According to a family member, who is a garlic growing champ, I did indeed plant a hardneck variety of garlic and the growth is an edible “scape”.
Good thing, because I’d already eaten them. 
They were tasty!
I sauteed them in coconut oil with chopped zucchini and used it to top pizza.
They have a mild garlic/onion flavor and the texture is reminiscent of asparagus. I used the bud part too and it was a little tough, I had pickled scapes over the weekend that only used the stalky part so I probably should have omitted the bud.
Next time I think I would just throw them in the jar when making pickled ramps and/or radishes.
Have you cooked with scapes?
That pizza looks delicious!
I have made garlic scape pesto. I used olive oil, scapes, Parmesan, and sunflower seeds. The scapes cover the green and basil portions of the pesto. Delicious !
That sounds delicious! And potent! Does it taste like raw garlic?
It’s not as potent as it sounds. The scapes seem a bit sweeter than the raw garlic!
I love scapes, been eating and selling them for years.
