Japanese indigo finally sprouts!

After many weeks, and on the third attempt, my Japanese indigo has finally sprouted!

Now that I’ve managed to make a textile sample out of the wisteria vine that’s trying to eat my house, I’m on to a more ambitious project: a wisteria-fibre & hemp furoshiki (wrapping cloth), block-resist dyed with indigo.

Since I’ve got a limited amount of wisteria to work with, I’m planning to use commercial hemp thread as the warp.

And, to explore Japanese dyeing techniques, I’m working on growing Japanese indigo – Polygonum tinctorium.

It’s a cousin of Japanese Knotweed – which I’ve been battling for years – and I was dubious about letting it into my garden, but it looks like I needn’t have worried; it’s amazingly slow to germinate! Or at least, amazingly slow to germinate here in Toronto.

To start with, the seed is hard to find. My usual sources – Richter’s and Humber Nurseries – don’t have it, and most of the few suppliers on the web were out of stock by the time I tried to order it last winter. I finally found some on Etsy.

My first attempt to start the seeds was a dismal failure; nothing happened. It needs to be “evenly moist”, and after three weeks or so of nothing happening, I got less careful with the watering.

The second attempt was scuttled by squirrels. They decided the nice, well-tilled raised bed I used was the perfect place to dig.

Finally, I filled a big, self-watering pot with fresh organic soil mix, sprinkled the rest of the seeds on top (they need light to germinate), tied bird netting over the top, and kept a careful eye on the moisture level.

Nothing kept happening. For at least three weeks. Maybe four – I’ve lost track. Finally yesterday, long after I had pretty much give up hope, a bunch of tiny sprouts popped up.

Yay!

Now I have a big flower pot studded with pairs of  baby leaves. Maybe now it’ll pick up speed and behave more like a knotweed – I’m not sure whether to cheer or worry!
