Answer: There is not much we can do to control the weather, so gardeners often bite their nails through the wild swings of early spring! Try not to worry. There is really nothing we can do now to protect them and in fact most plants handle it quite well despite our worries. You may see that a truly severe cold blast kills back the new foliage on the roses (although it is surprisingly cold tolerant!), and later this spring when the weather settles you may find some tip damage that needs to be pruned off.
Bulbs seem to be particularly well prepared for this type of weather. You may see some tip browning or scorching foliage from the cold but in general they should be fine.
