Iris is a genus of 260–300 species
of flowering plants with showy flowers. It takes its name from the Greek word
for a rainbow, referring to the wide variety of flower colors found among the
many species. As well as being the scientific name, iris is also very widely used as a
common name for all Iris
species, as well as some belonging to other closely related genera. Source
Iris chrysographes, commonly known as the Black Iris, is a plant species that belongs to the genus Iris. It is native to S China and Myanmar (Burma), growing in meadows, streamsides, hillsides and forest margins. Other irises with black flowers include Iris nigricans (the national flower of Jordan), Iris petrana, Iris atrofusca, Iris atropurpurea, Iris susiana, and some varieties of Iris germanica. Iris chrysographes is easily cultivated and requires a fertile soil which does not dry out during the growth period. Grow in full sun. Hardy to USDA zone 4. Propagation by seeds or division in the spring. Cultivars must be divided. For cooler areas plants do best if planted in the spring. Source
