I am not sure that I have even heard of this before today; but after watching this tutorial, I am going to head for eBay and look for seeds. According to the video, this plant can be used in a number of ways, and has a strong celery taste. (I am wondering if it would work in place of cilantro in salsa ? ) She said that early in the spring, the leaves are tender and can be used in salads or cooked. Later, the leaves can be dried to use in winter soups or as a seasoning for a roast. The seeds are similar to dill, and can also be used for cooking. Even the stem can be used. It is hollow, and she suggests using a fresh cut piece as a straw for tomato juice or V-8 drinks. This is a large sized plant, actually more of a scrum or bush, and can get around 10 feet tall, and comes up early in the spring; so it needs to be planted somewhere that there is plenty of room for it to grow. Has anyone ever grown this perennial herb before ?
