Can you ID this, please?

This is one of my $1 hibiscus I got at Lowe's. I'd love to know its name and whether it's hardy or tropical,since it's starting to get cool here. It was tagged as a "Patio Performer" and says to bring it in if the temps drop under 50. I've read about telling the difference in hardy (matte leaves) and tropical (shiny leaves), and judging by that, if that's true, it would be hardy. The leaves are oval shaped and matte.
It's not the most beautiful bloom I've ever seen, but I'm really tickled with it, just the same. This is my first year growing hibiscus and I absolutely love them!
Thanks!

This one is a tropical (rosa-sinensis) hibiscus. It's name is Cairo Apricot and was developed in Europe many years ago forming part of the Cairo Serie.
Seeing your zone, it's time to bring it indoors.

Thank you so much, Carlos! Is there a place where I can find more information on the Cairo Series?
I had another one bloom yesterday and it has the same form as this flower, but a bit more yellow than apricot. It may be the same thing with just a bit of variance in the bloom color. Both hibiscus have more buds ready to open today or tomorrow, so I'm anxious to see what the exact coloration will be on these blooms. Maybe they'll open on the same day so I can compare them side by side.
Again, many thanks!

Here you have a pair of links. They are mixed with other series or clasified by color.

Thank you so much, Carlos! I've discovered that three of my four are Cairo Apricot. I think the blooms are much prettier now, though. Better shape to them. I'm really hoping the last one is Cairo Rose. That color is beautiful! It's still a week or so from blooming, though. Hopefully, the weather will hold out to allow it to bloom before I have to bring it in.
Below is the newest bloom.
Thank you for all your help!

WOW! That plant is beautiful! Lovely color :)
