Indigofera spp

Several species of this genus of the Leguminoseae are cultivated for a natural blue dye called indigo, or anil. This dye has been used for at least 4000 years, and it is superior to the European woad (Isatis tinctora). However, with the development of analine dyes, the world market for natural dyes collapsed. Induced deficiencies

Occasionally, a nutrient deficiency can be induced, in spite of the fact that there is an adequate amount of that nutrient available. For example, water softeners replace calcium salts with sodium salts. An excess of sodium salts can induce a potassium deficiency. For this reason, house plants should never be watered with softened water.
