Two Mutations: Freakshow and Australian Bastard Cannabis

Where fern-leaf and ABC came from and why a mutant autoflower is so hard to breed.

Almost all cannabis looks the same. The palmate leaf, the Christmas-tree silhouette you can pick out from across a field. That recognizability is a problem: what is easy to identify is easy to find. So one branch of breeding is busy not with yield or THC but with shape – with plants that don’t read as cannabis.

This piece is about two such mutations. They appeared in different parts of the world, decades apart. One in California, the other in the Australian bush. Both are now stabilized and moved onto autoflower – onto the very Lowryder platform that started the whole autoflower category in the first place. Here is how that happened.

The Fern That Wasn’t: Freakshow

On ordinary cannabis, the leaf is simply palmate: the blade spreads its “fingers” from a single point, like a hand. On Freakshow, a scatter of small leaflets sits along the central vein of each “finger” instead. The leaf becomes pinnate, dissected, closer to a fern than to cannabis. Same genome, same photosynthesis, the plant flowers normally – only the leaf architecture changes. The mutation isn’t unique to cannabis: the shift from a simple to a pinnate leaf is documented in other plants too, the tomato among them.

In our story, this trait was fixed by an American breeder under the alias Shapeshifter, seed bank Hi-Elevation Genetics – a California breeder who caught a rare mutation while working on a terpene profile and then refined it for years through selection and backcrosses. Freakshow is a cross of Pineapple Express (mother) and Holy Chiquita (father). Holy Chiquita, also known as Holy Banana, was bred by Coastal Seed Co. in Santa Cruz and is itself Big Sur Holy Weed x Banana Kush. Once the line was stable enough, the Humboldt Seed Company handled the large-scale seed increase; its public debut was at the Emerald Cup in 2019.

What matters more than the lineage is how the trait behaves. In the stabilized Freakshow line, the pinnate leaf shows up in most plants – the key difference from ABC below, which is recessive and segregates. By profile, Freakshow is a lively sativa: around 18-20% THC, pinene-dominant, with a pine-and-citrus aroma. The practical point is twofold. First, stealth and decorative value: a bush that doesn’t look like cannabis. Second – and this is rare for mutants – it stays a working strain: it grows, builds terpenes, and flowers like normal cannabis, not like a museum exhibit.

The Bastard from Down Under: ABC

Australian Bastard Cannabis (ABC) is a mutation from the opposite pole of strangeness and the opposite side of the planet. Its leaf is small, up to 5 cm, without the usual serration, smooth and glossy, more like parsley, boxwood, or a succulent than a cannabis fan leaf. The plant is low and dense, growing like a shrub rather than a Christmas tree. DNA analysis confirms it is Cannabis sativa – but the most distant relative within the genus, with the fewest shared genes even compared with industrial hemp.

ABC’s history is half-myth. By the cannabis community’s account, the plant was found in the countryside of southern Australia, in New South Wales, in the 1970s or 80s; locals called it Bindi Bud. In the 1990s, it was described and given the name “Australian Bastard Cannabis.” Among the rumors about its origin is a failed experiment with colchicine and polyploidy. What the practice confirms is the plant’s cold hardiness: it is phenomenally frost-resistant. Witnesses described bushes standing under wet snow with no frost damage while neighboring strains died.

For a breeder, ABC is a challenge, not a gift. The leaf trait is strongly recessive. Crossing pure ABC with a normal strain gives an F1 with normal leaves; the ABC leaf returns only in part of the F2 – around 25% in theory, 15-35% in practice because of modifier genes. On top of that, the original ABC was poor in cannabinoids. The sum of these two problems is why almost no commercial ABC strains have appeared over the decades: it is hard to hold the leaf and raise the quality at the same time.

For the lay of the land: fern-leaf and ABC are not the only leaf mutations. There is webbed/duckfoot (webbed leaf), variegation (two-tone leaf), and whorled phyllotaxis – three or more leaves from a single node instead of the usual pair. On a simple scale of practicality: stabilized Freakshow shows its leaf almost every time and stays a working strain, ABC is recessive and survives mostly as a genetic rarity, and the rest sit somewhere in between.

Two Recessives: Why a Mutant Autoflower Is Hard

On top of the leaf mutation comes a third trait, without which a modern strain can’t be built – autoflowering. And this is our home turf.

Lowryder, the strain that started the entire autoflower category, is Joint Doctor’s genetics – and Joint Doctor is the founder of Doctor’s Choice. In the late 1990s, working in a basement in the Canadian prairies, he crossed a “Mexican ruderalis” with Northern Lights #2 and William’s Wonder. Over generations of selection, a recessive trait surfaced: flowering by age, independent of the light cycle. That was the first commercial autoflower. Today, autoflowers are most of the seed market in Europe, and every autoflower on the shelf traces its lineage back to Lowryder. Hence our tagline: #Home of the Lowryder.

The keyword above is recessive. Autoflowering is recessive, ABC is recessive, and to a large extent so is fern-leaf. Crossing an autoflower with a photoperiod strain gives an F1 that flowers by light, not by age; autoflowering returns only in the F2 and beyond.

Hence the arithmetic of the task. To get an autoflowering mutant, you have to bring two recessive traits together in one plant, both homozygous – the leaf mutation and the autoflower trait. In a segregating population, such plants are a small fraction. In practice, that means not “cross it and you’re done” but “sow hundreds of seeds and keep a handful.”

The Work: Building the Lines

This was taken on by the independent breeder mutantfarmer – a participant in our Be a Breeder program. Work on the strains has been running since 2022, and the whole process – selections, crosses, harvests – was documented openly by the author on Instagram and on the ICMag and DZAGI forums. The logic was the same for both mutations: take a stable mutant mother and put her onto the Lowryder autoflower platform.

On the Freakshow side, the mother line was Freakshow genetics from 7East Genetics. On the ABC side, Drunken Bastard F3 from 7East Genetics – one of the few fully stabilized ABC lines, where every phenotype carries the trait. Drunken Bastard has exactly one drawback: it flowers for a very long time and won’t finish in a short northern summer. A cross with Lowryder solves both at once – it adds autoflowering and sharply shortens the cycle.

Then comes the honest price of a mutant autoflower. To pull the plants carrying both autoflowering and the mutation out of the segregating populations, mass sowing was required: 350+ seeds per line. The yield was exactly what you’d expect from double recessivity: autoflowering Bastards came out at under 5%, autoflowering Freaks at under 2%. From that handful, the best plants were selected and both lines taken to F5 – to the point where leaf shape, plant structure, aroma, and timing are predictable within an acceptable spread. The Bastard line was run in two parallel branches so as not to lose material through the narrow neck of selection.

In the next article, we’ll find out how both mutations ended up on our Lowryder platform in the Doctor’s Choice x mutantfarmer lineup.
