Lemon Royale strain guide
Lemon Royale is a sativa-leaning hybrid from Swamp Boys Seeds, a cross of Lemon Tree with a GMO and Triangle Kush plant. People know it for a loud lemon smell over gas and funk, and an energetic, clear-headed feel.
Where does Lemon Royale come from?
Lemon Royale was bred by Swamp Boys Seeds (sometimes written Swampboy Seeds), a US breeder. Sources agree it's a cross of Lemon Tree with a plant that was itself a cross of GMO and Triangle Kush.
Lemon Tree brings the citrus, while GMO and Triangle Kush add funk, gas and body. You'll sometimes see it as Lemon Royale #11, which points to one selected plant from the line, or shortened to LR. It has been used as a parent too, with 91 Royale listed as an offspring.
What does Lemon Royale smell and taste like?
Lemon is the headline, sharp and strong, and people often say it comes through on every pull. Underneath sit gas, skunk and a musky funk from the GMO side, with some pine and kush on the inhale.
Published terpene data lists limonene first, followed by caryophyllene and myrcene. Limonene gives the bright lemon, caryophyllene a peppery bite and myrcene an earthy, musky base. The exhale often brings citrus back with a peppery, savoury finish.
Lemon Royale effects: what people report
People most often describe Lemon Royale as energetic and uplifted, with a happy, clear head that many save for the daytime. Reviewers mention feeling focused enough for long work sessions, with some creativity and euphoria, and a softer body buzz that eases in later.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth and dry eyes are the most common complaints, and some people mention a headache.
How strong is Lemon Royale?
Lemon Royale is a high-THC strain. Published listings put it at about 26% THC, with one tested flower product listed at about 28%, and very little CBD. Growers describe dense, frosty buds that can look almost white.
If you're new to it, start with a small amount and give it time before having more. The numbers on your product's label matter more than the strain name, and our THCA vs THC guide explains why labels show more than one THC figure.
Buying Lemon Royale in Canada
Lemon Royale shows up in flower and pre-rolls as well as concentrates and vapes, and those products differ a lot in strength, so check which one you're holding.
Read the THC and CBD numbers and the packaging date, since fresher flower keeps more of that sharp lemon smell.
Lemon Royale vs Lemon Tree
Lemon Tree is Lemon Royale's citrus parent, so the two share that sharp, fresh lemon smell. Lemon Tree pairs it with sour diesel and is usually listed at about 17% to 25% THC. Lemon Royale adds the funk and musk of GMO and Triangle Kush and tends to be listed stronger. Both get described as upbeat, though Lemon Royale's reviewers mention more body feel as it settles. If you want a cleaner lemon and fuel strain, start with Lemon Tree; if you like your lemon with some funk, try Lemon Royale.
