Yes … but they are hybrids. The first year you get the Excelsior plants … but if you then sow the seeds from those plants they’ll be a bit different because they will have been cross-pollinated. 😊
Just like people (and other living things) some of the offspring might be similar to one or other of their parents, some might be more like one of their grandparents or great-grandparents, at least some of which might be the wild form. And yours might get pollinated by bees that have travelled far and wide so one parent could be a wildling even if you don't grow them. The bought seeds will have been bred under more controlled conditions, although I don't think they're an F1 hybrid, which means they might take more generations to fully revert to the wild forms. In other words, if you let them self-seed you'll get an unpredictable mixture
