Oh, 100 years from now I fully expect irises to be ever-bloomers, the form will undoubtedly include appendages that will be consistent, all haft areas will overlap, there may even be petaloids that come up through the style arms giving the whole flower 3 more petals. Iris leaves will come in variegated form of white, green, yellow, purple, and maybe others.
Sci-fi thoughts for 100 years from now:
We will be able to change the color of the flowers with special fertilizers.
People will be sick of RED colored irises and would prefer the new neon shades
Substance will be so tough, a Tsunami wouldn't tear a single petal.
Iris shows will have holograms instead of true stalks (which will make transporting irises to the show much easier)
Iris gardens will have climate control and robotics to maintain the garden and growing conditions.
100% of viable seeds will germinate and bloom in 6 months time.
Iris flowers will be the size of dinner plates.
