Why is celery now grown and sold green rather than white as it used to be?

That's a misconception! Celery has always been grown and sold in both green and white varieties. It's not a recent change.

Here's a breakdown:

* Green Celery: The most common type, with its vibrant green stalks. It has a slightly stronger flavor than white celery.

* White Celery: Also known as "bleached" or "heart" celery, it has a milder flavor. The stalks are blanched, meaning they're covered with soil or a material like burlap to prevent sunlight from reaching them and turning them green.

So, while the popularity of each type might fluctuate, celery has always been available in both colors.
