Traffic Jam is a Preferred Gardens flower release, and the interesting part of its record belongs to the brand rather than to the pedigree. The circulated lineage is Biscotti x Sherb BX x Jealousy, but Preferred Gardens has never published it, so treat that notation as menu convention rather than breeder record.
Where It Comes From
Preferred Gardens is a California legacy operation: founded as a brand in 2015 by David Polley, with cultivation dating back to 2005 and a long run through the medical market before licensing arrived. The company describes itself as family-owned with no outside investors, running mixed-light greenhouse production alongside indoor.
The detail that matters for a strain page is how the company sources genetics. Preferred Gardens states its library exceeds 260 strains, none of them purchased from nurseries, all bred in-house or pheno-hunted from seed, with roughly 200 seeds evaluated a month. Traffic Jam appears in that catalog as a branded flower release, consistent with a house selection rather than a licensed cut.
One practical warning before you shop. Traffic Jam is a common enough name that unrelated cultivars circulate under it from other producers, so check the brand on the jar and not just the letters on the label.
The Cross
Preferred Gardens is the producer. No breeder credit is published for the cross, and the brand has never put its own name to the lineage most menus print, so the pedigree stays a shelf convention rather than a record.
If the circulated lineage is right, the pieces do fit together. Biscotti sits in the Cookies orbit and contributes dense structure and dough. Sherb, commonly meaning Sunset Sherbet, brings the fruit-and-cream half of that family. Jealousy, the Seed Junky Genetics release usually documented as Sherbert BX1 crossed with Gelato #41, brings the sharp modern edge that runs through most of Seed Junky's recent work.
Flower is generally shown dense and resinous, mint to dark green with purple flashing late and burnt-orange pistils. Those traits are common across modern dessert-and-gas hybrids and should not be read as identifying marks. Batch figures on listings have run from the mid-twenties up to 27.39% THC, and each of those numbers describes one lot.
What It Left Behind
No competition placement is documented for Traffic Jam. Its footprint belongs to the brand more than to the cultivar: Preferred Gardens' pheno-hunting program is the actual story here, and Traffic Jam is one of more than 260 selections that came out of it.
A house that hunts its own seed at that volume earns some benefit of the doubt on an unpublished cross. It also explains why the lineage never got published in the first place, since a plant pulled out of an in-house hunt does not arrive with a certificate attached.
The High Rise Take
Traffic Jam is worth buying on the brand's track record, not on a lineage nobody has published. If the pedigree matters to you more than the grower does, this is not the jar to start with.
