I read a recent comment about re-bloomers not doing well in hot climates. I guess zone 9b would be considered a hot climate. The first irises I bought from a nearby iris farm (no longer in business) were re-bloomers that not only didn't re-bloom, but they all died in the first year.
Still the idea appeals to me, so I bought a couple of pkgs. of re-blooming irises at Costco this past fall and planted them in place of some non-rebloomers that I moved elsewhere. Is there anything I can do to make it more likely that these new irises will re-bloom? The ones I have planted are Beverly Sills (hasn't bloomed for the first time yet); Ozark Rebounder (both bloomed with several irises); Blatant (one out of two bloomed); October Splendor (in bloom now); His Royal Highness (two out of four have bloomed)' ; Concertina (one out of two have bloomed); and Victoria Falls (both blooming).
