[edit: Actually it was not a celery plant, it was a parsley plant.]

That was the first time I had seen iron deficiency symptoms, in
the first leaves to develop under the growing tips. I had read
somewhere that parsely [not celery] was high in iron (for a
vegetable), and I had several good-sized volunteer
parsley [not celery] plants growing at
different places in the garden, so sacrificing one was no real
loss.
