Foreign Statesman
'Foreign Statesman' (Sterling Innerst, R. 1992) Sdlg. 3319-1. TB, 36" (91 cm), M. Full purple; beards purple blue, tipped bronze; slight fragrance. 'Titan's Glory' X 'Twice Delightful'. Innerst 1993. HM 1995.
It is interesting to note that Sterling did not comment or note PBF in his introduction and it is not part of the AIS description above. This is surprising because of how prominent it is on it, especially at this time of year. Here are the pictures ( taken 11/11/13).
As you can see, the PBF extends to the rhizome as well which I think is a very special/neat feature as I have personally hardly ever seen this feature.
