A brief word about indigo containing plants first. In my studies I have learned that indigo blue can be isolated from at least three different plants: woad (Isatis tinctoria), "bagdad" indigo (Indigofera tinctoria), and Japanese Indigo (Persicaria tinctoria/Polygonum tinctorum). The first time I tried Indigofera tinctoria I only got two plants to germinate at all and they yielded no blue. T
he same year, 2015, I grew Isatis tinctoria and yielded a little success but only sufficient florey in my vat to paint out one circle of blue that I evidently didn't take pictures of. 2016 was the summer we moved. There were no extant gardens on the property and not enough energy to install them until 2017.
In 2017 I grew woad, Isatis tinctoria, in three large red planters in the front garden at the new house in Windham. I was more careful to feed the plants well in 2017. Two of the pots were only "50/50" mix from the garden center who said "It's really about 70/30 loam and Benson's. Any richer would burn your plants." And the third pot included amazing compost from an acquaintance of my mom who makes it with kitchen scraps and mess from his chicken coop.
