"Ledger's" is the only iris japonica I've grown....and as mentioned, that was in SoCal where there was no question as to what to do with it, just stick it in the ground and it does fine...so when Lee-Roy asked me about it, I drew a blank as to what zone or any other conditions it might like...it might do well here in my new zone area, did not bring it with me when we moved so I haven't given it any thought.
@henhouse....hahaha...my Mom said it was my Dad who filled out the birth certificate and the only "Sherry" he knew was for drinking...she had intended to spell it Cherie....
These things should not be left up to men.....my friend named her daughter Leland and her artist husband, paying no attention, designed cards which he sent out to everyone stating the daughter's name as Leyland...because to him it was natural to think British Leyland....
