Is that Lobelia?

Simone_in_Wiltshire

I have grown Lobelia from seeds, and all the time, they looked like they didn't want to go further in these cold days.
This morning, I discovered that something has happened over night. As you can see in the image, some parts of the plant look like they got too much frost. This was the stage until yesterday.
Since I had to take out the entire lawn due to a creeping cinquefoil invasion, I'm very careful with what comes up in that part.
Can you tell me if that is now the growing from the Lobelia?
I checked with the internet but I can see only blossoms but not the actual green.
Unfortunately, I can't remember the exact type of Lobelia. It was just an old seed bag that needed to be planted, in case there are many sorts of Lobelia around.
Many thanks in advance.

Many thanks, Hostafan1. 

Job done. 

I hope I come away with that. No more invasive plants, please.

I don’t know any lobelia seedlings that look like that.

Thanks, Lyn. That's what made me suspicious. I'm by no means the Lobelia expert, but I said to myself, "this is not right". It was not there on Thursday, that means it grows extremely fast.
I eliminated it immediately and checked all other plants and parts of the garden. I will keep an eye on this.

Yes, you have willowherb growing amongst your seedlings. The seedlings themselves look like perennial lobelia, not the annual (bedding) kind.

Hi Rachel, it’s just that one Lobelia which was affected. Everything else looks fine. I spend a lot of time every day looking around and can say that each single tiny green is taken out of the the garden. This is also required to eliminate any creeping cinquefoil attempt. That’s why I filled the entire space with plants grown from seeds so that I can take out any cinquefoil in case I missed one. 

Either that willow herb was amongst the Lobelia seeds or came with the farm manure. 

But I’m on a permanent watch.
