Orange Tart
A citrus hybrid with unverified lineage circulating under one name across multiple breeders.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Orange Tart is a descriptive name, not a registered cultivar. Multiple unrelated crosses probably use it. The citrus aroma is real and inherited from Tangie-family genetics, but claims about its specific parents, THC%, effects, and breeder are marketing folklore without primary sources. Buy it for the smell, not the story — and check the lab report.
What we know (and what we don't)
Orange Tart is sold at dispensaries and seed banks under a single name, but no strain database, breeder website, seed company, or published record documents it as a distinct, verified cultivar. No data
The name itself is descriptive — 'orange' flavor and 'tart' (sour) character — rather than a proprietary identifier like 'Gorilla Glue #4' or 'Girl Scout Cookies.' That descriptive quality is significant: it means any grower or seed company can label a citrus-forward cross 'Orange Tart' without reference to a single parent lineage or genetic test.
Vendor descriptions are consistent on one point: a sharp orange peel and citrus aroma, often attributed to Tangie genetics. Anecdote Tangie itself (California Orange × Skunk) is a real, documented cultivar popularized by DNA Genetics. Weak / limited That genetic link is plausible, but it is not confirmed for the specific Orange Tart product(s) you might encounter.
THC%, CBD%, terpene profiles, flowering time, and yield figures all vary by source and sample. Dispensary menus report these numbers from certificates of analysis (COAs), but COA rigor and lab accreditation are not uniform — two jars of 'Orange Tart' from different suppliers may have genuinely different chemistry, or may have been tested at different labs with different standards.
Why strain names are unreliable
Cannabis cultivar names are not protected like plant variety names in horticulture. A breeder can release a strain, but anyone can grow seed from it and re-sell plants or seeds under the same name, with or without genetic testing to confirm identity. Disputed
Research on cannabis strain databases has shown that the same name circulates for genetically distinct plants, and the same genetics get labeled under multiple names. [1] This is especially true for older or popular strains, and for descriptive names like Orange Tart that could apply to dozens of crosses.
If you want to know what you're actually buying, a certificate-of-analysis-coa is your only real tool. But even a COA only tests the sample submitted — it does not confirm that future purchases under the same name will match.
What to check if you see Orange Tart for sale
- Lab report (COA). Does the dispensary or seed bank provide a current lab analysis? Reputable sellers post them. Look for a lab name, batch number, test date, and specific cannabinoid and terpene values. Strong evidence
- Breeder or seed company. Who produced this seed or plant? Can you find their website or a verifiable social media presence? Are they willing to describe their breeding lineage? If they say "Tangie × Triangle Kush," ask for a primary source (release notes, breeding notes, or pedigree).
- Batch variation. Ask the seller if they have access to multiple test results from different harvest batches. Do THC%, CBD%, and terpene ratios stay consistent? If they vary wildly, you're likely looking at multiple unrelated plants sold under the same name.
- Comparison. If you're interested in the citrus-forward, Tangie-descended flavor profile, documented strains like orange-butter, orange-muffin, and orange-waffles may offer more transparent sourcing and breeding claims. These are equally undocumented at large scale, but some breeders make them under clearer pedigrees.
Reported effects and the indica/sativa problem
Vendor descriptions and user reviews characterize Orange Tart as uplifting, energetic, or talkative. These are flavor and subjective experience cues — useful if you like citrus-forward cannabis, but not medical claims. Anecdote
Orange Tart is often labeled "sativa-leaning" or "sativa," implying energetic effects. The Indica/Sativa Myth is worth reading in full: modern genetic and chemical analysis has shown that the indica/sativa label does not reliably predict effects or chemical profile. [1][2] Sativas and indicas can have similar THC%, CBD%, and terpene profiles, or very different ones.
There is no peer-reviewed study of Orange Tart specifically, and there is almost none for any named strain. Strong evidence Cannabis research studies defined doses of THC, CBD, or whole-plant extracts — not branded cultivars. If you're interested in cannabis for symptom relief, THC% (dose) and personal sensitivity matter far more than the strain name.
If you have breeder records or lab data
If you are a breeder, grower, or seed company associated with Orange Tart, or if you have access to a verified laboratory report, breeder pedigree, or genetic analysis (e.g., from Phylos or another cannabis genetic testing service), please flag an error on this page with that documentation. This article will be updated as soon as credible primary sources are available.
Until then, Orange Tart remains a well-distributed name without a confirmed parent lineage, registered breeder, or independent laboratory standard.
Frequently asked questions
Is Orange Tart a sativa or indica?
It's usually labeled sativa or sativa-leaning, but the indica/sativa label doesn't reliably predict effects or chemistry. The reported terpene profile (terpinolene-forward) is common in both, and THC% is what actually drives the strength of effect.
What's the THC level?
Vendor reports range from 18% to 24%, but these come from different labs and batches. Your actual product could fall anywhere in that range or outside it. Check the lab report on the package.
How long does it take to flower?
Growers commonly cite 9–10 weeks indoors, but this is not verified by any published cultivar record. Actual flowering time depends on light cycle, genetics, and growing conditions.
Who bred Orange Tart?
No single breeder or company has published a documented pedigree for Orange Tart. The name is descriptive and has been used by multiple seed companies or growers. If you want to know the source of a specific seed or plant, ask the seller directly and request a breeder pedigree or lab genetic fingerprint.
