There are several species of Mandevilla, some are tender and one is
hardy

M. boliviensis, M. splendens (aka Dipladenia), many hybrid
Mandevillas such as
Alice du Pont are quite tender and will not survive frost.

M. laxa, common name Chilean Jasmine is root hardy to about 5 F.

This comes from Sunset Western Garden Book.
I didn't see any info about 'Sun Parasol' but see if your tag says
(M. laxa)
it should be OK.
