I grew a Caramelo- it's Lavender x Indica. Purple and delicious, but tasted sweet Lavender not fruity, probably like your Mendo Purps, and Querkle, too. I never tried Blackberry, tho. Fruitiest I've grown may be Kushberry (DNA), but it's not strong. That's just my two cents. - Some I have at 7-8 wks that smell outstanding are Royale Haze, Diesel, and Lablanca. Those are various freebies that I had low expectations for but each is sweet and sticky with good yields showing. Best two I have are crosses I made- Grapefruit x Agent Orange and Missing x Agent Orange. Smells like the Marmalade factory in there, Grfruit x AO is among the frostiest I've seen, and only at 6 wks. Orange Sherbet all the way, just started 3 more seeds of it. You may think about some singles from pick and mix, like Agent Orange, Blackberry, and Strawberry Diesel. But I like Lavender, too, the taste is addictive for me.
Not much help, I suppose- there's so much out there. I got a huge variety of female singles and also got enough TGA males to give me more seeds than I'll ever use, with some great crosses. Try it, you'll like it!
