Granola is about texture, sweetness, and crunch. I like to also add a bit of rainbow color.
Buckwheat, which is in fact another kind of seed, is a lighter ingredient which, when soaked and dehydrated creates "buckwheat crisps." Buckwheat also offers a variety of antioxidants and polyphenols, which make it highly anti-inflammatory. And lastly what you see in the photo, is shredded coconut, followed by the flower petals.
The edible flowers transform the granola into reminder to take delight in the little gifts in life, and provides a reminder to love yourself and give yourself opportunities to appreciate these gifts! I don't know about you, but the little girl in me loves the idea of mixing flowers into my food! They don't alter the texture or flavor, and provide a pop of color.
