I’m suggesting Silver Carraway because Ive sighted it before about 8 ks from here on Tantangara trail. It’s almost the same, not quite as perfectly shaped but this is in flower. Both times they were growing near small alpine streams low down, this time n a valley. The numbers here are very high with some densely overlapping plants in many places. I counted approximately 60 quite close to the stream. And I walked back up from the stream and they were still everywhere. Just stunning in flower.
