Q.gerber daisy and status and gardenia care for the winter in the high desert.
I live in the high desert in Southern California. Hesperia, Ca.
I have a gerber daisy and a status plant and a gardenia on my]patio
on the north side of my house. I have always covered the gardenia
for the winter, should I bring the gerber daisy and status into
the house or can I just cover them each night for the winter?

The Gerbera daisy will be hardy in your area. They may sustain some damage on the coldest of nights, but that will not harm them at all. They will come back from near death from slightly cooler areas than yours.
The statice plants are annuals, and will likely self seed. If they don't, then you will have to re-seed each year, since they will die off completely.
