ANNUAL. Bouquet dill has early, large seed heads, making it an excellent choice for pickling. Its fresh foliage is wonderful on new potatoes, tomatoes, grilled salmon, spinach, green beans, cucumbers, squash, and lamb chops. The robust, but airy plants reach 30″-36″ tall and have 6″ wide yellow umbel-shaped flowers. Be sure to plant extra for the Swallowtail butterflies! Their caterpillars love dill. Harvesting: Fresh foliage can be harvested anytime until the plant flowers. Cut leaves as close to the stem as possible. Seeds should be harvested 2-3 weeks after flowering begins. Cut flower heads with stem and place in a paper bag BEFORE the seed becomes too mature and falls to the ground.
