Hi Jose,

I've found Streptosolen tolerant of only light, very short frosts - to
minus 1C for no more than an hour or two.  Occasionally it will
survive out of doors in SW England if kept fry in winter, since we
have vaguely similar climates - especially in winter, I would assume
you would have similar success.  Streptosolen flowers on growth
produced during the previous season, so any frost damage effectively
reduces flowering potential.  

Cestrum nocturnum is very much hardier and is grown successfully
against sunny walls in many parts of England and Wales as are most
other members of the family.  It will easily withstand minus 5C and I
have known it to survive bitter winters of minus 18C over several
weeks.  In this case, it was killed back to the rootstock. but
reappeared in late spring.  You will have no problem with this or any
of the other Cestrum species and hybrids in your part of Spain.
