ORGANIC WELD SEEDS ~ Grown by the Irish Organic Seedsavers Association

Growing dye plants gives you a feeling of connection to nature, that is unique and I am delighted that you are thinking of taking that step. There can never be enough growers on our Earth and I do believe that growing your own colour adds yet another dimension to gardening and the plant world as a whole. If you can keep it organic, do, the colours are richer and the flora and fauna will thank you for it, as do we. Enjoy!

 Weld (Reseda Luteola) has been used for centuries to obtain a fast yellow dye. An attractive architectural plant with 1.5m high stems; a tall biennial, with lance-shaped, deep green leaves often with strongly wavy edges. Slender spikes of tiny yellow flowers are produced in summer. 

Weld is a biannual plant, and the entire plant is used in its second year. However, recent studies have shown, that most of the dye is situated in the flowers and leaves. However, the stem still has some yellow dye in it too, so I would always use the entire plant. 

Sow: In Spring, February to March, in a tray; seed is very fine. Germination can take up to 3 weeks.

Harvest: Leaves, flowers, entire plant in its second year

 So, what do you get in a pack of Weld Seeds?

Over 100 seeds in a package
