Seeds starting

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.
