the plants and the winter time

this flowers are still alive in my gardeneven it is winter. What are their names? the last one I wil hope wil revive again.

 

#1 looks like the flower of a drumstick primula, Primula denticulata, but the foliage doesn't match.

 

1. Reminds me of Verbena. Possibly Verbena hybrida. But here it just disappears with cold weather... so I might be miles of.

Verbena hybrid, cactus and Dieffenbachia.
Dieffenbachia are damaged by temps below 50f (10c).

 

what about the draied palnt. It is damaged from the frost. What about cactus?

 

Ariani, the dried plant, the Dieffenbachia, looks like it is dead or nearly so. It is not at all hardy and the cactus probably is not either. These need to be grown as house plants where the winters are cold. Some of the hybrid verbenas are mildly winter hardy and may come back if the winter is not too cold. Often they are planted as annuals for a summer show.
