I came across the following in the comments section while reading upon Canadian Goldenrod (Solidago canadensis) on pfaf.org.
Does anyone have similar experiences eating this plant?

In Denmark, where I come from, Solidago canadensis is an invasive plant, giving quite a lot of problem in the wild nature. I found a fine way to fight it (and love it): in springtime, the very crispy and asparagus-like stems of this plant is a very fine vegetable. Especially for wok-dishes, it is good, and I give it just one-two minuttes. The leaves on the plants at this time are very tasty too. "
