misshapen celeriac leaves

[mskrieger]

I'm growing celeriac for the first time. It's the 'Tellus' variety offered by Adaptive Seeds in 2014. Most of the leaves on most of the plants look very typical of Apiaceae--in fact, the plants are hard to distinguish from the parsley growing beside them. But some of the celeriac leaves look misshapen...they're curled down (imagine a hand with its fingers pointed down as if it's clutching something.) Is this a virus? A mosaic virus, maybe? The carrots and parsley growing alongside the celeriac all seem fine, and not all the celeriac has the misshapen leaves. In fact, some of the affected celeriac plants only have a few altered leaves, the rest seem normal.

So...anybody know what it is? (Sorry that I haven't been able to figure out how to post pictures on here yet.) And what should I do about it, if anything? I'm tempted to watch the plants and see if it has any effect on their growth, but will this eventually affect all the Apiaceae members in the patch?

Re posting pics - you need to use an online picture host, like picasa or flickr, upload your pics to them, then use the 'insert picture' button when posting and paste the url link of the picture into the box.
Re the celeriac, are there any aphids or something on the underside of the leaves?

Thanks for the tip. I don't have that type of picture account at the moment, so I'll remain imageless for now.

Good question regarding the aphids. It does look...kinda...like it could be aphid damage. I haven't seen any, though. My garden has had a posse of ladybug larvae on patrol recently. So maybe they swooped in and cleaned up? The problem doesn't seem to be spreading to other plants.
