What am I growing?

I know GG The shame of it!

Whatever it is, it's definitely time it was planted!

Looking at the leaves and growing pattern, I’d say it was a variety of Campanula.

It isn't some variety of delphinium is it?

Thank you both, you're right

I've just looked at some photos online and I think it's Electric Blue.

Mine probably looks more delicate because it needs repotting

It does look similar, fiorentina, but it's not as sturdy looking, if you know what I mean! It looks more delicate and the flowers are smaller than the normal penstemmon flowers.

I'm cross with myself for not labelling it! I don't even remember buying it, but it's in a 'shop/nursery' pot, as opposed to one from my garden, so I must have bought it!

Yes, I also think it is a Penstemon. I like that colour.

I think it might be a Penstemon.
