Part VIII: Polygonum Progression
I admit, of all the dye plants I chose to grow for Seed to Skein 2010 Dye Garden Project, Polygonum tinctorium is the species which I had the least expectations for its survival in Oklahoma. After all, we are a long way from Japan. On the other hand, I assumed Woad, Isatis tinctoria, to be the hands-down no problem plant but it is plagued with the same issues I am having with Weld in the clay loam soil (see ‘Part VII: Weld Rescue’). Luckily I was so confident about Woad’s ability to survive that I planted seed in my sandy loam “wild country garden” and it is happy taking care of itself.

So I am very pleased to say that the Japanese Indigo appears to like Oklahoma! It likes nutritious pH neutral ground and does not seemed bothered by our clay loam soil. The unusual amount of rainfall is most likely working in my favor, but so far it is healthy, growing and abundantly beautiful. The leaves are dark green, rich and lush looking. They are about 28" tall by mid July. The mulch is doing an excellent job of suppressing the darn morning glory vines that come up everywhere.

Initially there were some mealy bugs, those white suckers, but they were everywhere and not only in my garden but friend’s gardens as well. I let them be and they sorted out their natural balance.

Grasshopper on first Polygonum Flower,
mid July, 2010
On 11th of July, within days after posting ‘First Flowers’ (see ‘Part VI: First Flowers’) we discovered the first Polygonum tinctorium flower! Tiny little pink flowers just beginning to open. They are very beautiful. The first cutting of the leaves is around the corner.
