I started this brug from gifted seed a year ago. Forgot it. It grew. and grew. So I transplanted it to bigger pots all winter. When it got warmer, I put it outside in a bigger pot, and a bigger pot still. Now it's about 5' and still has not bloomed. I'd like to know if I can overwinter it in an unheated garage. I keep roses in there all winter, they will often keep their leaves all winter so I know it does not get too cold. Its way to big to bring into the house with the other tropicals and does tend to attract every aphid in a 20 mile radius....
Suggestions needed!
Thank you!
