ANNUAL WELD SEEDS – Reseda luteola

(Traditional Yellow Dye Plant)
Dye Colour: Yellow
Produced in: Ireland

Reseda luteola, commonly known as Weld, is one of the most important historic yellow dye plants, valued for its exceptional clarity and lightfastness. Its tall, slender flower spikes and narrow leaves produce strong, clean yellows that form the foundation for greens and oranges when overdyed with indigo or madder.

Weld is normally a biennial, flowering in its second year. However, this particular variety shows the unusual and reliable trait of flowering in its first year under Irish growing conditions. This makes it especially valuable for dyers seeking faster access to usable dye material, while still maintaining good colour quality.

A cornerstone plant for professional natural dye practice, Weld remains central to gardens focused on consistent, high-grade colour production.

Dye fastness: Excellent (one of the most lightfast natural yellows)

🌱 Basic Growing Information

Sowing period
Mid-March to mid-April indoors
Direct sow from mid-May

Germination time
8–14 days

Height
100–150 cm (40–60 in)

Preferred location
Full sun with well-drained soil
Tolerant of poor or dry ground

✂️ Harvesting for Dye

Harvest the whole plant when approximately half of the flower spikes are in bloom, which is when dye content is at its highest. Cut at the base and use fresh, or dry thoroughly for later use.

Leaves, stems, and flower spikes are all suitable for dyeing and produce strong, clear yellows.

Flowers and plant material may be used fresh or dried for dyeing and eco printing.

🌼 About This Variety

This variety was identified during our 2024 Weld variety trials. While several trial varieties flowered in their first year, none did so as consistently as this one.

As it is the flowering plant that is used for dyeing, this trait offers a significant practical advantage by saving a full growing season. However, dye content testing showed that this variety produces slightly paler colour than our traditional biennial Weld (see Sample No. 5 in the final product image).

This presents an important choice for growers and dyers:

• A usable crop in one year with slightly lighter colour
• Or a brighter crop requiring two full growing seasons

Long valued in traditional and contemporary natural dye practice, Weld remains a cornerstone plant for dyers seeking consistent, high-quality colour from their own gardens.

Life cycle
Biennial

Sowing
Mid March to Mid May

Germination time

HAWTHORN BERRIES DYE
Dye Colour: Original Beige/Yellow | With Iron: Silver Grey, Grey Green | Country of Collection: Hungary

Hawthorn berries are rich in tannins and provide soft and earthy tones, ideal for dyeing wool and silk. The natural beige or yellow hue can be modified by adding iron, creating subtle shades of silver grey, grey, or grey-green. The resulting colours are earthy and gentle, as seen in the yarns dyed with Hawthorn, giving a timeless, organic feel to any fibre project.

In addition to dyeing, I sometimes use Hawthorn berries to slightly lower the pH in dye baths, such as when dyeing with Madder to create richer orange tones.

Colour Fastness: Poor - Medium when using a mordant.

Colour Outcomes by WOF Ratio:

• 100% WOF Dye (Hawthorn): Produces a soft beige or yellow.
• After mordant with Iron: Creates silver grey, grey, or grey-green hues.
  

Basic Recipe for Dyeing:

Ingredients:

• 10% Alum
• 100% Hawthorn
• 1-3% Iron

Instructions:

1. Mordant yarn with 10% Alum, either hot at 85°C (185°F) for 1 hour or cold for 12-24 hours.
2. Extract Hawthorn for 1-2 hours at 85°C (185°F). Strain dye.
3. Add mordanted yarn to dye liquor and leave for 1 hour at 85°C (185°F).
4. Add Iron to modify the colour, if desired. The more iron you add, the greener the shade becomes. Aerate between dips and avoid leaving the yarn in the iron bath for more than 5-10 minutes.
5. Rinse and hang to dry.

Bring the beauty of earthy, organic hues to your fibre projects with Hawthorn, a dye plant with centuries of natural tradition.

SUITABILITY

Over the past year, I have noticed that many crafters use natural dye kits to dye Cotton, linen and other plant based fibres. Unknown to them, the mordanting instructions used for Wool or Silk are unsuitable for plant based fibres and often will result in pale, short lasting colours.

We have remedied that with our collection of ever growing dye kits and stand alone dye recipes. You can now choose the dye kit according to your fibre need ~ protein (wool & other animal fibres) or plant based fibres (linen, hemp, cotton)
