Matt Porter, who specialises in growing and preserving poisonous herbs,
"I harvested after the plants went to sleep for the year. The smaller potted plant is water hemlock and the larger one is poison hemlock. The whole root inside the jar is the water hemlock root and the other root is the poison hemlock root. I thoroughly enjoyed growing my hemlock this year and last year and found it quite low maintenance when it came to its upkeep. I kept all of the leaves and flower head cuttings and dried them out for my altar and ritual uses."
