This is the bushy variety that thrives here - Indigofera tinctoria - in full bloom. I had one in my yard for years and it self-seeded until the great freeze about a decade ago and since then I haven't had any luck getting my seeds to grow up big and strong. Of course, I'm not the dedicated gardener I once was .... Click here for a great resource for growing indigo and extracting the blue dye.
Next week, a slow indigo pot not from pre-reduced crystals - but with indigo powder and henna.
See you then, Diane
