In a similar vein to the Teasel discussion I'm growing salsify as a root vegetable crop. Considered a weed here it's a delicacy in Europe.
I've been diligently removing the seeds from the seed head and have collected enough for a lifetime.
But I'd like to add them to my wildflower meadow as the flowers are wonderful and the seed head spectacular but the seed is probably going to escape from there.
So do I grow them in the meadow or continue to control them in the veg garden?
