oh yes, i harvest them for sautes, salads, tea

the bunny rabbits really like my weedy yard
but the canada thistle is a demon weed that's invasive and came from Lowe's mulch that i was foolish enough to buy.

it's a real problem and others seem to be dealing w/ it here to the point of bulldozing their yards and starting over

saw this meme yesterday in au, short and sweet!

Wow, I feel your pain ... we used to go to the farms and get animal's "fertilizer" and mix that into the soil, all turned up, then anchor newspaper over it to block the sun ... until all the mystery seeds died ... then when the soil was ripe, plant away - good results took a couple of weeks before we were sure the bed was clean.
