It could be either a warm season vegetable or a cool season vegetable. Celery, Apium graveolens variety dulce, dislikes both frost and arid heat. It is a warm season vegetable where summer is mild but winter is not. It is a cool season vegetable where winter is mild but summer is not. Where winter is cold and summer is hot, it prefers spring and autumn.
Celery is a biennial, which grows vegetatively for its first year, and blooms for its second. Because it is ready for harvest in less than half a year, bloom is not a concern. Any that mature enough to bloom are too tough to eat. Celery appreciates organically rich soil. It needs regular watering. Growth is irregular if its soil becomes too dry, even temporarily.
Celery naturally grows as densely vertical foliar rosettes, or bunches. Its distended and elongated petioles are its primary edible parts. Its disproportionately small leaflets are also edible though. Mature celery grows about a foot and a half to two feet tall. It grows well from cell packs if only a few bunches are necessary. It also grows well from seed.

That’s interesting. I’ve never known anything about how celery grows.

Hopefully, you will not. You should harvest it before it matures, bolts and goes to seed.

It sounds like something we should try here. I’ll buy it at the store.

MIne don’t and I can’t answer for others. I do, but not enough to try to grow any, here.

I sort of get the impression that it takes more effort than it is worth. I can not mention that in the article, but I do not bother with it. There are too many better vegetables to grow.

And here it’s usually plentiful and inexpensive in the grocery stores, most of the year.

It is probably even cheaper for those who read the garden column because so much is grown near here.

Tony I grew celery one year from the root of a head of celery. It grew 6+ feet tall, and it was at least four feet in umbrella-like width. Tons of white flowers, long celery-like thin stems. Beautiful plant. Not edible though. Curious.

It resumed growth where it left off. In other words, it technically grew through its first season, and then bolted and bloomed for its second season, even though it seemed like its first season from the root.
