I thought, when I saw this, that it was some kind of ornamental artichoke but when you look down at the leaves it was clearly something else. The broad leaves with their slightly silver coating were obviously those of a hosta. This is the stalk that supports the flowers that are soon to emerge, they will appear between the leaves and are small and white and rather unspectacular.
