When you think of celery you probably think of a vegetable that has long whitish stalks topped with pale green leaves but that is not the only celery that can be grown in the garden. Leaf celery is an interesting plant that perhaps is grown as an herb rather than as a vegetable so don’t expect the long stalks. Focus instead on the leaves that have the taste of the vegetable celery and are a good substitute for it in soups and stews. The leaves are also used as a garnish and sometimes in salad, although they are generally considered too strong for salad. Although easier to grow than vegetable celery, leaf celery needs cool temperatures and frequent watering. Also known as cutting celery, Parcel, Smallage, Zwolsche Krul, and German celery it is suitable for containers.
