Please identify. .....

Hi
I'm sending out an S O S hoping one of you clever kind hearted experienced gardeners can identify a flowering plant for ne....
It appeared out of the blue in my garden this summer,  one isolated small seedling that has grown into a tall inspiring blue headed flowering plant that is made up of a spire of tiny blue fower heads.
Please refer to photos I managed to gain coming towards the end of it's flowering time, it's had a long floweing period and the bees love it.
So I can grow more come next year I am desperate to know the identity of the plant so I can get more seed.  I have managed to harvest a few seeds from the plant but alas it dispersed most of it's seed whilst my back was turned, typical.
Please please some knowledgeable experienced kind hearted  gardener out there will be able to help identify this mystery plant for me, I'd be so humble and grateful for any help or assistsnce.
Until then I wish you all an autum full of inspiring happy gardening and that the weather stays dry warm and fine for a considerable time to come.....enjoy.....Thank you all who's taken the time to read this, so very kind and thoughtful. ....
You all take care now and look after yourselves....ooh plant with flowering spike reaches approximately 90cm...

Purple toadflax, I guess... There are lots of linarias on the market, some quite shorter, if you wish. This is the 'native' one...

Your plant is perennial BWS so will be back next year.  The seeds that have dispersed already you might well see coming up in the stones nearby and between the slabs so you could keep an eye out for them and move somewhere more suitable if you want more plants.

Yours is a lovely deep purple version mine are paler, possibly cross bred with the pink version. I don't believe linaria purpurea is one of the UK native toadfaxes but I could be mistaken.

It seeds happily  round my garden(trouble is I have to.evital it from my pots) is as tough as old boots and is great for problem  patches especially  dry soil.

Black Widow Spider

Thanks tessagardenbarmy that's great news to hear.......the soil is really poor and dry where I am and to hear that it is tough as old boots and seeds freely and readily is even more of a bonus and a delight to know especially as I have a whole load of problem areas........thanks for that gem of information, here's looking forward to a garden full of toadflax......thanks and take care now
