In a large mixing bowl, combine flours, sugar, baking powder, salt, and cream of tartar, whisking well. Using a pastry blender, cut butter into flour mixture until it resembles coarse crumbs.
In a liquid-measuring cup, combine cream and rose extract, stirring well. Add to flour mixture, stirring until mixture is evenly moist. (If dough seems dry, add more cream, 1 tablespoon at a time.) Working gently, bring mixture together with hands until a dough forms.
Turn out dough onto a lightly floured surface. Knead gently 3 to 4 times. Using a rolling pin, roll dough to a ½-inch thickness. Using a 2-inch fluted round cutter, cut 15 scones from dough, rerolling scraps as necessary. Place scones 2 inches apart on prepared baking sheet.
Bake until edges of scones are golden brown and a wooden pick inserted in the centers comes out clean, approximately 15 minutes.
