defensive hairs, etc. than the seedlings from the
ungrazed ones. Like some inherited defensive mechanism
had been turned on.

Well now, that's the best rationale I've seen for hybridizing irises up here in NOT Iris Heaven! I wonder how many generations it would take for irises to come up with an effective defense mechanism against deer grazing? ;-)
