Can you root a cutting from a Texas Star Hibiscus?
I don't know about that. But why don't you just collect some of the seeds and plant them. A friend of mine gave me some of the Texas Star seeds last year and I got some germinating already.
I have never even thought of rooting them from cuttings. They grow from seed so easily, it just seems like that is what we are supposed to do.
Do you have seeds? If not, email me with your snail mail address, I have a few I can share. I will go out and look at my Texas Stars in the morning to see what I think of rooting some cuttings.
