Dear David, the Hipp#4 of my photos is very unlikely to be such a complex hybrid you say. Indeed it is more likely a pure species, possibly a form of striatum. Flowers are rather small and 2 per stalk, which is quite common for pure species. BTW this plant is evergreen for me here, having withstood routinely lows on -2°C for many nights. All my x johnsonii and other hybrid go dormant at first frost, except aulicum which is winter growing. Arnold's one looks like Bestseller to me. Angelo Porcelli Italy
