Can they be harvested to eat all season, or are they best before the flower appears?Bearclaw said:You dig them up, trying not to cut or gash the bulbs which are underground. When they're young, like now, I use the whole plant; the leafes are still tender yet. Wash them off real good especially between the leafes were there is dirt. Trim the roots off and your're ready to go. I just stuff as many as I can in a big frying pan with some melted butter and fry them slowly till they're nice and soft. Maybe alittle salt and pepper. In the northern parts of our state in May many places have ham and leek dinners. Some very good eating; deinitely worthwhile if you get the chance to go to one. As the plant gets older a long flower stem emerges from the middle and has a small cluster of flowers through the summer turns into a seed pod in the fall.
