Apium graveolens...

...leaf or bunch celery and one of the oldest plants used by people.

First recorded in 850BC in Homer's Odyssey, and previous to that in garlands in Tutankhamun's tomb ,the bunch loitering at the bottom of the crisper box are not quite that old but obviously liked the dark and cool enough to start growing little stalks in the big stalks!

My friend S gave me a fab book 'What Food Is That and How Healthy Is It' by Jo Rogers and it is chockers with information on everything from fruits and fungi, poultry and pasta, cheeses and cereals to fats and fish.

Anyway back to celery which was originally not eaten as a food but as a medicine throughout the Middle Ages. Cultivated for eating in the 16th century in Italy but hey it was stringy!
So the clever clogs in Utah developed stringless celery.

Delicious stuffed with blue cheese or here in Aus, peanut butter in a lunch box.
