Campanula idI grew a mixed packet of seeds from plantworld last year

The shape of the leaves and the way that they're forming on the stems suggests C.glomerata to me, but it's just a thought.

And the stem growing up in the centre is an entirely different plant!

No definitely the same plant Moon grower, did think at first I'd maybe pricked out more than 1 seedling but have several the same with just the one coloured stem rising from the centre of the plant, I've googled and can't find any pictures like it, looked in the catalogue not one like it listed either, although did say there could be seeds of ones not listed, suppose I could send them a picture for id:-)
I'll look at glomerata Meanie see if there is one like this, thankyou :-)

Could you get a close up of the variegated foliage? The leaf shape is entirely different to the C. glomerata foliage.

Put another piccy on Moongrower, sorry its a bit blurry, think you can see from this that the leaves towards the base of the variegated stem are plain green glomerata foliage (thanks Meanie) but the other leaves are as you say strangely shaped !!!!!

I wonder if the plants have a virus? I don't think this is normal behaviour.

Think you may be right Moon grower had a wonder round the garden today and had a look at the others, all the glomerata ones have either one odd pink variegated stem like this one or cream streaks and mottling to the leaves, why does this happen? will it clear up on its own, they look quite healthy? noticed today the cream variegation on some of them is changing to green, strange.

Only thing I can suggest is to cut out the variegated stem and see what happens...
Do let us know!

Or you could try propagating it and maybe get a new variety!

If it is a virus the last thing you want to be doing is propagating it.

They were from the same packet of seeds? So it may be possible that they were from the same plant or batch......
My point being that to the best of my rudimentary knowledge a virus cannot be carried in the seed, so it must be a genetic mutation to be carried in the seed so that it appears in all the resulting plants.
As I say though, my understanding is basic
From a purely personal point of view, I would be executing them. But that is because I dislike variegated foliage, unless it is absolutely unavoidable!

You are right Meanie a virus can't be carried in the seed. But it can suddenly appear in growing plants... We have had several of our bulbs in pots showing signs of virus this year. We isolate and give them a 2nd chance the following year, if it happens again out they go.

Did grow these last spring and they were good size plants last year, no sign of the variegation then, I'll do as you say Moon grower and cut off the variegated foliage, maybe destroy the ones that have the streaks and mottling on the whole plant, do have quite a few, luckily only this variety that seems to be affected, thanks everyone for your help, I'll let you know how I get on :-)

Moongrower, I thought that virus was one of the origins of many of our variegated plants?

Funny you should mention that Steragram I've just been reading about that myself,my hosta suddenly threw up a completely white set of leaves, never done it before, and apparently you can pot that part on and have a completely new variety, you learn something every day :-)

Certainly the tulips with streaked petals in the 17th C came about from stock that had a virus. If, as we do, you show at national alpine shows you would be shot for putting anything with virus on the bench.

Some viruses do little harm to the plant, others can kill.

I came across this article on Toad lily virus last year.......

I wouldn't like to think of Simbad getting shot...

Lol, me neither :-)
