I guess you could harvest it before it gets that tall, Rita. Mine never grew that much but maybe that's cus I kept cutting on it. And it grows well in a container, too. Personally, I just love celery more...the crunch, the ability to smother the stalks with peanut butter or cream cheese, chop it up and put it in salads, etc. Yummy! Lovage is good but is best used for seasoning dishes - soups, stews, egg salad, tater salad, etc.
