The fruit flavours that experienced users detect in different strains include grape, mango, blueberries, strawberries and even strawberries. On the whole, it's the strains with a good proportion of Sativa in their genetics that tend to produce recognisably fruity flavours. The Indica dominant types are much more closely associated with hash-like, earthy tones, often with a hint of mustiness.
Sativa dominant strains have a reputation for being harder to grow than Indicas, and of taking longer to mature. But if it's that exotic fruit flavour you crave, the extra effort and time will be well worth it.
One strain worth trying is Strawberry Cough, a Dutch strain created by master growers by crossbreeding Northern Lights #5, Erdbeer and a Swiss Sativa. This weed has notes of strawberries and exotic spices, and packs a powerful hit.
Blueberry is another one for your list if you're a fruit lover and this strain has been a favourite since it took first place in the High Times Cannabis Cup back in 2000. Naturally enough, it has a distinctive blueberry flavour, and as a bonus gives an intense, euphoric stone. Lemon Skunk, the multi award winning strain is another real case of "the name says it all", a rich and sweet Lemon scent comes through quickly settling into a more sharp citric taste on the exhale.
