Seeds of Japanese indigo Väritattaren siemeniä
Siementen itävyyttä en vielä tiedä, se pitää kokeilla, mutta hienoa, että vihdoin onnistuin saamaan vähän omia siemeniä, ja tiedän jatkossakin, että se voi onnistua:)
Väritattaren siemeniä en ole valitettavasti edelleenkään nähnyt missään Suomen siemenkaupoissa, mutta Saksasta niitä myy Ruhlemanns vanhalla nimellä Polygonum tinctorium (näiden uusi tieteellinen nimi on Persicaria tinctoria). Englannista niitä myy Wildcolours. Ranskasta väritattaren siemeniä löytyy Couleur Garance'lta.
I finally managed to get my own seeds from japanese indigo this winter. Here in the north with long daylight the flowering starts so late, that the frosts come at the same time, in October. In southern countries the dark nights come earlier and so also the japanese indigo may start to flower as early as August and seeds ripen also early.
I had tried to get seeds by taking cut stems inside and put them in water, but I never got any seeds from them. They started wilting before the seeds came. Perhaps the flowerheads need to be visible before cutting the plants? Now I took one big plant in a pot inside in October and it started flowering in late October early November, and seeds ripened after Christmas. I cut the flowerheads with seeds to a plate and let dry, picture below. Now the whole plant has wilted and died, it is clearly annual and dies after seeding.
I haven't tried the viability of the seeds yet, but it's great that I managed to get some of my own seeds now, and that now I know I can do this in the future:)
You can't buy seeds of japanese indigo anywhere from Finland, but Ruhlemanns in Germany sells the seeds (by the old name Polygonum tinctorium, the new latin name is Persicaria tinctoria) and also Wildcolours in the UK sells them. In France Couleur Garance sells them and in United States you can find these seeds from Companionplants seed catalogue.
