Unknown but pretty "weeds"

its purple toadflax, the pink is a colour variant. Linaria purpurea. they are also available in garden centres and a pink version is called Cannon Went.

I have a pale pink one that spreads through the garden, I leave some because it's pretty but it can be a nuisance sometimes.

I spend a lot of time pulling these out, they seem to seed anywhere and everywhere.

Balcony, seems you have similar idea to me. I also volunteer & tend a border at a charity

I plead guilty to letting rose bay willow herb flower in the border

To be fair that border is also home to Rosa Rugosa & buddlia so it helped with the insect friendly theme

My neighbour has MS David so I know how much things like a pretty garden makes all the difference .well done I'm sure its appreciated ..

They look lovely covered in rain drops ...

Thank you all for your comments & especially to SBG for the id! I'll have a look for some seeds & grow a few plants on the balcony next year.

I was especially impressed seeing them covered in raindrops! Being that the main reason for taking the photos.

That is good Balcony, gets you out for a few hours and the colour brings enjoyment to others, I think you'll find the seeds easy to grow, they pop up easily in my garden, depending on where they've self seeded as to whether I pull them up or leave well alone, a weed to one is a lovely plant to others.....

"a weed to one is a lovely plant to others....."

Which is why I put weeds between inverted commas! After all a "weed" is no more than a plant in the wrong place! Like a rose in the middle of your cabbage bed or a cabbage amongst your choice roses! :D)
