Heirloom Seeds Heirloom Plants Flower Seeds Rare Seeds 20+ Seed Pack Description: Known as False Indigo in the U.S., it grows well from flower seeds, and historically the plants were in high demand for the dye that was made from the blue and purple flowers. A shrub-like perennial, it is a member of the pea family and thrives in cooler climates. An upright plant, the flowers look like blue peas, followed by dark, glossy pea pods and a glossy leaf pattern. Also known as Wild Indigo or Blue False Indigo, this native plant needs at least six hours of direct sunlight per day. Since this plant does not transplant well, it should be direct sown. The seed will need to be scarified; to accomplish this, pour 150 degrees F water over the seed and let it soak overnight the day before planting. In late fall, plant 2-3 seeds per plant, 1/8" deep, spaced 24-36" apart. For spring planting, the scarified seed will need to be mixed with moist sand and stored in the refrigerator for 10 days before planting. Germination should take place within 15-20 days after the cold cycle.
