Cake & Caviar’s Blueberry Yum Yum strain comes from the classic old-school cultivar BC Blueberry OG. This deeply purple hued flower is densely caked with trichomes and smells like a freshly harvested blueberry. By adding Cake to the mix they’ve created a unique blend of smooth creamy smoke famous to their Cake strain and sweet characteristics known to the blueberry lineage.
