What are the pros? companion plant, indoors
What are the cons? none, indoors.
I have not tried this leaf celery outdoors or in a greenhouse, but it has done very well in a very large container with Leut hot red Hungarian pepper, placed indoors in an east-facing window. The leaf celery will go wilty if it does not have enough water, but will pop right back up when watered. This helps me to know when it is time to water it's companion, the pepper, which has been producing waves of peppers (about a dozen per wave). The red pepper doesn't seem to change the flavor of the celery much, and we use the celery fresh in salads, pestos, and cooked in soups and stir fry. I always do a fine chop or mince for the celery.
The celery does seem to take a long time to germ and get past a delicate looking stage, but is worth the wait. I cannot estimate the germ rate, because I just sprinkle seeds on top of the soil and keep moist.
This makes a handsome house plant and is yummy,too. Use in moderation until you are familiar with the strength which is more like parsley.
