Royal Tree
An undocumented strain name with no verified breeder or consistent genetic origin.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Royal Tree appears on dispensary menus and seed listings but has no verifiable breeder, published lineage, or consistent genetics across vendors. The name is also used as a brand by a Washington producer, which adds confusion. Without a certificate of analysis and known source, 'Royal Tree' is a marketing label, not a documented cultivar. Buy based on lab results and how it smokes, not the name.
What we know
Royal Tree is a cannabis strain name that appears in North American dispensary menus, seed catalogs, and online aggregators. There is no peer-reviewed chemotype analysis, no widely accepted breeder-of-record, and no verifiable stable phenotype across vendors Strong evidence[1].
The name is also used as a brand by Royal Tree Gardens, a licensed producer in Washington State. This brand use further obscures searches — a company brand name is not the same as a strain lineage [2].
When you encounter "Royal Tree" on a label, it may refer to that producer's house cuts of other genetics, an unrelated seed line, or a regional name with no international documentation. Without source-seed provenance or a breeder's documented record, there is no way to know.
Why strain names alone prove nothing
Cannabis strain names are used as marketing labels, and they rarely predict chemical composition or effects reliably. A 2022 analysis of nearly 3,000 samples across commercial U.S. cannabis found wide chemical variability within samples sharing the same name and substantial overlap between differently named strains Strong evidence[3]. Two jars labeled Royal Tree from different growers may be chemically unrelated.
The popular "indica vs sativa predicts effects" framework applied to most strain descriptions is not supported by chemotaxonomy or pharmacology. Repeated studies show that indica/sativa labels do not map cleanly onto genetics, cannabinoid ratios, or reliable effects Strong evidence[4]. Effects depend on dose, your tolerance, cannabinoid and terpene content, and context — not the strain's marketing category.
What to check if you see Royal Tree for sale
If a vendor offers Royal Tree, ask for these details:
1. Certificate of Analysis (COA): A lab report showing measured THC, CBD, terpene profile, and residual solvents. This is the only reliable information about what you're buying. If no COA is available, the product is unlabeled.
2. Breeder or seed source: Where did the seed or cut come from? A reputable seed company or documented breeder? A regional producer? Vague sourcing is a red flag.
3. Batch test date: Cannabis degrades over time. A fresh COA (within 6 months of sale) is more reliable than an old one.
4. Vendor reputation: Buy from sources that display full lab reports, not just marketing copy.
Strain name alone tells you almost nothing. Lab results, smell, and your own experience matter far more Strong evidence[5].
Similar documented strains
If you are looking for strains with documented lineage, independent lab data, and wider cultivation records, consider these alternatives:
- Royal Sky — another "Royal"-branded strain name
- Royal Waffle — documented hybrid
- White Runtz — well-established cultivar with verifiable genetics
- Dutch Gelato — widely grown modern hybrid
Each of these has more consistent vendor reporting and, in many cases, genetic testing data available through platforms like Phylos or Medicinal Genomics.
How to report a strain record
If you have a verified breeder record, published lab certificate, or company documentation for Royal Tree, you can help Weedpedia verify this strain. Use the "Flag an error" or "Report a correction" link at the bottom of this page to submit:
- A link to the breeder's official page or seed-bank listing with documented lineage
- A lab report (COA) from an accredited cannabis testing facility
- Tissue-sample genetic testing results (e.g., from Phylos or Medicinal Genomics)
- Published cultivation or breeding records with verifiable provenance
All submissions are reviewed for accuracy and source quality.
Frequently asked questions
Is Royal Tree indica or sativa? Strain names labeled "indica" or "sativa" do not reliably predict effects or chemistry. Genetic testing shows that these categories do not map cleanly onto underlying genetics Strong evidence[4]. If you want to know what effects to expect, check the lab-tested cannabinoid and terpene profile, not the marketing label. Read more: The Indica/Sativa Myth.
What is the THC level in Royal Tree? There is no documented THC profile for Royal Tree. Vendor websites sometimes claim 18–24% THC, which is a generic range that applies to most modern hybrids on the legal market and reflects no specific measurement Anecdote. Always request a Certificate of Analysis (COA) for the specific batch you are buying.
Who bred Royal Tree? No single breeder has published a documented, verifiable lineage for Royal Tree. Lineage claims vary by vendor and are unverified Disputed. Royal Tree Gardens, a Washington-based producer, uses the name as a brand. Without breeder records or genetic testing, claims about parentage are marketing statements, not facts.
How long does Royal Tree take to flower? There is no verified flowering time for Royal Tree. If you are growing from seed or a cutting labeled Royal Tree, expect phenotypic variation. General guidance for modern photoperiod cannabis hybrids — 8–10 weeks under typical indoor lighting — applies to any unknown-provenance cutting or seed Anecdote. Plan to select the best phenotype from multiple plants if growing from seed.
