Pampas Grass(south america)

it's a invasive plant very disturbing when the flower's are losing the plumes,whith a litle wind,it's like snow in the air.
Spoted near my house in a abandoned agriculture field,now used to park trucks.it's spreding in this place more than normal.I usualy i see her in gardens and one or two times in fields like this
