Erythrina herbacea no guessing

It's not unusual for dormancy to be used by plants to protect themselves
against cold. Here it is just the seed. All the proteins and fats are there
but water is not. Tender annual or perennial seed is regularly exposed to
frost without damage from the cold, per se.

I potted up those seeds in February 2010.  So they withstood winter temps
for two winters... albeit a short 1st winter.  Based on PBS feedback it
seems impossible for those seedlings to have wintered over, so the seeds
must have germinated this spring.  That's fascinating (to me) to have hardy
seeds from a non-hardy plant!
