Enable an AI agent to recognise a Clematis plant, assess its seasonal condition and select care, propagation or containment actions appropriate to its identity and growing context.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a Clematis plant, assess its seasonal condition and select care, propagation or containment actions appropriate to its identity and growing context.
It can be Document diagnostic organs and qualify or revise a Clematis identification.; Train and secure shoots according to their observed attachment habit and available support.; Choose or defer pruning using flowering wood, seasonal phase and identity evidence.; Investigate decline and adjust growing conditions while tracking the plant's response.; Select a supported propagation method and preserve the relationship to the parent plant.; Assess fruiting and escaped seedlings before deciding whether to retain, relocate or contain growth..
Distinguishing features
Inspect several nodes for opposite leaves, often compound; combine this with reproductive evidence rather than identifying Clematis from leaf arrangement alone. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:329401-2/general-information)
For a climbing specimen, inspect whether leaf stalks or leaf axes wrap around supports, helping distinguish it from climbers using separate tendrils or attachment roots; absence of this behaviour does not exclude non-climbing Clematis. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:329401-2/general-information)
Examine floral organs for petal-like sepals rather than treating the showy parts as ordinary petals; record additional organs and compare with an appropriate species or cultivar description. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:329401-2/general-information)
Inspect mature fruit for a head of individual achenes with persistent styles, often elongated and feathery; this helps separate Clematis from climbers bearing berries or capsules, but a fluffy seed head alone is insufficient.

Characteristics
- Identity resolution
- Clematis suspected; genus confirmed; species supported; hybrid supported; cultivar supported; unresolved Determines how specifically care and reproductive behaviour can be inferred.
- Identity evidence
- Plant linked to dated observations, diagnostic references, accession records and supplier labels Separates a recorded name from an identification supported by evidence.
- Growth and attachment habit
- Leaf-stalk climbing; scrambling; trailing; erect non-climbing; unresolved Guides support selection and interpretation of unsupported stems.
- Plant extent
- Height, horizontal spread and selected shoot length in cm or m, with date Shows whether growth fits its support and whether intervention changes vigour.
- Seasonal phase
- Dormant; emerging; extending; budding; flowering; fruiting; senescing; mixed; uncertain Places leaf loss, shoot inactivity and care actions in seasonal context.
- Flower-bearing wood
- Previous-season shoots; current-season shoots; both; unobserved Helps predict whether cutting a stem would remove a flowering opportunity.
- Pruning-group assessment
- RHS group 1; group 2; group 3; unresolved, with evidence and regional context Connects identity and flowering observations to a justified pruning approach.
- Stem and crown viability
- Viable buds; active basal shoots; damaged stems; suspected dead tissue; confirmed dead tissue; uncertain Prevents failed top growth from being treated automatically as death of the whole plant.
- Root-zone moisture
- Volumetric water content in %, with depth, method, location and time Supports investigation of water stress without relying only on surface appearance.
- Collapse pattern
- Absent; isolated shoot; several shoots; whole canopy; recurring, with onset and associated symptoms Preserves evidence needed to investigate wilting before assigning a cause.
- Support relationship
- Plant linked to occupied support, attachment points, ties and neighbouring vegetation Makes training or removal possible without confusing intertwined plants.
- Reproductive establishment
- No fruit observed; developing fruit; mature fruit; seedlings suspected; seedlings confirmed Informs propagation and assessment of spread beyond the intended location.

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 22 questions.
Clematis identity Evidence that the plant belongs to Clematis and how narrowly it can be named.
Species and cultivar uncertainty can change care decisions even when the genus is recognisable.
Diagnostic organs
Joint interpretation of leaves, attachment structures, flowers and fruit.
Genus identification
Record observed diagnostic combinations, missing organs and competing identifications.
- Which leaf, attachment, flower and fruit observations jointly support Clematis? definition
- Which locally plausible lookalike remains possible, and what observation would separate it? boundary
Species and cultivar
Resolution of botanical names, hybrid attribution and horticultural labels.
Name confidence
Keep label claims distinct from independently supported identity.
- Where did the species or cultivar name originate, and what evidence corroborates it? provenance
- Which decisions require a narrower identification than the evidence currently supports? action
Shoots and support The plant's physical extent, attachment behaviour and continuity through tangled growth.
A useful intervention must target the right Clematis stems and accommodate how this plant holds itself up.
Stem continuity
Trace shoots to their base and distinguish live structure from entangled neighbours.
Plant boundary
Establish which stems and basal shoots belong to the individual being assessed.
- Can each proposed pruning target be traced to this Clematis rather than a neighbouring climber? boundary
- What are the current height, spread and locations of viable buds and basal shoots? measurement
Attachment and training
Fit between observed growth habit and the occupied support.
Support fit
Record successful attachment, unsupported extensions and damaging ties or contact points.
- Which support elements can this plant actually grasp, and where do shoots remain unsupported? measurement
- Which shoots can be redirected or secured without breaking stems or constricting growth? action
Flowering and pruning Flowering chronology and shoot age as evidence for pruning decisions; RHS distinguishes three groups using flowering time and flowering wood. [RHS pruning guide](https://www.rhs.org.uk/plants/clematis/pruning-guide)
A generic seasonal pruning instruction cannot represent the differences among Clematis flowering patterns.
Flowering evidence
Dated observations connecting flower flushes to identifiable shoot generations.
Flowering wood assessment
Support or withhold a pruning-group assignment using identity and observed flowering.
- When did each flowering flush occur locally, and did it arise on previous-season or current-season shoots? measurement
- What reference or observation supports the proposed pruning group, and does any evidence conflict? provenance
Pruning decision
Translate flowering evidence and plant condition into a specific intervention.
Cut selection
Identify the purpose, timing, retained buds and expected flowering consequences of proposed cuts.
- Is the intended operation establishment pruning, routine pruning, removal of damaged stems or renovation? action
- Which stems and buds would remain, and what flowering would probably be lost or deferred? action
- If flowering behaviour is unresolved, what observation should precede substantial pruning? action
Root zone and decline Growing conditions, symptom patterns and recovery evidence.
Wilting must be investigated in context rather than converted directly into a diagnosis of Clematis wilt.
Growing context
Conditions experienced by the roots and canopy of this particular plant.
Site fit
Compare measured conditions with requirements supported for the identified Clematis.
- What are the root-zone moisture, drainage behaviour, canopy light exposure and recent temperature extremes? measurement
- Which requirements are verified for this species or cultivar, and which remain assumptions? provenance
Collapse and recovery
Distinguish observed symptoms from their proposed causes; Clematis wilt is one possible explanation requiring supporting evidence. [RHS Clematis wilt guide](https://www.rhs.org.uk/disease/clematis-wilt)
Decline assessment
Record onset, affected organs, stem injuries, root-zone conditions and surviving growth before selecting a response.
- Which shoots collapsed, how quickly, and what discoloration, lesions, breakage or basal regrowth accompanies them? measurement
- What evidence separates water stress, mechanical injury, seasonal dieback and a possible disease process? boundary
- Which intervention and follow-up observation would test the leading explanation while preserving viable growth? action
Propagation and spread Reproductive material, parentage and establishment outside the intended planting.
Producing another plant, preserving a named cultivar and allowing local spread are different decisions.
Propagation intent
Match the desired offspring identity to a supported propagation method.
Offspring identity
Record parent material, method and the evidence needed before assigning the parent's cultivar name to offspring.
- Is the objective to preserve a named cultivar, multiply an identified species or raise variable seedlings? definition
- Which propagation method is supported for this Clematis, and how will parentage and identity be retained? action
Establishment beyond planting
Observed recruitment and location-specific evidence relevant to retaining or containing the plant.
Spread decision
Separate seedlings, connected growth and unrelated plants before assessing spread; attach regional conclusions to an identified taxon.
- Are plants beyond the intended boundary independent seedlings, connected stems or a different species? boundary
- What current local evidence about this taxon supports allowing seed set, removing recruits or seeking a containment decision? action
What the second pass must settle
- Does vr.tr.clematis denote the whole botanical genus, including non-climbing forms and horticultural hybrids, or a narrower intended concept?
- Which regional identification keys and cultivar records adequately cover lookalikes and ambiguous nursery labels?
- How should pruning-group confidence and exceptions be represented when identity is uncertain or flowering differs across climates?
- Which species- or cultivar-specific thresholds for moisture, temperature and establishment are sufficiently supported to guide intervention?
- Which taxa and locations require additional evidence about spread, conservation restrictions or handling hazards before propagation, relocation or removal?
