Sweet Blueberry Yum Yum X Sweet Blueberry Yum Yum “Got a lil' bit of Blueberry Yum Yum, and I never would’ve thought that it could taste this good,” muses Atlanta-based rapper Ludacris on his hazy 2004 stoner anthem paying homage to this coveted strain, aptly named “Blueberry Yum Yum.” Although the original breeder is unknown, Blueberry Yum Yum is a reported indica-leaning cross of Blueberry and Durban Poison. Carrying an aroma of earthy pine, this strain is said to translate into a delectable berry flavor upon consumption.
