Japanese Indigo is a popular dye plant used to produce brilliant blue color on cloth. This variety will grow well in most soils and yields white and pink blossoms late in the season. The leaves are picked for dyeing and there are several methods to choose from. The seeds start easily in potting soil and should be started indoors around the same time as tomatoes.
