Solved Anyone identify these 3 different plants/weeds?

Hi all,
Could anyone help identify these 3 plants (or weeds maybe) that have appeared over the last week in our rather “wild” border at the back of the garden that I am currently tidying up and getting ready to plant out some seedlings.
Have these been planted intentionally by the previous owners who were big gardeners, or are they just “wild” and want taking out, two haven’t flowered yet, but thought someone may be able to identify them?
Cheers.

 

I think 1 and 2 re both Hesperis matronalis (Sweet Rocket, Dame’s Rocket) … gives a beautiful scent to the air on a warm summer evening, and great tie nightflying pollinators. A short-lived perennial very popular in cottage gardens. Thankfully good at self-seeding about the place. There’s a white form as well as the lilac one.

Not sure yet about the third.

 

I think they're all Sweet Rocket

 

Thanks for the replies.
Are they keepers then?
Should they be cut back to ground level when they have finished flowering?
Thanks.

 

Forgot to add……
These will have been planted intentionally in the past?

 

nice smell, nice plants

 

Yes they’re garden plants … I rate them
highly for their attractiveness, their perfume and their value to insects. i don’t cut them back until the end of winter as they are good self-seeders if left alone to get on with it.
They can be a bit tricky to raise from seed in seed trays etc so I just leave them to do it themselves.

 

They'd be keepers for me. Easy enough to remove if they'r ein a place you don't want them.
They'll probably just have arrived from a garden or verge nearby, although some people do sow seed and plant them.

 

I think sweet rocket (Hesperis) is a biennial, but I've never grown it so maybe someone else will confirm, or otherwise!.
With biennials you let the plants set seed, which will grow this year and flower next year, like honesty, foxgloves, forget-me-nots etc. If you cut back the old flowering stems after the seed has been shed, the parent plants might survive another year (for me, foxgloves sometimes do, but honesty and forget-me-nots don't).

 

I find that sometimes they are biennial, others they are short lived perennials, so if you like them, let them seed around.
