An easy to grow member of the knotweed family, Japanese Indigo is a great option for those looking for a natural blue dye! These seeds are carefully saved from my own dye garden in Minnesota. I never use pesticides or herbicides and all seeds are hand collected and sorted. **These seeds were harvested in 2022 for 2023 season planting**

Japanese Indigo (Persicaria tinctoria or Polygonum tinctorium) is a tender annual in most temperate locations (think peppers and tomatoes) and prefers rich soil and warm, rainy weather. I’ve found that starting seeds indoors gives me the best results. Leaves can be harvested after the plant is established, or cut about the top 2/3 of the plant – the remainder will grow more stems, and once you strip the leaves the stalk can be re-rooted!

The green leaves of the Japanese Indigo plant are where you will find the dye. It takes some coaxing to get a blue color from the leaves, either via a reduction method or traditional vat. I recommend Jenny Dean’s Wild Color book as an excellent resource. Leaves can also be used to dye after drying!
