Dill is a hardy, fragrant annual that grows from two to four feet high. Stems are smooth, ribbed, hollow, and have a bluish-green cast. The finely-divided linear leaves envelop the stem with a thin sheath. Tiny yellow flowers grow on terminal umbels up to 8 inches across, making for a very attractive plant. Chopped leaves great in salads, with sour cream, cucumbers. Seeds for dill pickles.
