    Difficult seeds  do seeds directly acquired from the southern hemisphere 
and which normally germinate in late fall/winter there, when planted in the 
northern hemisphere fail to germinate in northern fall, but germinate in 
northern spring?  If this is the case, and vice-versa for northern species 
sown in the southen hemisphere, then natural circadian rythyms would be the 
cause.  Mr Ingram's message seems to indicate this is a problem.  I also had 
what is now a winter growing Herbertia germinate in the spring and grow in 
its first summer, eventually becoming summer dormant.
