This is a great rose. I've grown it in zone 9 and zone 6 and has done well in both. The red is a nice deep crimson that is really beautiful and the smell is excellent. It also grows nice and tall. Would definitely recommend.

Satisfied with it.

Oklahoma rose is vigorous, and hold roses on strong upward stems. Oklahoma did very well, growing fast and blossoming generously. Blossoms last and the color doesn’t fade away. A sweet fragrance completes the portrait of this very satisfying rose.

Being from Oklahoma, I'm a bit partial to this rose, but for good reasons. If you look at a mature specimen, everything about it says 'hybrid tea'. It's upright, about 5 feet, with blooms one-to-a-stem on long stems and with classic hybrid tea form.
The color is not black at all, but a beautiful dark maroon-red. This productive and vigorous rose has excellent hybrid tea form and a very strong, sweet, old rose fragrance. It's highly rated by the ARS and easy to see why. It's essential for your cutting garden; I've cut a stem nearly 3 feet long once! It's now our official state flower, too. I planted 5 new ones together and can't wait to watch them mature.
It's a magical experience to watch as the dark red buds plump up and spiral open. A must-have hybrid tea for sure!!
