciated.
