Can anyone Identify these plants?

[Tomatoking]

I have two different plants that have come up in my flower garden, both of them are now quite tall, approx. 4ft. The first picture shows one which has pink flowers and the other pictures show the other one which have no flowers. I've noticed that there are now lots more smaller plants like these coming up in other places in the garden. This is our second summer at this house and I've not noticed them before, and haven't planted any new seeds. They could be weeds or wild flowers maybe? So any suggestions? I'm puzzled!

The first one is a member of the brassica family - it is similar to hesperis matronalis but the leaves are wrong - maybe honesty?
The second one is a member of the spurge family - euphorbia.

2nd and 3rd - Caper spurge - poisonous - has seeds like capers (except toxic!)
The last is another euphotbia I suspect.

I agree with Jeanie that no 1 looks like Honesty - Lunaria.

Thanks very much to you both, I've now looked these plants up. Looks like I'll be leaving them in the garden now and not pulling them up thinking they're weeds. Am I right in saying that the Honesty plant has a lovely scent in the evening?

Hmm - I wasn't sure about the fragrance but all of the cousins are, so I would have thought Honesty would follow suit- here's a link.

Number four looks like a euphorbia too, though a different type than what is likely a caper spurge. When it flowers that will help!

Hmm, the leaves don't look right for honesty, but the flowers do. I'm with you all on the spurge and euphorbia

Hi tom. the no.2 and 3 euphorbia is reputed to keep moles away and the no. 4plant is also a euphorbia- I'd say it is characis ' Wulfienii' or martinii. All of the spurges are poisonious and irritate the skin and eyes.

they look nice dont they.

I think number 1 could be Dame's Rocket - if I could just find out how to post a pic!!!

[Jeanied]

Dames Rocket = hesperis matronalis.

I would weed the lot out - except no'4. Caper Spurge seeds are viable in the ground for a long time and you will be over run, similar story to Dames Rocket which is also invasive.

[Flummery]

There's a garden in the village with a caper spurge in. It isn't invasive - they only ever have the one.

Perhaps they're lucky!!! I moved here 10 years ago and the garden was full of it - it took me years to weed the lot out and I still occassionally get the odd seedling pop up here and there.
