Solved 2 plants to identify please

We are renovating and the garden was derelict for 20yrs. Any ideas what either plant is please? I don't mean the nettles and alkanet, but the taller plant in that pic and the other in the pot with tassels.

 

The ‘grassy’ one with the tassels is Carex pendula … a tenacious invasive PITA. I would get rid of it and keep my eyes open for seedlings popping up anywhere in your garden.

The statuesque one behind the alkanet is Euphorbia lathyris aka Caper spurge/mole spurge. They self-seed and pop up especially when neglected soil has been disturbed. They can be regarded as a nuisance but I quite like them. They’re nothing like as tenacious as the carex and can be removed by pulling up…. BUT wear long sleeves and gloves as the milky latex-like sap can burn if it gets on your skin and is exposed to bright sunlight. I know ‘cos I got some on my leg when I was a child and I remember the painful red weals … and definitely don’t let it get in your eyes. However the same is true of all euphorbias and it’s not stopped them being very popular garden plants.

 

Thank you so much Dove from Above
