Life Cycle of an Indigo Plant


This photo log documents the growing season of a Persicaria Tinctoria Indigo plant from seed through dye. The plant began to germinate after 18 days in the soil. Planting seed was covered in germination.

Day 18


Seed visible at center with radicle beginning to emerge and root. This was an unusually extended germination period because of the cool temperatures (40s and 50s F) and lack of light, as the seeds were planted just days after the winter solstice in Los Angeles, CA, 2015.
