Preheat the oven to 450 degrees F (230 degrees C).
Whisk together flour, baking powder, parsley, basil, sugar, thyme, savory, kelp powder, and salt in a large bowl.
Cut in butter with a knife or pastry blender until mixture resembles coarse crumbs. Drizzle buttermilk slowly over flour mixture while tossing lightly with a fork, just until flour mixture is moistened.
Turn dough out onto a floured board; knead 4 to 5 times. Pat dough into a 3/4 inch thick circle. Cut out 12 biscuits with a 2 inch cookie cutter, re shaping dough as needed. Place biscuits 2 inches apart on a baking sheet.
Bake in the preheated oven until golden brown, about 8 minutes. Serve warm.
