Depends on the part of Texas you are in. The South Plains (nw Texas) is pretty flat and a little dry..good farming country. Far west is mountains and semi-arid. Central part is rolling hills with lots of live oaks and cedars. South and east are piney woods with lots of vegetation. It's big enough you get a lot of diversity! This time of year, the bluebonnets in the Austin area are just beautiful. Lady Bird Johnson has a wonderful wildflower museum that is worth the visit if you are ever in the Austin area.
