I didn't say that it was Horseradish; I only asked if Lawrence had ever grown the plants.
Looking for Horseradish in Hull, UK I see it is mentioned about 15 times as Armoracia rusticana P. Gaertn., B. Mey. & Scherb. in this link:

Perhaps Lawrence could take a few of the leaves from his NOID plant and compare to those on the plants growing in the allotments? It's just a thought.
