Solved PlantID please - what might that be

I can find lots of them in one corner of the garden where no plant with such leaves is. Around is only one plant, Hesperis Matronalis, that I haven’t seen what it looks like from seeds. Since there are so many of them, and it doesn’t look like a Cyrinthe, I wonder what they are. I have potted 4 on.
The stem is here around 8cm long.





Many thanks in advance.

 

They look like sunflower seeds / seedlings to me @simone_in_wiltshire . I’ve just plucked two from our borders, presents from the birds.

 

Thanks a lot @Songbird. I have seen sunflowers in the close neighbourhood.
It’s so weird that they are just inside a 2x2 meter radius but in particular in the only crowded area with Cosmos, Lavender, Gaura, Cornflower on one side and Echinacea, Helenium and Perowskia on the other side. I was wondering if the landscape bark for the paths had them. I have pulled out probably 40 plants so far.
I will see how the potted on develop.

 

Lots of plants have seed leaves that look completely different from their true leaves. Good idea to grow a few on and see what they turn into.

 

It looks like my cerinthe - honeywort. This is one of my self sets. Mine is bigger than yours but you can still see the seed leaves at the bottom.

 

That’s what came first in my mind but my one don’t have the Cerinthe typical white/light “spots”.

 

I would say cerinthe as well. Not all of my seedlings have white spots .

 

I would wait, almost impossible to tell before the true leaves appear.

 

I will patiently wait. I did have cerinthe in the raised bed which that naughty fox attacked. Maybe he took some seeds

 

Borage also looks like that when it emerges. It's easier to ID as the foliage becomes hairy/bristly quite quickly.

 

Update: I found a seedling that had already true leaves and it’s a Cerinthe

 

Good news @simone_in_wiltshire . Having such similar leaves to other plants it’s difficult to be absolutely sure until those true leaves come through. We haven’t grown Cerinthes since moving house, I must get some seeds for next year as I really fancy trying to grow them here now.

 

@Songbird I'm careful what grows in my garden since I had to dig up everything because of creeping cinquefoil.
As you can see in my case, once you planted a Cerinthe, no need to buy new seeds

 

I shall look forward to growing them @simone_in_wiltshire because if they self seed as they did at old house, I shall be happy to let them have full reign over some parts of the garden. We have been trying new things in the garden over the past year as we have some very hot, dry spots where plants are wilting badly in the weather changes. If they make it there, well, they can have as long a life as they want

 

@Songbird They definitely deal good with dry conditions. I had my one in the raised bed and grown from a seedling found in November. It grew happily over winter and it was the first in April that flowered much to the joy of first white tail bees. It stayed flowering despite getting no water at all up to June until that awful fox youngster savaged both raised beds. The second seedling found in June never developed due to the lack of water in the raised bed.
