Cultivation of Celery started around 3000 years ago in the Mediterranean coastal marshes.  Originally it was grown as a medicine, said to help with toothache, insomnia, anxiety among other things.  It was first used as a food proper in Italy during the early 16th century.  The first written mention of it comes from France in 1623, it was not until 1664 in England that ‘sellery’ is found in text.  Introduced into the USA in Kalamazoo, Michigan in 1856 by George Taylor a Scotsman.

Traditionally celery was grown in trenches to keep the light off the stalks and give it a sweeter flavour.

All parts of the plant are edible – stalks, leaves, roots, and seeds

Celery is a member of Apiaceae or Umbelliferae family ans thus is related to fennel, carrots, and parsley


Germination can take a long time, up to a month so patience is required when growing celery from seed.

Prick out when plants reach 5cm.

Blanch stems – 3 to 4 weeks before harvesting wrap in black polythene, cardboard, or newspaper to 40 cm and tie off.  This is said to sweeten the taste.

Celery can be used as a pick and pick again vegetable.  Cut what you need from the outer stalks and leave the rest to continue to grow.  Cutting off the whole plant off at the base it will re-sprout but not be as big.

Storing harvested celery:  Can be kept in a cool dark place.  Store in fridge up to two weeks (cover with water for a longer storing time)  Can be canned (fair taste), frozen (good taste)  or dried (good taste)

Seed Saving:  Insect pollinated.  Isolation distance of 1km.  30 plants recommended for genetic diversity.  As it is a biennial seed is harvested in the second year and plants may be difficult to overwinter.

Seed Life:   Five years
