The Breeder Behind Some of the Best CBD Flower on the Planet
There are breeders in the CBD world who do good work. There are breeders who do great work. And then there is Thomas Swanson at High Alpine Genetics - a man operating on a completely different level to almost everyone else in the game right now.
If you've ever opened a jar of our Rainbow Sherbet, our Fabled, our Yak Butter, our Applesauce or our Puff Pastries - you've experienced what we're talking about. The chances are, at some point, you've held a bud in your hand that exists because of this man's work. He's that embedded in what we do and why we do it.
This is our attempt to give him the recognition he deserves.
Who Is Thomas Swanson?
Thomas Swanson graduated with degrees in Crop Science, Viticulture and Wine Making from Cal Poly, San Luis Obispo, California. That background in viticulture - the science of growing grapes for wine - is actually really telling. Wine is one of the few industries that obsesses over terroir, genetics and the relationship between plant and environment the way serious CBD growers do. Thomas brought that same obsession to hemp.
Based in Glenwood Springs, Colorado, High Alpine Genetics is a family-run operation. Thomas serves as COO and is certified as a Colorado Department of Agriculture Seed Farmer - meaning this isn't a hobbyist project or a marketing exercise. It's a properly credentialed, professionally run genetics company built on deep knowledge of the plant.
The location matters too. The altitude and climate of the Colorado Rockies isn't just a nice backdrop - it genuinely shapes how plants grow. Stress at altitude produces trichomes. Clean mountain air and organic growing practices produce flavour. Thomas understood this from day one and built his entire operation around it.
What Makes HAG Different
A lot of CBD breeders are chasing numbers - CBD percentage on a COA, yield per plant, whatever makes the product sheet look impressive. Thomas has always chased something different. He chases flavour, terpene complexity and the kind of genetic consistency that means a Rainbow Sherbet grown in Oregon smells and tastes like a Rainbow Sherbet is supposed to.
The naming tells you something about the mindset. Rainbow Sherbet. Pineapple Sugar Cookies. Yak Butter. Applesauce. Lemon Fritter. Orange Glaze. These aren't random - they're sensory promises. Names that describe exactly what you're going to experience when you open the jar. That kind of confidence in your product comes from knowing your genetics inside out.
The breeding methodology at HAG is rooted in patience and selection. Strains like Fabled were pheno-hunted specifically for dense bud structure and a terpene profile dominated by cream, cookie dough and sour gas. That level of specificity - hunting individual phenotypes within a cross for very particular characteristics - is the difference between a good breeder and a great one. It takes time, it takes space, it takes the willingness to throw away a lot of plants that aren't quite right in pursuit of the one that is.
Everything stays within legal THC limits throughout all of this - but without ever sacrificing the qualities that make the flower worth growing in the first place. That balance is harder to achieve than it sounds and Thomas has been doing it consistently for years.
The Strains That Put HAG on the Map
If you want to understand the breadth of what Thomas has created, just look at the range.
Rainbow Sherbet is a sativa-dominant hybrid crossing Fruity Pebbles OG and Blood Orange Diesel - delivering that signature fruity sweetness with a gassy, fuel-driven back-note that CBD heads have gone absolutely mad for. It's one of the most talked-about CBD strains in the US, and the UK right now - and for good reason.
Yak Butter sits at the opposite end of the spectrum - creamy, skunky and deeply Indica in character. Applesauce is one of those strains that makes you question how a plant can taste that good. Fabled became a benchmark for what premium Indoor CBD flower could be. And Puff Pastries - a cross of Payton's Lemons 1 and Fruity Pebbles OG, with real Cookie family provenance running through the genetics - is as indulgent as the name suggests. Sweet cream and lemon zest upfront, with tropical fruit and warm doughy pastry notes coming through as the flavour opens up.. Every single one is a complete, considered piece of work - not a quick cross thrown at the market but a properly developed, selected and stabilised strain with a consistent identity.
And the influence doesn't stop at his own catalogue. HAG's seeds are distributed to growers across the US and beyond - meaning the fingerprints of his genetics are on flower being grown across Oregon, Colorado, California and further afield. When you buy premium US sungrown CBD flower from anyone serious about quality, there's a decent chance Thomas had something to do with it at some point in the chain.
Why It Matters to Us
We get asked sometimes why we're so specific about genetics. Why it matters who bred the seed, not just who grew the flower. This is why.
Genetics is everything. The best cultivator in the world growing mediocre genetics will produce mediocre flower. But put a great cultivator in the Rogue Valley, Oregon with a properly developed HAG strain and what comes out the other end is something like our Rainbow Sherbet - a flower that our community reviewer Benzil described as some of the most beautiful outdoor flower he'd ever seen, one that could easily be mistaken for indoor. That's not just a growing story. That's a genetics story.
We don't have a direct relationship with Thomas - we source from the farmers who grow his genetics, not from HAG directly. But we watch what he does with enormous respect and genuine excitement. Every time something new comes out of that Colorado operation we're straight on it, hoping we can get our hands on whatever the farmers we work with are growing from his latest work.
If you've ever wondered why the flower from Originals hits differently to what you've tried elsewhere - a big part of that answer starts with breeders like Thomas Swanson.
Not many people can genuinely claim to have changed an industry. Thomas Swanson is one of them. A pioneer, a craftsman and a living legend in the CBD genetics world - and the reason so many of the jars we open at Originals smell and taste the way they do. The work speaks for itself. Thank you Thomas.
