Tagetes Flower Natural Dye

Tagetes patula L. · Whole Dried Flowers · Grown in County Clare, Ireland

Tagetes flowers produce warm yellow, golden-yellow, ochre and orange-yellow shades on natural fibres.

Our Tagetes patula flowers are grown in small batches, hand-harvested and carefully dried in County Clare, Ireland. This smaller-flowered species is commonly known as French marigold. African marigold usually refers to the larger-flowered Tagetes erecta.

The open, delicate flower heads are suitable for dye extraction, bundle dyeing and botanical printing. Dried flowers generally produce softer, less defined prints than fresh or individually pressed flowers, but they can still be used to create scattered botanical marks and warm areas of colour.

Availability is limited by the growing season and the size of our annual harvest.

Tagetes as a dye plant

Tagetes patula is an annual flowering plant in the Asteraceae family. It produces smaller and generally more open flowers than Tagetes erecta, the species usually known as African marigold.

The flowers contain naturally occurring yellow and orange colourants, including flavonoids and carotenoid-related pigments. These can produce clear yellows, warm golds, ochres and orange-yellow shades.

Tagetes can produce beautiful colour, but it should not be considered one of the most lightfast yellow dyes. It is particularly suitable for exploratory dyeing, seasonal colour studies, botanical printing, sampling and textiles that will not be exposed continuously to strong sunlight.

Our flowers are grown in small batches using ecological methods, then hand-harvested and dried in County Clare.

Understanding the possible colours

Tagetes flowers may produce:

• Clear yellow

• Golden-yellow

• Warm ochre

• Orange-yellow

• Soft mustard

• Muted olive or khaki with iron

• Greenish-grey with a stronger iron modification

The final colour depends on:

• The quantity of flowers used

• The maturity and colour of the flower heads

• Drying and storage

• Fibre preparation

• Mordant

• Water chemistry

• Extraction temperature and time

• Length of time in the dye bath

• pH and modifiers

The flowers may appear strongly orange when dry but produce a predominantly yellow or golden colour on the fibre. Orange-yellow is possible, but a clear orange should not be guaranteed from every dye bath.

Dye extraction or botanical printing?

Dye extraction

Whole dried Tagetes flowers can be soaked and heated to prepare a yellow or golden dye bath.

• Suitable for immersion dyeing

• May be extracted a second time for a paler bath

• Flowers can be contained in a dye bag for easier straining

• A concentrated bath produces the best chance of a strong result

Botanical printing and bundle dyeing

The smaller, more open flowers of Tagetes patula can be used for botanical printing, contact printing and bundle dyeing.

• Whole dried flowers can create scattered marks and areas of yellow

• Individual petals can be separated and arranged on the cloth

• Rehydrating the flowers before use may improve contact

• Fresh or carefully pressed flowers generally produce clearer and more recognisable impressions

• Dried flower heads may crumble or produce softer, less defined prints

Always test the flowers with your chosen fibre, mordant, barrier and steaming method.

How much to use

25g can be used with up to:

100g dry fibre

Equivalent to 25% WOF - weight of dry fibre.

This can produce a pale-to-medium yellow or golden shade, depending on the fibre, mordant and extraction.

For stronger yellow, gold or orange-yellow shades, begin with:

50–100g Tagetes flowers per 100g dry fibre

Equivalent to 50–100% WOF.

These quantities are starting points. The final result depends on the harvest, fibre, preparation, water chemistry and dyeing method.

Suggested dyeing method

1. Prepare: Scour and mordant the fibre using a method appropriate for the fibre type. Wet it thoroughly before dyeing.

2. Soak: Cover the Tagetes flowers with water and leave for several hours or overnight.

3. Extract: Heat gently at approximately 80–90°C for one hour. Avoid vigorous boiling.

4. Strain: Strain the liquid carefully or contain the flowers in a dye bag.

5. Dye: Add the prepared fibre and hold the bath at approximately 80–85°C for one hour.

6. Deepen: Allow the fibre to cool in the bath. For a stronger colour, leave it in the bath overnight.

7. Finish: Rinse thoroughly and wash gently with a pH-neutral soap.

The result may range from pale yellow and golden-yellow to ochre, mustard or orange-yellow.

Optional cold dyeing method

Cold dyeing can be used as an experimental, low-energy method, although the result may be paler and less predictable than a heated extraction.

1. Cover the flowers with cool water and soak for 24–48 hours.

2. Gently press or stir the flowers occasionally.

3. Strain the liquid or contain the flowers in a fine dye bag.

4. Add thoroughly wetted, mordanted fibre.

5. Leave for one to three days, stirring or moving the fibre occasionally.

6. Remove the fibre when the desired colour has developed.

7. Rinse thoroughly and wash gently.

Keep the bath clean and monitor it during a prolonged room-temperature soak. Discard it if it develops an unpleasant putrid smell or visible mould.

Tips from the dye pot

Working with iron

A small amount of iron can shift Tagetes yellow towards muted olive, khaki or greenish-grey. We prefer to use Iron acetate, as it is gentler on the fibres and the environment.

1-3g iron per 100g dry fibre

Equivalent to 1-3% WOF.

Dissolve the iron thoroughly and use it as a brief afterbath. Watch the colour carefully and remove the fibre when the desired shade has been reached.

Too much iron may:

• Overwhelm the original yellow

• Produce a dull grey or brown result

• Make wool and silk feel harsh

• Weaken natural fibres over time

Colourfastness

Tagetes generally produces poor-to-medium colourfastness.

The brighter yellows and orange-yellows may fade with prolonged exposure to light. Performance depends on the fibre, preparation, mordant, depth of shade, water chemistry, extraction and aftercare.

Mordanting can improve colour uptake and wash fastness but does not make the dye fully lightfast.

Iron-modified shades may appear more resistant, although excessive iron should be avoided.

Protect finished textiles from prolonged direct sunlight and wash them gently with a pH-neutral detergent.

Tagetes is especially suitable for botanical printing, seasonal colour studies, sampling, artwork and textiles that will not be exposed continuously to strong sunlight.

Natural variation

This is a natural, locally grown botanical material. Flower size, shape, colour and dye strength may vary according to the plants, weather, harvest date, maturity, drying and storage.

The pouch may contain whole flower heads, loose petals and small pieces of stem or calyx.

Storage and safe handling

• Store sealed in a cool, dry place away from direct sunlight.

• For textile dyeing, botanical printing, paper and craft use only.

• Not for consumption or use in food, drinks, cosmetics or herbal preparations.

• Avoid creating or breathing flower dust.

• People sensitive to plants in the Asteraceae family should handle the material with care.

• Work in a well-ventilated area when measuring or processing dry flowers.

• Prevent contact with the eyes, mouth and open wounds.

• Wear suitable protective equipment when handling dusty material, dye baths and modifiers.

• Follow the safety instructions for every mordant and modifier used.

• Use dedicated dyeing utensils and containers—never food-preparation equipment.

• Keep away from food and out of reach of children and pets.
