By: Homegrown Fantaseeds Australian Blue crosses homegrown Fantaseeds' prize-winning strain, Blue Haze, with an Australian sativa given to them in 1999 by some friends from down under. Australia is well known as one of the great global spots for sativas. Blue's 90% sativa mother, the "Duck" or "Boesi" strain, contributes a classic sativa high and the clean musk of a lemon grove to this hybrid.
