Indigo pigment grows naturally in the leaves of a large number of plant species from around the world. This plant, Persecaria Tinctoria, also know as Polygonum Tinctorum, has been a staple source of blue in East Asia for millennia. It is known for being relatively easy to grow. It thrives in full sun, rich soil and moderate water.
Exercise your thumbs, green or otherwise, by adopting and caring for some of these plants yourself!
The pigment can be extracted from the mature leaves and used to dye all types of natural fibers.
HARVESTED 2018 for 2019 PLANTINGS
This packet contains at least 100 seeds of natural indigo. Among its many names are Persecaria Tinctoria, Polygonum Tinctorum, Japanese Indigo, Dyers Knotweed, etc.
I've found that the most efficient way to grow these seeds is to bulk germinate by planting in troughs of soil in an open flat, then transplanting the small seedlings into their own cells as their first true leaves appear. Finally, when the seedlings are at least 4 inches tall and have a few sets of leaves, transplant into the ground in full sun. Be sure to transplant after all threat of frost has passed as this plant is NOT frost hearty and will be decimated by below freezing temperatures.
