Since chilling is 40F and below with the weather Florida has been having there should be no reason that lack of cold should prevent planting. Much would depend on the soil as sandy type soils tend to harbor nematodes which can cause problems and eventually kill the plant.
I would stay away from the doubles because I believe the heat will prevent them from opening. However many of the others, singles, semi-doubles, or Japanese should do ok. Bloom will not be as good as your mother's. Most are never that good.
Have your Mother send you a cheapy root, which should be arriving at the box, or wally world shortly and as stated above plant shallowly with eyes above soil. Add a bag of the cheap compost 40 pound bags before planting would be nice.
