Module 5 — The Correspondence System: Elements, Planets, and Magical Properties

A witch could try to learn plant magic by memorizing each herb as an isolated fact — rosemary does this, lavender does that, basil does another thing, on and on through hundreds of plants. It would take a lifetime and produce shallow knowledge. The correspondence system exists because the older traditions found a smarter way: organize plants by the registers they belong to, learn the registers, and any plant becomes legible the moment a witch knows where it sits.

A correspondence is an association linking a plant to a broader category of meaning. A single plant corresponds across several systems at once. Rosemary, for example, is fire by element, Sun by planet, masculine by traditional gender (in systems that use that polarity), Tuesday or Sunday by day depending on the source, sometimes the solar plexus by chakra (in traditions that overlay chakras onto plants), red and gold by color, Aphrodite and the Virgin Mary by deity association — and that is before naming what it actually does operationally, which is protection, purification, memory, love, healing, exorcism. A witch who knows the correspondences can read all of those registers from a single plant in seconds. Without the system, she is left memorizing isolated facts forever.

The system the modern English-speaking witch uses is largely a synthesis of medieval and early modern European sources, refined and consolidated in the twentieth century. Heinrich Cornelius Agrippa's Three Books of Occult Philosophy in 1533 systematized the planetary correspondences across stones, plants, animals, deities, and metals. Nicholas Culpeper's Complete Herbal in 1653 assigned a planetary ruler to every common European herb in plain English, fixing those associations in the popular tradition. Twentieth-century writers — Scott Cunningham most influentially, in his Encyclopedia of Magical Herbs — consolidated Agrippa, Culpeper, folk tradition, and personal-intuitive material into the reference tables contemporary witches reach for. Some of what these tables contain is genuinely ancient and cross-cultural — red for blood and passion and fire is older than any of the named sources. Other parts are specifically Western, specifically post-medieval, and carry the worldview of the cunning folk and the Renaissance magicians who shaped them.

The elements come first. Four classical elements, four families of plants.

Earth

Earth plants are stable, grounding, often with strong roots, frequently woody or tuberous. They sit close to the ground in their growth habit and tend to age slowly. Patchouli, vetiver, oak, comfrey, and many of the deep roots fall here. (Mandrake is also classified as earth, though it belongs to the poison path conversation rather than to general practice.) Earth herbs are reached for in workings that need grounding, money, home blessing, manifestation in the material world, and a particular kind of patient, settled protection. A witch who has just finished a draining ritual, or who needs to come back into her body after a long inner working, reaches for an earth herb.

Water

Water plants tend to be flowering, often gently aromatic, often associated with the moon and with emotion. Rose, jasmine, chamomile, lavender (sometimes water, sometimes air, depending on the source), yarrow, and willow live here. Water herbs dominate the love and dream categories — almost any classical love working will draw heavily from water plants — and they carry emotional healing, divination, and psychic work. The herbs the witch reaches for when the work is on the heart or the inner planes are usually water.

Fire

Fire plants come pungent and sharp; warming when handled or tasted; with red, orange, or yellow flowers or fruits. Basil, cinnamon, bay, dragon's blood resin, ginger, black pepper, and the assertive Mediterranean herbs cluster here. Rosemary is sometimes classified as fire, sometimes as earth — sources disagree, and the witch picks one and stays consistent. Fire herbs do passion, courage, action, success, banishing, and the kind of purification that burns clean rather than washes clean.

Air

In the air register sit lighter, more aromatic plants tied to thought, communication, and movement. Lavender (in its other classification), mint, common sage, eucalyptus, lemongrass, anise, and dill belong to air. The work air herbs do is communication, mental clarity, study, travel, certain kinds of cleansing (the wind kind, the fresh kind), and some dream work where the dreams are clarity-focused rather than emotion-focused.

A plant can sit primarily in one element while carrying secondary tones from another. Lavender is the cleanest example — half the sources put it in air, half in water, and both are right. The witch holds the system loosely enough to read these blendings.

How to Read a Correspondence Entry

A typical entry in a magical herbal looks something like this:

Rosemary. Element: Fire. Planet: Sun. Magical Properties: Protection, purification, memory, love, healing, exorcism. Gender (in some traditions): Masculine. Deities: Aphrodite, Hebe, Virgin Mary.

Each field is a lens. Fire tells the witch rosemary is active and transformative — it does work that moves and burns through things rather than soothes. Sun tells her it shines on what it touches, supports vitality, success, recognition. The property list tells her what rosemary does operationally — these are the categories of working it shows up in across centuries of practice. The deity associations point her toward whose work rosemary can be connected to (Aphrodite for love workings, the Virgin Mary for protective and devotional ones in Christian-syncretic practice, Hebe for youth and renewal). Reading all the fields together is how the correspondence system becomes useful rather than overwhelming.

The Doctrine of Signatures

Worth naming because it is genuinely old and still useful. The doctrine of signatures held that a plant's appearance reveals its uses — that the green world is signed for those who can read. Heart-shaped leaves are for the heart. Red flowers for blood and passion. A root that looks like a human figure (mandrake) is for sympathetic human-shaped magic. A yellow flower for the sun. A plant that grows up through stone or breaks pavement for breaking blockages. A plant whose leaves grow back when cut for healing and resilience.

The doctrine is not reliable as botanical science — many plants violate their signatures, and many plants with no obvious signature are powerfully effective. But it is useful as a mnemonic, and it is sometimes startlingly accurate as intuition. The medieval herbalists who noticed that Hepatica leaves resemble the lobes of a liver were not wrong that the plant was used for liver complaints in folk practice. A witch learning plants partly through their signatures is using an old and respectable approach. She cross-checks against the correspondence tables, and over time she develops a feel for when a signature is telling her something true and when the resemblance is coincidence.

To read a plant by signature, the witch holds the plant — fresh if she has it, dried if not — and notices what it looks like, what it feels like in the hand, where it grew, what its growth habit suggests. A plant that climbs may want to be reached for in workings of advancement; a plant that runs along the ground may want grounding work; a plant whose flowers face the sun (sunflower, calendula) clearly belongs to solar magic. The signature is one more reading, not the only one — but for plants the witch has not yet built a relationship with, it gives her a place to start.

The Seven Classical Planets

The planetary system runs alongside the elements as the second major axis of correspondence. The seven classical planets each govern a register. Sun for success, vitality, and recognition. Moon for dreams, intuition, and the inner tides. Mercury for communication, mind, and travel. Venus for love, beauty, and harmony. Mars for courage, passion, and protection by force. Jupiter for expansion, prosperity, and luck. Saturn for boundaries, endings, and discipline.

Each planet's herbs cluster naturally: solar herbs (bay, calendula, chamomile, frankincense, rosemary, St. John's wort, sunflower), lunar herbs (jasmine, lotus, lemon balm, mugwort, night-blooming flowers), Mercury herbs (lavender, dill, mint, parsley, lemongrass), Venus herbs (rose, apple, burdock, yarrow, cardamom, thyme), Mars herbs (basil, dragon's blood, garlic, ginger, allspice, chili pepper), Jupiter herbs (common sage, hyssop, maple, dandelion, meadowsweet), and Saturn herbs (patchouli, comfrey, cypress, elder, yew).

When the witch's intention matches a planet's register, she reaches into that planet's cluster.

A plant has both an element and a planet. Reading them together is what makes a correspondence three-dimensional. Rose is Venus and water — love, in its emotional and flowing forms. Bay is Sun and fire — success, in its bright and active forms. Patchouli is Saturn and earth — slow material accumulation, money that stays. The combinations tell the witch what register the herb actually works in.

How to Match Herbs to Intentions

This is where the system pays back the time spent learning it. The witch starts with her intention and works backward to the plants.

She names what she wants. I need courage for a hard conversation tomorrow. Courage is Mars, and the elemental register is fire. She looks at her cabinet for fire-Mars herbs. Cinnamon, ginger, basil, allspice, black pepper — all fit. She blends what she has into a small sachet to carry, or a tea to drink, or an oil to anoint with.

A love spell, by contrast, is Venus and water. Rose, yarrow, cardamom, thyme. A coherent blend draws from this single register and produces a clear, focused working.

The witch can also cross-correspond for layered effect when the intention has more than one register. A love spell that wants passion alongside the tenderness might combine the Venus-water core (rose, cardamom) with a touch of Mars-fire (damiana, a pinch of ginger). A prosperity working that wants grounding alongside the growth might combine Jupiter-fire (cinnamon, sage) with Saturn-earth (patchouli) so the money comes and stays. The system is generative once a witch sees how the registers stack.

When Correspondences Conflict

They will. One herbal will say rosemary is Sun; another will say it can also be classified under the Moon for its memory associations; another will call it masculine fire while another calls it neutral. This is normal. Different cultural streams classified plants differently, and the conflicts in the tables reflect the conflicts in the source traditions. The conflicts do not invalidate the system.

The practical answer: the witch chooses a reference she trusts — Cunningham's Encyclopedia of Magical Herbs is the most commonly used in the English-speaking neopagan world, and it is the safest default — and she works from it consistently. Consistency within a system matters more than choosing the objectively right system, because no objectively right system exists. The witch who flips between three references on the same working confuses her own practice. The witch who picks one and works it for years builds a stable internal map.

Reading the Books

Every published correspondence reference reflects choices — which sources to draw from, which folk attributions to include, which to omit, and where the author's own intuitive sense filled in gaps. Cunningham is the most-used reference precisely because his choices are clearly stated and consistent. Other books are looser. A useful exercise for the witch building her own internal map: pick one plant she has worked with for at least a year, pull the entries for that plant from three different books, and notice where they agree, where they conflict, and where her own experience matches one source over the others. Where her experience matches a source, she trusts that source slightly more. Where her experience diverges from every source, her experience is winning that round. This kind of cross-reading is how the published system becomes a living personal one across years of practice.

The Intuitive Override

Correspondence tables are guidelines, not laws. There is one situation where personal experience supersedes the published book, and it matters: when a plant carries specific personal meaning for the witch.

A woman whose grandmother grew roses, who associates roses with her grandmother's funeral, may find that roses carry grief and ancestor work for her — regardless of what every reference book in the world says about Venus and love. That association is real. It is part of her own developing system. She uses roses for grief and ancestor workings because they work that way for her, and she pulls a different Venus-water herb for love. After enough years of practice, the witch's own relational and personal correspondences become the primary reference, and the published tables become consultation rather than gospel.

This is not permission to discard the system. The system is the starting place. It is the shared language of the tradition, the framework that lets a witch read any unfamiliar herb and orient quickly. The intuitive override is what mature practice builds on top of the system, not in place of it.

The Witch's Own Reference

The published books take a witch only so far. A magical journal kept across years of practice — noting which herbs worked for which intentions, which combinations blended well, which substitutions saved a working when the cabinet was missing the obvious choice — becomes a personal correspondence reference deeper and more accurate than any published encyclopedia. After a decade of disciplined journaling, the witch's own notes are her primary reference. The published books move to the secondary shelf. Cunningham becomes consultation; her own pages become the working manual.

This is the long arc of building a correspondence practice. Learn the system from the books. Apply it for years. Notice where it confirms and where it diverges. Record everything. The system becomes hers, layered onto the inheritance, and her plant magic begins to carry the specific charge of her own accumulated work.

The framework is the framework. The plants are the plants. The witch in relationship with both — the system held with structure, the plants held with intimacy — is the witch whose magic actually works.

IFS Parts Journaling

Correspondences help a witch read plants through shared patterns: element, planet, magical property, tradition, and personal experience.

For this practice, take five to ten minutes, or longer if desired. Find a notebook, journal, or blank page.

Choose one plant from the lesson or from your own beginning plant library.

Write its name at the top of the page.

Now read these three questions slowly:

What part of me wants a clear system to follow?

What part of me feels uncertain when correspondences conflict?

What part of me wants room for personal experience, memory, or intuition?

Notice which question has the strongest pull.

You do not need to answer all three.

Choose the one that feels most alive, and let that part write for a few minutes.

It may want certainty, flexibility, permission, accuracy, consistency, tradition, freedom, proof, or more time to learn.

When the writing feels complete, pause and look back at the plant name you chose.

Write down one correspondence you already know or want to learn about this plant.

It might be an element, planet, magical property, color, memory, scent, personal association, or traditional use.

Notice whether that correspondence feels clear, confusing, interesting, personal, distant, or alive.

If you want to go deeper, write one small note you would want to remember about this plant in your own future reference.

When the writing feels complete, put the pen down. Take a final moment to acknowledge and thank the parts of you that showed up for this practice.
