If you’re acquainted with Curious Corners, you know that they want to share their passion for indigo dye with everyone. And if you’re an indigo enthusiast looking for a summer project, then they’ve got you covered with this little bundle of Japanese indigo seeds.

The pack contains a measure of Polygonum Tinctorium seeds, as well as instructions on how to plant and grow the beautiful plant. Before the arrival of Indigofera, Polygonum Tinctorium was the primary source of indigo dying in East Asia, and you can grow your own right up until it sprouts its pink buds — or attempt to produce your own indigo dye by harvesting the plant before it flowers. Either way, you’ll have an organic connection to your favorite dye right in your backyard.

Available from Curious Corners for $12.
