Not a very focused picture but here is a bunch of cut Japanese Indigo flowering stalks. The weather is getting colder so these are brought into the house so the flowers will make and set seeds.
Japanese Indigo drying on racks. These were a thrift store find - toddler cots. I put toilet paper tubes on the feet to make more space between each level. After the leaves are dry I'll separate the stalks (those go in the regular compost) and compost the leaves in a burlap-lined bucket. Then form into cakes and dry. This preserves the pigment. It would be better if I could dry these outside in the sun but we aren't getting much of that at this time of year!
