they do actually,i planted some mazar i sharif out in the local mountains in a plant em and come back in the fall since it was pretty deep in not to mention the 3000 feet of elevation gain from the parking area...they did great right up until the rippers got em...which was dumb since it was a seed crop so i could just sow them anywhere there was water nearby,there would have been free weed for anyone who cared to hike in....
