Hi Kate,
My references show Gravenstein growable in zones 2 to 9. Northern
Texas is in
zone 7, central zone 8, and southern zone 9. Seems like you should be
able to grow this apple,
unless you are at the very southern most tip of Texas which is in
zone 10. I think it is worth a try.

There's more to it than the hardiness zones. Hardiness zones go mostly
by the coldest single day you have all winter. (they use some other
factors to determine the zones)
Hardiness zones are excellent for figuring out which plants will survive
the winter and which may not. Hardiness zones are not good for figuring
out chill hours. For example, zone 9b is what? 25 to 30 degrees? A
location that reaches that temperature dozens of times would accumulate
quite a few chill hours. Another location might only go that low once
all year and be much warmer on the other days. It would still be zone
9b. The farther away from a large body of water the more likely there
will be an occasional night much colder that normal to put you into a
colder hardiness zone.

We rarely see that low a tempature all winter. Thanks
