Where It Begins: The 2026 Mother Plants

Every season starts with a decision.

Not every flower is used. Not every plant is worth continuing.
Before a single seed is sown, the direction of the next generation is set here.

These are some of the mother plants selected during the 2025 season — the crosses have been made, and the seeds are now set for sowing in 2026.
Each was chosen for specific traits, consistency, and potential. Some are obvious. Others are quieter, selected for what they might become rather than what they show now.

What follows is a behind-the-scenes look at the earliest stage of a new season of hybrids.

For a closer look at how this work plays out in practice, see Lobivia in Bloom: Behind the Scenes at Spine City.


Experimental Lines

Early-stage selections, long-held plants, and exploratory directions. These are included for potential — not certainty — and often represent new traits or ideas being pushed into the program.

What you’re seeing here becomes the starting point. What follows is where most of it disappears — see The Cut: How We Select Lobivia Seedlings at Spine City.



Lobivia larae flower with saturated red tones and strong structure, large-bodied cactus bloom at Spine City

18.109.1
A wild card selection chosen for its saturated colour, sharp structure, and overall impact. The unusually large body opens two directions — reducing size to amplify the flower, or pushing for increased bloom size through hybridising.
Long grown but previously unused, now brought into focus.

Lobivia scheerii flower with deep mango-orange tones and sharp, pointed petals at Spine City
18.111.1
Defined by sharp, whorled petals and a deep mango tone. Previously overlooked in earlier hybridising work, now brought forward on the strength of its foundation flower. Potential is high, direction still open.

Lobivia tiegeliana × xanthinantha flower with cupped, stacked petals and dusky pink to buttercup yellow transition at Spine City
18.118A
A long-watched selection now brought into the program. Features a cupped, stacked form with a transition from dusky pink outer petals to a rich buttercup yellow centre.
The tight, compact body aligns with the direction — smaller plants with high-impact flowers. Focused on how both form and scale carry through hybridising.
Lobivia westii flower with saturated orange and red tones, sharp petals and condensed yellow centre at Spine City
18.119.1
High energy, high impact. Saturated orange brushed with red, anchored by a condensed yellow centre. Chosen for its sharp shape and structure, with a focus on how that form carries through hybridising. Backed by a firecracker, ember-toned palette.

Lobivia caniana flower with dense, stacked petals and textured pink and white tones at Spine City
19.200C
An experimental inclusion based on Lobivia caniana, one of the more difficult plants to grow. A key focus here is whether hybridising can reduce that difficulty and introduce some level of hybrid vigour. The flower itself is dense and stacked, with irregular, highly textured petals brushed in pink and white.
A line with serious potential, pushing beyond what’s been seen so far.

Lobivia drijveriana flower with intense fire-red colour and saturated petals at Spine City
19.205.2
A fire-engine red, highly saturated selection. Red is notoriously unpredictable in cactus flowers — what you see rarely translates directly, which makes it a strong focus for exploration.
This one sits high on the radar.

Lobivia wegheiana flower with fine petal detail, subtle tones and compact form at Spine City
19.223.4
Selected for micro-detail rather than overall impact. Smaller flowers, but rich in nuanced traits that warrant deeper exploration. Focused on drawing those details forward and compounding them over successive generations.
A longer-term project, with results expected to emerge over time.

Lobivia wrightiana flower with tattered, brush-stroked petals and distinctive form at Spine City
19.225A
A no-brainer inclusion run aggressively across seasons. Stands apart from its siblings with a distinctly different body, paired with a tattered, brush-stroked flower. Selected for its unpredictability and the potential to produce standout results when introduced into the hybrid mix.

Lobivia backebergii flower with soft pink cupped petals and rounded form at Spine City
20.220.5
Chosen on instinct — a compact, cupped flower with a soft, rounded form and clean pink tone. Simple, balanced, and immediately appealing.
Included for its natural charm and potential to translate that ease into future generations.

Lobivia jajoiana cv. Anemone Pink flower with dark centre and layered pink petals showing strong colour transitions at Spine City
20.223.7
An existing hybrid grown from seed, continuing on from prior work rather than starting from a pure species. Features a dark centre with strong colour transitions and petal accents. With unknown genetic background, this line is driven by discovery — a long-term exploration of how it unfolds across future generations.

Lobivia jajoiana cv. Anemone White flower with clean white centre, chartreuse glow and soft dusky pink outer petals at Spine City

20.223.29
From the same seed batch as 20.223.7, but markedly different in expression and a standout within the line. Features a clean white centre with a chartreuse glow, framed by soft, dusky pink outer petals. Continuing from an existing hybrid line, this selection is driven by its standout flower, with translation into future generations still to be seen.


Lobivia hybrid 22.258.3 flower with distinctive form and unique colour expression from an F2 line at Spine City
22.258.3
A true rogue from an F2 line. Shows a strong departure from the mother plant — to the point where the relationship isn’t immediately obvious. Selected to explore that divergence and uncover what else sits behind the genetics.

Foundation & Ongoing Lines

Established plants and repeat performers that continue to anchor the program.


Lobivia winteriana flower with vibrant tones and variable petal form, a foundation hybrid line at Spine City
18.120.2
A core foundation line used consistently across seasons. Delivers high-quality, highly variable flowers rather than repeatable outcomes.
A proven performer and permanent fixture in the hybrid program.


Lobivia rebutioides var. krausiana flower with vibrant tones and compact, layered petal form at Spine City

19.211.1
A long-worked line with a degree of unpredictability. Can produce less impressive blooms, but also has the ability to deliver standout results. Selected for that upside, with a focus on filtering for the best outcomes through successive generations.


Second & Third Generation Work (F2 / F3 Progression)

Lines being actively pushed forward through successive generations.



Lobivia hybrid 20.85.4 flower with sharp, angular petals and intense orange tones at Spine City
20.85.4
A second-generation push from a Spine City F1 line. Sharp, almost aggressive in form, with a pungent orange tone and darker accents. Selected for its strength and intensity, with a focus on how that expression evolves — whether it amplifies further or softens in future generations.

Lobivia hybrid 20.85.45 flower with soft colour transitions and smooth petal gradation at Spine City
20.85.45
An F1 line initiated at Spine City, pulled from production and moved directly into the hybrid program. Selected for its early foundation in colour transition and gradation — not yet market-ready, but aligned with a clear direction focused on colour flow and petal storytelling.

Lobivia hybrid 20.85.53 flower with geometric petal shape and strong colour gradient at Spine City
20.85.53
An experimental F1 now being pushed into F2 and F3 work. Stood out early for its geometric petal form and strong colour gradient. Not a market piece in its current state, but a clear foundation for a new direction.
Notably produces longer flower stems, opening a distinct path within the hybrid program.

Lobivia hybrid 21.282.1 flower with strong colour gradient in orange, red and yellow tones and sharp petal form at Spine City

21.282.1
A line well represented in the 1-Code collection, with this selection held back for further hybridising. Carries a strong gradient through orange, red, and yellow into dusky outer tones, with a sharp, almost aggressive presentation. Selected to push further — to uncover what’s sitting behind it and amplify those traits in future generations.

Lobivia hybrid 21.341.1 flower with sharp, stacked petals and bold orange tones with reddish-pink striping at Spine City

21.341.1
An experimental F1 selected for its sharp, stacked petal form and bold orange base with a reddish-pink stripe. Presents a strong, angular, almost confrontational display.
Now being pushed into F2 and F3 work to uncover what else sits behind the line.


Lobivia 300

Lobivia 300 could easily stand on its own as a full post. It’s one of the largest and most heavily worked lines in the Spine City program, and a major source of direction across multiple seasons.

This is a foundation line — one that features heavily in One Plant, One Code – Our Lobivia Legacy, particularly behind many of the larger, more expressive blooms. Its predecessors have been pushed hard, selected from aggressively, and refined over time.

For the sake of this post, we’re pulling out a selection of standouts from the most recent season — including unreleased hybrids and plants held back for further work. For a deeper look into this line and its named cultivars, see The 300 Collection.



Lobivia hybrid 21.303.3 flower with deep blood-red tones fading to pink and scalloped layered petals at Spine City

21.303.3
Deeply saturated, almost blood red, fading out to pink in a strong 300-line gradient. Features scalloped petals and a bold, layered presentation. True to the line — unpredictable yet reliable — and firmly selected for further work.

Lobivia hybrid 21.303.7 flower with open, blousy pink petals and a free-flowing form at Spine City

21.303.7
A more open, less dense expression within the 300 line. Carries a strong pink tone, presented in a freer, more blousy form.
Selected to push the line toward a more open, free-flowing flower structure.

Lobivia hybrid 21.303.13 flower with hyper pink petals and green-accented outer edges at Spine City

21.303.13
A hyper pink bloom framed by green-accented outer petals — a rare and striking combination. Selected to push that green further into the flower and build a stronger pink-and-green expression across future generations.

Lobivia hybrid 21.303.16 flower with buttercup yellow petals, dark centre and textured form at Spine City

21.303.16
A rare yellow selection within the program, chosen for its buttercup tone, petal texture, and overall form. Features a defined dark centre and clean structure. An experimental venture focused on how the yellow translates within the line. 

Lobivia hybrid 21.303.20 flower with pastel peach tones, open fan-shaped petals and chartreuse glow centre at Spine City

21.303.20

A later expression from the 300 line, introducing a new pastel peach palette not seen in earlier generations. Features soft accents, an open, fan-like presentation, and a consistent chartreuse glow centre that lifts the overall colour.

Lobivia hybrid 21.312.30 flower with mango-orange tones, symmetrical dense petal form and chartreuse glow centre at Spine City

21.312.30
A newer mango-orange expression within the 300 line. Selected for its symmetry and the way the petals fold into a dense, fan-cup form.
Carries the consistent chartreuse glow centre.

Lobivia hybrid 21.317.1 flower with hyper pink colour and candy-peach stripe, dense stacked petals at Spine City
21.317.1
Hyper pink with a candy-peach stripe, delivered in a dense, sharply stacked form.
Super saturated, highly vibrant, and a clear standout from thousands of seedlings.


527 Collection

The 527 Collection represents a broad and actively evolving genetic pool. These are mixed hybrids originally grown from seed, now being pushed aggressively through the program.

Several early generations have already been completed, and while results from that work are still unfolding, the strength of the foundation has driven continued investment.
This is a line being advanced with intent — not reaction.

The 527 collection is built almost exclusively around small-bodied plants with high-impact blooms — a core focus of our hybrid work: smaller-growing plants with absolute knockout blooms.

Given the scale of the pool, not everything is shown here. What follows is a selection of standouts and key directions currently being pursued within the 527 line.



Lobivia hybrid 21.527.3 flower with hyper pink tones, extreme petal stacking and deep red centre at Spine City
21.527.3
Hyper-pink and highly saturated, with an extreme level of petal stacking — row after row building a dense, layered form. Carries a deep, almost blood-red centre fading out to pink, with a gradient that’s difficult to capture. Selected for both intensity and structure.

Lobivia hybrid 21.527.5 flower with soft white petals brushed with baby pink and clean, balanced form at Spine City
21.527.5
A softer selection focused on form over intensity. Clean, well-structured petals in white, lightly brushed with baby pink from the centre outward. Included to broaden the program — introducing a quieter, more refined expression alongside higher-saturation lines.


Lobivia hybrid 21.527.9 flower with mottled petal patterning, subtle tones and clean form at Spine City

21.527.9
Selected primarily for the mottled patterning within the petals. Carries a clean shape, though colour is secondary to its potential.
A forward-focused inclusion, aimed at developing and amplifying this trait over time.

Lobivia hybrid 21.527.15 flower with unique form and striking presentation, standout cactus bloom at Spine City

21.527.15
A clear standout. Exceptionally unique in form and presentation, requiring no justification for selection. Chosen to be pushed through hybridising and propagation, with the goal of expanding and carrying this expression forward.

Lobivia hybrid 21.527.22 flower with intricate colour gradient, detailed patterning and compact bloom at Spine City

21.527.22
Small in size but high in impact. Selected for its colour story, patterning, and gradient. Produces limited seed, so outcomes remain uncertain — but will continue to be pushed until results suggest otherwise.

Lobivia hybrid 21.527.46 flower with rich colour saturation, clean form and vigorous growth at Spine City

21.527.46
A proven selection that has already met all criteria for propagation and will be released in its current form. High-quality flower with strong colour and saturation, paired with a vigorous plant.
Still being pushed through the hybrid program to carry those traits forward.

Lobivia hybrid 21.527.47 flower with balanced structure, soft colour tones and clean presentation at Spine City

21.527.47
Selected for its overall structure and presentation. Carries a softer colour profile, balancing the more vibrant lines within the program. Aimed at exploring whether that softness holds or shifts toward greater intensity in future generations.



Of course, we can’t show everything in one post — the scale is simply too large. There are too many crosses, too many variations. For any one of the flowers shown here, there may have been a dozen or more others alongside it, each with its own path.

Intuition plays a large role. It always has. Alongside that, there’s experience — looking back at what has worked, what has carried, and what continues to hold. But there’s no illusion of control. What happens at the genetic level remains largely unknown.

And that’s the draw.

Hybridising sits somewhere between structure and imagination. It opens the door to possibility — to small tangents, quiet questions, and the unknown outcomes that follow. Each selection carries its own direction, but where it leads is never certain.

So the question becomes — what do you see in it?

What traits stand out? What colour stories feel like they could unfold? There’s no single answer. The possibilities are endless.

At certain points in the process, walking through the tunnels, there can be hundreds of flowers at once. It’s chaos — in the best sense of the word. But within that chaos, there’s a kind of clarity. A moment where something just aligns. This flower, that one — they belong together. Whether it works or not is another story entirely.

It’s that balance — chaos and clarity, sitting side by side — that makes the process what it is.

With that, we close out the 2025 crosses, and look ahead to sowing in 2026.
The flowers that follow… we may not see until 2028.
