Preheat oven to 400℉.In the bowl of a mixer, add the dry ingredients (Flour, Half of the Sugar, Baking Powder, Salt, Baking Soda, and Lavender). Mix on low until blended.In a separate, small bowl, add the remaining Sugar and Lemon Zest. Rub the Zest and Sugar together, until well mixed and the scent of Lemon is bringing a smile to your face. This step will help infuse the lemon flavor and bring out the natural oils of the lemon. Add Chopped, Cold Butter. Mix until the butter is pea-sized, and the mixture resembles coarse crumbles.
In a measuring cup, mix the Lemon Juice into the Heavy Cream. Stir and let sit for a couple of minutes. It will turn into a buttermilk consistency. Make a well in your dry ingredient mixture. Add the Cream/Lemon Juice mixture. Blend until just combined, taking care not to over-mix. Dump mixture onto a sheet of parchment paper. Gently form it together into a ball (do not over work the dough). Press it into a rectangle and fold the two horizontal sides over each other, as though you are folding a letter. This will help form the layers.
Press the dough into a rectangle, roughly 8" x 6". Cut the rectangle down the middle, lengthwise, so that you have two long rectangles. Then, make two vertical cuts, dividing your dough into thirds, so that you have 6 squares. Cut each square in half diagonally, so that you have 12 small triangles.
Transfer Scones to parchment lined baking sheets. Take care to leave 2" - 3" of room between scones, as they will expand and rise during baking. Brush with Heavy Cream and sprinkle with Turbinado Sugar.
Bake for 18-22 minutes, until the both the bottoms and tops of the scones are golden brown. Remove from oven and transfer to cooling rack.
