It is inveterately persistent when once established, and may easily become a pest. For forage it has little merit where other things can be grown, for it is too coarse. For planting in rough places, where a thick cover is required, it is one of the best of all her- baceous perennials. It is perfectly hardy in the North and seems to thrive anywhere. P. SiehohJi was once distributed as Sacaline, but that species is much smaller, with smaller, shorter and square-based leaves, and with more profuse bloom. .543; .iOl: 45, , up to ft. .159. L. H. B.
