Hi all,

In one of my veg paches I left a 1/2 doz cellery plants standing.
I'm intending to let them go to seed.I want to make fresh
cellery salt to sprinkle on tomatoes.

The cellery plants have now been in there for 12 month
are very big, but no flowerbuds to see.
Is cellery bi annual?,does it need special condition to flower?

Any insight is appreciated

Mathew
