The stem decides the wire.

Choose the wiring method from the flower's anatomy, never from its name. Learn the ten methods on this page and you can wire a bloom this guide never mentions. The A to Z index below is for the days you would rather look it up.

First principles

Which gauge of wire should you use?

Size the wire by what it has to hold up, not by what looks right. Gauge runs backwards: the higher the number, the finer the wire. Pick the lightest gauge that holds the head still when you tip the stem horizontal. Too heavy and the piece becomes a brick that fights the bride's hand; too light and the head nods within the hour.

GaugeUS ≈mmUK/EU sizeWhat it holdsReach for it on
161.291.25 mmArmature and frames, not flowersCage and cuff structures, hand-tied collars, heavy hanging work
181.021.00 mmThe heaviest single headsSunflower, amaryllis, allium, protea, lotus pod, large succulents

US wire is sold by gauge number, European wire by millimeter, and the two ranges don't line up exactly. A US 22 gauge and a UK 0.71 mm are the same working wire, even though the conversion says 0.64. Buy by feel, not by arithmetic. Green enameled wire disappears into stems; white is for anything you'll tape white, and paddle wire is for continuous binding, never for mounting a single head.

First principles

How does floral tape hold?

Floral tape is not an adhesive. It is wax that bonds to itself, and only once you stretch it: pulling activates the wax, so each wrap welds to the one beneath. Work half-width for anything finer than 22 gauge, since a full-width wrap on a stephanotis pip is a tree trunk. Hold the tape at roughly 45° to the wire, pull it taut enough to feel it thin, and spiral downward with each pass covering half the last.

0145°
Start tight under the calyx, tape angled 45° to the stem.
02
Spiral down under constant tension, half-overlapping each turn.
03
Pinch and tear, never cut. The torn tail welds flat.

Color: moss/nile green for anything that reads as stem, white for bridal work where the stem shows against a gown, brown for woody and dried material, and black only when the design asks for it. Parafilm-type tape is thinner and near-invisible but won't grip a heavy mount; crepe tape grips harder and builds bulk. Never tape over a wet stem, because the wax won't take.

The ten methods

Which wiring method does a stem need?

Read the stem before you reach for wire. What the stem is made of decides the method, and the flower's name only tells you what it probably is. Find the line below that describes what is in your hand.

  • A firm green calyx under the petalsPiercing. The calyx is the strongest point on the flower, so the wire goes straight through it. Roses, carnations, dahlias, peonies, lilies. 22 gauge, or 20 for heavy heads.
  • A flat head of many small florets, with no calyx to speak ofHook wiring. A small hook buried in the center anchors the head from inside. Asters, spray mums, daisies, cornflower, strawflower. 22 to 24 gauge.
  • A leafStitch wiring. One stitch behind the midrib turns a flat leaf into one you can shape. Ivy, galax, salal, magnolia, lamb's ear. 26 to 28 gauge.
  • A hollow stemInsertion wiring. The wire runs up inside the stem, so nothing shows and the flower can still drink. Tulips, gerbera, amaryllis, bells of Ireland, zinnia. 18 to 20 gauge.
  • A soft, fleshy or latex-bleeding stemCorkscrew wiring. The wire coils around the outside and never breaks the skin. Calla, anemone, sweet pea, tweedia, euphorbia. 24 to 28 gauge.
  • A woody sprig, a short clipping or a berry clusterDouble leg mount. Two wire legs give a usable stem of any length to something that has none. Waxflower, hypericum, eucalyptus, boxwood, brunia. 20 to 24 gauge.
  • An orchid or a tubular bloom taken off its sprayCross wiring. Two fine wires cross through the throat, just behind the column. Phalaenopsis, cattleya, cymbidium, dendrobium. 22 to 26 gauge.
  • No stem at allCross-piercing. Two wires crossed through the firm base carry real weight. Succulents, camellia, air plants, a head that snapped at the neck. 18 to 22 gauge.
  • One large bloom where you need several small onesFeathering. Split the bloom, collar each bundle in its own calyx and bind it. Carnations for boutonnieres. 28 to 30 gauge to bind.
  • A spike of florets where you need single onesPipping. Each floret comes off the spike and gets its own fine wire. Hyacinth, stephanotis, delphinium, tuberose. 28 to 30 gauge.

When two lines apply, use both methods. A fully blown peony is pierced through the calyx to hold the head and given an insertion wire to hold the neck. AIFD calls that combination T wiring. The same logic covers a heavy gerbera: hook the head, insert up the stem.

01
Aim across the widest part of the calyx, not the neck.
02
Push straight through. Leave the legs even on both sides.
03
Bend both legs down; coil one over stem and partner.
Method 01

Piercing

AIFD: piercing · UK trade: stitching, or piercing

The default for anything with a firm green calyx holding the petals: roses, carnations, mums, dahlias. A single wire goes horizontally through the calyx, the two legs bend down against the stem, and one wraps the other. The head now pivots on the wire instead of on its own neck, which is the part that snaps.

22g standard20g for peony & dahliaTape half-width
How it failsPierce too high and you go through the petal bases, and the head shatters in a day. Pierce too low and you're in hollow neck, which crushes. The target is the fat green base where the calyx flares off the stem.
01
Feed the wire up the stem, through the center of the head.
02
Bring it out the top and turn a short, tight hook.
03
Draw it back until the hook vanishes into the center.
Method 02

Hook wiring

AIFD: hook wiring · UK trade: the hook method

For flat, many-petaled composite heads with no calyx worth piercing: asters, spray mums, daisies, gerbera centers. The wire runs up through the stem and out the top of the head, gets a small hook bent into it, then is drawn back down until the hook disappears among the florets and grips from the inside.

22–24gHook ≈ 5mmGreen tape
How it failsA long or loose hook sits proud of the florets and catches on fabric. Make it short and close it tight. On a gerbera, hook the head and support the neck separately. One wire cannot do both jobs.
01
From the back, take one small stitch across the midrib.
02
Fold both legs down the back, level with the stem.
03
Coil one leg over both. The leaf now has a stem.
Method 03

Stitch wiring

AIFD: stitch wiring · UK trade: stitch support wire

The only respectable way to wire a leaf. Working from the back, take a single small stitch across the midrib about a third up from the base, then fold both legs down behind the leaf and wrap one around the stem and its partner. The leaf keeps its natural curve and you can now shape it, which is the whole reason to wire foliage at all.

26–28g30g for fernStitch ≈ 8mm
How it failsA wide stitch tears the midrib the first time the leaf is bent; a stitch too near the tip does nothing. If the wire shows from the front you've gone through the blade instead of behind the rib. Start again on a fresh leaf.
01
Cut the stem square. The hollow core is your channel.
02stop
Feed it up inside. Stop short of the head, never into it.
03
Tape head-down to lock the wire and seal the cut.
Method 04

Insertion wiring

AIFD: insertion · UK trade: internal wiring, a form of support wiring

Hollow-stemmed flowers get a wire pushed up the inside from the cut end, stopping just below the head. Tulips, gerbera, amaryllis, bells of Ireland, gladioli, zinnia. Nothing shows, the stem stays intact, and the flower can still drink. That matters, because these are exactly the stems that collapse in a warm room.

18–20gStop 1cm shortKeeps water uptake
How it failsDriving the wire up into the head splits it from the inside and it browns overnight. Tulips keep growing after cutting and will curve around a wire that's too short. Run it the full length of the stem, or accept the bend as a design feature.
01
Lay the tip against the stem. Don't break the skin.
02
Coil down in open, even turns: snug, never tight.
03
Tape over it. The stem is supported, never punctured.
Method 05

Corkscrew wiring

AIFD: corkscrew wiring · UK trade: external wiring

For stems too soft, fleshy or precious to pierce: orchids, calla, anemone, sweet pea, ranunculus, and anything that bleeds latex. The wire coils loosely around the outside of the stem from just below the head downward. It's the gentlest method and the only one that leaves the stem's plumbing completely intact.

24–28gOpen turnsZero damage
How it failsPulled tight, the corkscrew strangles the stem and the head droops within hours. You've made a tourniquet. The coils should hold the stem, not grip it. If the stem dents, you're too tight.
01
Hold the wire behind the stem, a third up from the end.
02
Bend one leg down; coil the other twice over stem and leg.
03
Two equal legs emerge below. That's your new stem.
Method 06

Double leg mount

UK trade: double leg mount · AIFD: nearest are cluster wiring and cranking

How you give a stem to something that hasn't got a usable one: woody sprigs, short clippings, berry clusters, foliage tips. A wire is held horizontally behind the stem, one leg bends down, and the other wraps twice around both stem and leg before dropping to join it. You end with two equal legs: a new stem of any length you like.

20–24g by weightSingle-leg for lightWrap twice, no more
How it failsMount too high on the sprig and it pivots and hangs; too low and it pulls out. A third of the way up is the balance point. More than two wraps builds a lump you'll feel through the tape.
01
Enter the throat just behind the column, side to side.
02
Cross a second wire at 90° through the same point.
03
Gather all four legs below and tape them into one stem.
Method 07

Cross wiring

AIFD: cross-piercing · UK trade: cross wiring

Orchid blooms have no calyx and almost no neck. They hang off the spray on a thread. Two fine wires cross at right angles through the throat just behind the column, and their four legs twist down into a stem. Cymbidium, phalaenopsis, dendrobium, and any tubular bloom you're removing from its spray. Mechanically this is cross-piercing worked through a throat rather than a base: the same two wires in different tissue.

24g cymbidium26g dendrobiumAdd a water vial
How it failsWire through the lip instead of behind the column and the flower's face collapses forward. Orchids off the spray have hours, not days. Vial them, or wire them the morning of.
01
Cut across the calyx, keeping the green collar intact.
02
Divide the petals into three or four even bundles.
03
Collar the bundle, bind with 28g, tape into a new stem.
Method 08

Feathering

AIFD: feathering · UK trade: feathering

One standard carnation becomes three or four miniature blooms. Cut across the calyx, keep the green collar, divide the petals into even bundles, wrap each bundle in a piece of the calyx and bind with fine wire. Less fashionable than it once was, and still the most economical way to fill a hundred boutonnieres.

28–30g bind3–4 per bloomHalf-width tape
How it failsSkip the calyx collar and the bundle splays open the moment it's taped. Uneven bundles read as damaged flowers rather than small ones, so divide by eye and then even them up before you bind.
01
Push a wire through the firm basal stem, not the petals.
02
Cross a second wire through at right angles to the first.
03
Bend all four legs down, twist, and tape as one stem.
Method 09

Cross-piercing

AIFD: cross-piercing · applied to a base rather than a calyx

What you do when there's no stem at all. Succulents, gardenias, air plants, a bloom that snapped off at the neck. Two wires cross through the firm basal tissue at right angles, and the four legs twist down into a stem strong enough to carry real weight. The heaviest method in the book, and the only one that holds a hen-and-chicks on a lapel. The same crossed pair as cross wiring, driven through firm basal tissue instead of a flower's throat.

18–20g succulent24g gardeniaTwo wires, four legs
How it failsWire through leaf tissue instead of the basal stem and the rosette pulls apart in your hand. On a gardenia, stitch the calyx rather than cross-pierce it, and handle it only by that calyx. A fingerprint on the petals browns within the hour.
01
Pull one floret free with its short tube intact.
02
Hook 28g through the center and draw it down the tube.
03
Tape each, then bind three or five into one sprig.
Method 10

Pipping

UK trade: pipping · AIFD: nearest is hairpin wiring

Taking a single floret off a spike and giving it its own stem. Hyacinth, delphinium, lilac, tuberose, stephanotis, gladiolus. A fine wire hooks through the center of the floret and draws down through its tube; tape it, then bind three or five pips back into a sprig with far more control over shape than the spike ever gave you.

28–30gOdd numbersSame-day work
How it failsPips are cut flowers with no stem and no reservoir, so they last a day in open air. Hyacinth pips also weep a sap that irritates skin. Wear gloves, mist rather than soak, and hold them in a hydration chamber (below) if you need them to last past tomorrow.
Holding wired work

How do you keep wired flowers alive without water?

Hold them in saturated air. A pipped floret has no stem, and a pierced or mounted bloom has one that no longer draws: once the wire takes over the stem's job, the flower cannot drink. What keeps it alive for two or three days is humidity around the petals. Flowers take up moisture through the epidermis, and at 95% humidity transpiration all but stops, so the bloom holds what it already has instead of losing it to the room. The chamber is how you buy the time to build ahead.

In cross-section: a sealed lid, a damp liner at the base, and a rack holding the taped blooms clear of standing water. Condensation belongs on the walls, never on the petals.

Build it to these numbers

Any sealing container works: a clear storage bin, a cooler, or a florist's box lined with plastic. A wrung-out towel or a shallow tray of water at the base, a rack or crumpled tissue above it, and a lid that actually closes.

What kills it

Condensation on petals. Standing water on a petal becomes botrytis within a day, and gray mold spreads through a closed box faster than anywhere else in the cooler. Mist the walls of the chamber, never the flowers, and open it once a day to let the air turn over.

Ethylene. A sealed box concentrates it. Keep fruit, anything ripening, spent blooms and dying foliage out of the same cooler. Wired flowers are already stressed and will show it first.

Contact with the liner. A petal edge resting on damp towel browns overnight. The rack is not optional.

An unsealed base. Tape all the way over the cut end so the wire entry can't wick moisture up into the calyx and brown it from the inside.

Worth the chamber: gardenia, stephanotis, lily of the valley, hyacinth and tuberose pips, orchid blooms taken off the spray, camellia. Everything on that list is a same-day flower in open air and a three-day flower in saturated air, which is the difference between building the morning of and building ahead.

Cross-reference

What else might your team call these methods?

Wiring terminology is not standardized, so expect your team to use different names. AIFD, the British system that City & Guilds and WorldSkills teach from, and the Australian and Asian trade schools all name the same handful of techniques differently, and a few names mean different things depending on who trained you. Insertion is an AIFD name for running a wire up a hollow stem; in some British sources the same word describes pushing a wire through a calyx. This guide leads with the AIFD name where one exists, and keeps the British name where AIFD has no direct equivalent.

If you're studying for the PFDE, learn those from the AIFD guide rather than from this page.

A to Z

How do you wire each flower?

Look it up below. Every entry names the gauge, the method, the tape color and the one thing that goes wrong. Tap a method chip to see everything that takes the same treatment. Where a flower can be handled two ways, the listed method is the one that survives a warm reception.

Method
FlowerFormWireMethodTapeHandling note

Everything stems from design.

Gauges assume standard enameled florist wire and a bloom in good condition. A soft, blown or thirsty head always wants one gauge heavier than listed. Everything here is written for personal flowers: bouquets, bouts, corsages, combs and cake work. Arrangements in foam follow different rules.

Wired flowers are cut off from water. Build as late as the timeline allows, hold them at 38–40°F in a hydration chamber, and never in the same cooler as fruit.
