Mammoth Dill (also called Long Island Mammoth) is a tall, vigorous heirloom producing large flower umbels and abundant feathery foliage over an extended harvest window. Its height makes it a striking backdrop plant as well as a prolific pickling dill.
At Flying Rabbit Farm, our Mammoth Dill transplants are grown for vigorous height and heavy seed head production for serious picklers.
