Lexicons are fertilizer for new fields of inquiry. New ways of doing require new ways of perceiving and conceiving. This project → Explores the overlaps of plant and machine intelligence → Gathers insights from anthropologists, philosophers, ethologists, and plant neurobiologists → Envisions ways of life aligned to earth's ceaseless metabolism → Moves away from exclusively human-centred concerns on the composition of worlds
It consists of terms drawn from a range of research fields. Users and co-conspirators are encouraged to submit signals to our research repository on Are.na, or reach out to us with thoughts.
Fertilizer is a research platform for future activations. The terms are meant to generate further projects across design, art, science, engineering, and more.
Humans have never been the only planetary intelligence. While we are building planetary-scale systems of computation and calculation that exhibit certain kinds of intelligence — ones that can effectively mimic human modes of writing, visually identify objects with higher degrees of accuracy than their human counterparts, and beat humans in domain-constrained games with inhumanly beautiful styles of play – what we call the natural world is already filled with complex forms of communication, processing, creativity, and intelligence.
Animals, from vertebrates to invertebrates, corvids to cephalopods, each demonstrate forms of intelligence tightly linking what they sense to how they interact with their environments. Plants, too, sense, process, and signal. But more so than animals, their worlds are utterly foreign to ours. They are sessile (immobile), autotrophic (producing their own food), and perpetually morphogenetic (never stopping their growth). Of course, for each of those rules, an exception in the plant kingdom can be found.
It is these very characteristics that make them important for imagining other worlds, in which the mutual entanglement of plant and machine intelligence can be a source of inspiration, a modality for extended and remote sensing, a field for modelling and simulation, and a domain for mutual actuation.
Exploring these entanglements is not about communicating with plants, controlling them, or projecting our aspirations onto them. It’s about interfacing with their already complex forms of phytosemiosis, and cultivating an art of noticing their strangeness – a strangeness that is just as foreign as our own cultivation of machine intelligence, and just as strange as our own perpetually redefined humanity.

An ancient form of food production and agroforestry system (100,000–10,000 BCE) that produces fruits, nuts, herbs, vines, and vegetables, archaeological evidence of which points to areas like the Amazon as once being a massive experiment in forest gardening.
Attempt by Georges Bataille (1949) to turn economics away from a foundation in scarcity towards one in abundance and excess – from the sun, whose excess energy and waste is the foundation for photosynthesis and life, to human societies, which waste in war and entertainment, excess rather than scarcity is key to understanding economies of circulation.
The Great Silence
The phenomenon of not finding any signs of other life or intelligence in the universe, also known as the Fermi paradox (1950s), allegorized by sci-fi writer Ted Chiang (2016) to ask why, even on this Earth, we’ve barely recognized the existence of other intelligent species.

Horizontal Gene Transfer (HGT)
Contrary to the notion that genes can only flow down from parents to offspring, much of evolutionary history has consisted of sideways exchanges of genes across species and kingdom boundaries; this form of natural genetic engineering has prompted molecular biologist W. Ford Doolittle (2000) to question the very notion of a "tree" of life, with its clean notions of descent.

Neish (1965) has suggested that phenolic compounds toxic to plants are polymerized and stored in cell walls and vacuoles, essentially storing waste internally as a building material.
Academic field of study established in 2005 to explore parallels between plant physiology and neural networks in animals; extends back to Darwin’s "root-brain hypothesis," (1880) and Democritus’ description of plants as "upside-down humans" (400 BCE).
The unproven theory by Gottlieb Haberlandt (1905) that plants have epidermal cells that function as real lenses (known as ocelli, common in invertebrates), transmitting visual information not only about light but shape and movement; could explain the mimicry capabilities of certain plants that have no other known mechanisms for copying their neighbours.

An unnamed sense of isolation and sadness that stems from disconnection with other species and forms of kin (2015), demonstrated by the inability of many North Americans to identify even a handful of flora in their immediate environments (2018).
Speculative Time Complex
Recursive feedback between a model and the reality it represents, as exemplified in financial models which don’t neutrally represent future-states, but play a role in causing them to emerge; concept expanded by Armen Avanessian and Suhail Malik (2016) to ask whether recursive tools could be harnessed by other models to manifest other futures, such as with climate change.
A mechanism (1959) for coordinating the behaviour of individual agents, without centralized control, by communicating through traces and changes to the environment, often studied in the context of insect swarms but equally as applicable to plant roots as to organizational design (2006).

There are as many ways to use the lexicon as there are combinations of terms within them. Here, we highlight three ways they could function:
1/ This lexicon is an ongoing project to develop a new vocabulary at the intersection of plant and machine intelligence. It is oriented towards design in an expanded sense of the term, including the activity of scientists, engineers, writers, strategists, and artists. It draws from a range of fields – from plant neurobiology to speculative design, artificial intelligence to geomorphology, media theory to ecological economics.
From these fields it extracts a range of terms. Some of the terms are concepts, some describe processes, while others are simply singular things. This heterogeneity of terms – in the fields they come from and the forms they take – is important. A lexicon is arranged arbitrarily, in the sense of alphabetically. Terms that have no relation to one another in field or form can suddenly find themselves in proximity, in communication.
Combining disparate terms can allow for the construction of new diagrams – one could, for instance, draw a circuit between an unrelated concept and a process to generate a new speculative entity. Or combine an entity and a process to incubate a new concept. In that sense, the lexicon is a machine for speculative diagramming. A tool to imagine new worlds.
2/ The terms operate at various scales. Some are geographic – certain terms apply globally while others are resolutely local; some operate on an infraindividual scale while others accelerate and spread rapidly across the transindividual.
Other scales are temporal – some terms rise from the histories of deep time in the first glimmers of life itself, while others exist in a not-yet-actualized future that is nevertheless retroactively shaping the present; some have operated for thousands of years, while others will flash into and out of existence, never to re-emerge.
As media and design theorist Benjamin Bratton has described, these two axes, of temporal and geographic scales – long and short timescales, large and small spatial scales – outline a matrix for speculative design. Placed perpendicularly, the two axes create four quadrants, none of which is necessarily more significant than the others. A global intervention spanning centuries might not be any more transformative than a completely localized and momentary one. But neither is a localized, momentary intervention to be lauded as inherently more progressive than a durable global one.
In that sense, the lexicon is an ethico-aesthetic bridge across scales. A way to build alliances across a multiplicity of interventions and modalities.
3/ When the word "individual" is used, it isn't meant in the sense of a human individual, or not only. The commonsensical notion of an individual as a singular human is not enough. There are many kinds of individuals.
An individual is any consistency of heterogeneous parts held over time, as elaborated by philosopher Manuel DeLanda. It’s an assemblage, its borders porous in space and time. One could speak of a society as an individual, a pack of animals as an individual, or a tree that reiterates endless copies of itself on its trunk as an individual. What matters is the consistency held by the parts over time, which produces a whole greater than the parts.
This matters because culture has over-indexed on human-centredness. It has targeted a reduced, abstracted, isolated notion of an individual as a single human being. In so doing, it has achieved tremendous effectiveness in some metrics – in intuitiveness, in convenience, in impulsivity. But in doing so, it has helped enable a range of unaccounted externalities, including environmental, social, and psychological damages. It has failed to adopt the flexible scales and complex understandings required to address 21st-century problems.
In that sense, the lexicon is an opening to what lies beyond human-centredness. It is a call to take seriously the strangeness of other intelligences and needs, and to begin thinking about the design of more-than-human futures.
Notes on sensing
We’ve fantasized about machines becoming intelligent for thousands of years. Some of the earliest written traces document this, like Homer’s description of Hephaestus, the Greek god of invention, living luxuriously in his proto-smart home – with its automated gates and forges, driverless delivery bots, autonomous servants, and machine-generated music. Meanwhile, plants have been variously denigrated and ignored, relegated to an invisible background condition, a lower rung on the pyramid of life – alive but not sentient, and certainly not intelligent.
Plants were forgotten even on the venerable Noah’s Ark. Had Noah's program to restore the globe’s ecology been carried out as designed, it would have resulted in a rather temporary repopulation, as an increasingly putrid mass of animal flesh fought for the rapidly diminishing scraps of the last negentropic stores of energy – each others’ bodies. Lacking the autotrophic ability of plants to transform solar energy into chemical energy, all animal life would vanish from the world after a short but intensely non-aromatic carnival of negative-sum calorie depreciation.
Of course, this plant-blindness has not been constant across all places and times. Various cultures, practices, and knowledges have given more or less weight to the agential capacity of plants. Most recently, the modern scientific tradition has itself – not without controversy – begun to reverse its view of a mute botanous universe. It has seen the inauguration of fields like plant neurobiology, which studies the parallels between the neuronal structures of animals and the root systems of plants, a parallel noted by none other than Darwin himself.
Plants, like all living things, must be able to sense, process, and respond to a changing environment if they wish to survive. The extent and fury of this semiotic exchange has been underestimated until recently. In fact, it could turn out that life and semiosis emerge at the same time and for the same reasons – any living thing must be able to process signs from its environment. The mechanisms by which even the "dumbest" of simple cells sense and process information remain barely catalogued, while the scope of both knowns and known unknowns in their functioning steadily grows.
As our awareness of the scope of life’s capacity to communicate within and between individuals continues to grow, we should stop to note that what’s being described are forms of non-linguistic communication. There is no "language" of plants, nor any interest in resurrecting dubious metaphors extending language everywhere. But there is an exchange of signs of various kinds – indexes pointing to states and changes in the environment and icons mirroring them topographically. Plants' most robust sensing is chemical, but they also have multiple photoreceptors, the ability to sense touch, gravity, humidity, and proprioception. Plants process and respond to these signs in complex ways, producing emergent intelligences that can’t be reduced to mute matter any more than humans’ own use of signs elsewhere on the semiotic continuum.
Plants' evolved forms of intelligence – of sensing and responding non-deterministically to their environments – only make sense if we step out of our human and zoocentric perspectives. Able to generate chemical energy from solar capture, they have evolved body plans to maximize surface area but make mobility impractical. Their sessility – rootedness in fixed location – exposes them to the predation of mobile creatures, generating a range of creative adaptations, including the production of an endless array of pharmacological compounds to manipulate animals, impressive forms of mimicry and camouflage, the distribution of organs and functions throughout the body, various forms of natural genetic engineering, and the creation of symbiotic alliances with pollinators (such as birds and bees), defenders (such as ants), and network managers (such as fungi).
While none of these evolutionary inheritances is the result of plant intelligence, they set the context for understanding the Umwelt – the perceptual worlds experienced by an organism – of plant life. With a different set of defences, sources of energy, and bodily plans, the sensory arrangements of plants are geared towards entirely different ends than mobile creatures. Just because their intelligence doesn’t mirror our own doesn’t mean theirs doesn't exist, nor does it mean we have to jettison the only terms and metaphors – based on our own bodily forms and needs – that we have to make sense of them.
A metaphor can be a bridge taking us to a new form of understanding. The provocation to take plant intelligence seriously alerts us to the complexity of their behaviour, but only if we don’t project our own measures and modes onto them.
It is, in that sense, the same problem confronting us when we think about machine intelligence. If we don’t want innovation to be boring rehashes of ancient smart home fantasies, might we adopt a lesson from the resolute strangeness and alterity of plant intelligence when trying to conceptualize machine intelligence? Instead of androids in human form serving masters, shouldn’t we begin from the premise that how and what a system senses will set the foundation for what its intelligence could even be? Why is the human the only measure? Doesn’t this blind us to the ways machine intelligence is already here, in many of our daily interactions? Doesn’t this blind us to what it could become?
