Do you know Texas Rose?

My dad has been growing this in his back yard, in the Myrtle Beach area. It grew very quickly and he has been told by more than one person that it is a Texas Rose. He was also told that the limbs can be cut, put in water till they start to root and then plant. He has had much success with this plant. He said it blooms twice a year with red flowers. This picture is a limb he gave me a few weeks ago. Unfortunately it has lost most of its leaves. When I search for Texas Rose, I can't find anything that looks like this. Please help. Does anyone know Texas Rose?
Thanks

This is my first posting. If I need to post a new picture, I will be glad to do so, just let me know what I should do and/or you need to see.

Probably Hibiscus mutabilis (aka Confederate Rose). It's marginally hardy in our area... will usually get killed to the ground in the winter and then grow back from the roots the next year. You should get flowers in late fall. Farther south where it's warmer the branches will live through the winter and you'd see more flowers.

That looks like Confederate Rose to me and if so you should have no problem taking a cutting and rooting.

Only thing is they bloom in earily fall till the first frost not twice a year to my knowledge. I could be wrong on that.

i hope this works

that is hibiscus mutabilis. it grows into a lare shrub here

The leaves are a dead give-away---that's Hibiscus mutabilis---the good old "Confederate Rose". I'm sure Texans call it "Texas Rose", but if you look up Hibiscus mutabilis, or Confederate Rose in any decent garden book, it should tell you all you need to know. Here in Charleston they start blooming in early October and bloom through the first killing frost. My plant died back to the roots the first year planted, but hasn't died back that far since. It usually gets nipped by the cold back to about 3-4 ft, and growth springs from there the next year. They can get huge here in Charleston; mine is 20' tall by 15' wide (7 years old), and is a joy to behold in October /November. I'm going to whack mine back to 2' this winter---it's starting to shade too many other plants. Who knew it would get that big??
