Hi there, hope this pictures uploaded. Would like to ID this plant that is taking over our pastures in South East BC. Possibly ways to beat it back so grass has a bit of a chance. Very close to the ground, i believe the tall stalks with small flower clusters belong with it, only got a picture of the dried flowers, but they honestly dont look much different from fresh.... seem to grow only a handful of these per sqft of occupied ground. Silvery green leaves in the summer, and silvery white once dry weather prevails.
