I love these, although I don't have one blooming every year, when one or two do the whole garden is filled with their fragrance. Once they bloom they die but not before the send out pups, which can take up to 4 years to bloom (7 years from seed). I have two different varieties, One the new foliage is green, the other at first it's bronze then turns a dull green, the green one stays a little on the shiny side. The bronzy one doesn't get quite as tall. A picture of one of them.
