Guess what - seeds from irises that <will> grow and thrive in iris
heaven are easier to germinate than seeds from irises that will grow and
thrive 'east of the Rockies'.
p154
"Seeds of Purissima derivatives and pink-buds [elsewhere she refers to
'shell pinks'] may come up almost 100% in the first year." Seeds from
these sources will also germinate within a week or two when planted
immediately (fresh from the pod).
Other types of crosses may have very few seeds germinate <at all> the
first year.
The only other type of TB cross she mentions specifically in relation to
germination are amoenas, which she says are notoriously difficult to
germinate and may die before enough years go by to eliminate the
dormancy factor. Since this was compiled in 1961, I guess she is
probably referring to recessive amoenas.
Based on what I read in the other two books, ecological adaptations to
variable climate results in seeds with dormancy that is harder to
break. These seeds wait until they are <sure> spring is here. Very
hard to fool them, which is why most folks outside iris heaven harvest,
store, & plant in late fall, letting nature do the work.
