Adam: Dykes crossed them and got several nice cultivars, all of which I believe have vanished.

These two irises are most unlikely to yield any seed whatsoever.  The 
chromosome numbers are really incompatible.  I.  lazica has a 2n = 32. but 
could be a tetraploid and unguicularis has a 2n of 40 or 50.  I can't 
imagine quite how a matchup could occur,  Really odd linkages and matches 
occur in some plant groups but I've not known this to occur in irises

OK, I done the deed: Iris lazica was pollinated yesterday with pollen from
I. unguicularis. The reverse cross was not made because the flower of I.
unguicularis seemed to be past using for that purpose.



It occurred to me the other day that Iris unguicularis is virtually unique
among the irises I know for its prolonged season of bloom. Here flowers
appear over a five month period: does any other iris come even close?
Imagine a hardy garden iris with a five month season of bloom! Has anyone
ever attempted crosses of I. unguicularis with bearded irises?  Imagine a
bearded iris which continually put up flowers over a five month period.
Those genes for prolonged blooming should not go to waste!



Does Iris lazica bloom over an extended season, or do the flowers come
mostly at once? The first two flowers to appear are fully formed now, and I
see more buds pushing up. Can anyone give me an idea how long this will
continue?
