A two-tier shelf fills the screen, with room for up to ten caudex plants. Rounded trunks, slightly tilted leaves and, occasionally, a crown divided in two. Released on October 13, the browser game Caudex Days is less about finishing a seedling quickly than watching seeds sown together refuse to become identical. Because this shelf has no soil to touch, waiting for germination, comparing roundness and deciding which pot to keep become unusually visible parts of the scene.
Sow four seeds and wait for difference
Four seeds can be sown in one pot. The official description gives a germination window of roughly six to thirty hours, and not every seed is guaranteed to emerge. After about three days, plants of the same species begin to differ in shape and roundness. These are game times, not real cultivation speeds. Yet the decision to preserve irregularity instead of erasing it as failure carries the attentive eye of a shop that works with seed-grown plants.
Konae, the company behind the game, specialises in small caudex plants raised from seed and uses LED shelving for its real stock. Caudex Days transfers that shelf to a phone and compresses the roughly two months it may take before species can be distinguished into about three days. The speed matters less than the small habit it creates: returning to the shelf and noticing what has changed.
The first four plants are Pachypodium gracilius, Adenia glauca, Ceraria pygmaea and Pachypodium windsorii. In the distributed interface image, one extends narrow leaves, another carries low branching, and a rare specimen divides into two heads. Before their names become familiar, the proportions between trunk and foliage can already be compared side by side.
Watering returns as wrinkles, not a formula
Watering is automatic at first. Later, its frequency can be set at one of five levels. Too little brings wrinkles to the trunk; too much damages the roots. This is not a shared care chart for four living species. Light, temperature, soil and season are absent, so the signals belong to the game. A real pot still asks for a decision based on its particular plant and environment.
Time continues after the browser is closed, and germination or a change in roundness can be checked later. Constant input is unnecessary; leaving and returning becomes part of play. A plant game therefore centres not on rapid tapping or instant completion, but on change that takes place while no one is watching. It gives the digital shelf an interval surprisingly close to a physical one.
Basic use is free, with a limit of ten pots. Players buy seeds and sell grown plants with an in-game currency that, according to the release, cannot be purchased with real money. Features for more than ten pots are still in preparation. The limit turns the shelf into a small act of editing: not only which plant scores highly for roundness, but which individual to keep and which to let go.
A specialist shelf becomes another entrance
Konae says it has delivered more than 420 plants across 45 of Japan’s prefectures during its first three years. That is the company’s own figure, but it locates the game within sustained observation rather than a sudden decorative idea. Experience in app development and the daily shelf of a specialist shop meet in the four seeds and the ten-pot limit.
There is also a tension in turning roundness into a score and a higher sale value. Rare double-headed plants appear as special variations. A living plant’s interest cannot be contained by one number, yet the system can provide an entrance to noticing difference. The useful distance is to resist carrying its score directly into the value of a real specimen, and instead ask why a particular outline held the eye.
A pot on screen cannot communicate the weight of soil or the temperature of a season. It does not replace growing a plant. Still, after seeing four germinations arrive at slightly different times and different forms gather on one shelf, the next real seedling may be viewed not only as a finished shape but through the time that led to it. The shelf of ten becomes a small place to practise waiting.
