Oh thankyou - such a pretty plant has some uses to redeem it in our plant kingdom - it can be brewed or eaten.
The First Nations used it here, mostly the seed fluff for weaving or padding.
Several ate the central pith in early spring. The Haida made twine for fishing
nets from it.
It was French Canadian voyageurs who called it asperge and cooked it.
I have a little patch growing in my garden. It has not spread much in the 20
years or so it has been there.
