Persicaria Tinctoria, Japanese Indigo Seeds, Dye Plant Seeds

Persicaria Tinctoria (japanese indigo leaves) is one of the easiest and cost efficient ways to produce a beautiful indigo dye. They are vigorous plants and produce an abundance of side shoots for cut-and-come-again plant dye material and, as they mature, pretty clusters of pink flowers too. How to Grow: Start indoors 6-8 weeks before last frost. Sow seeds shallowly and provide warmth, light and even moisture. To aid in germination, seeds may also be soaked for 12-24 hours in advance. Transplant outdoors 12" apart after danger of frost has passed. Harvest as desired by cutting above a branching point, ideally before flowering for dye.
