Blue Ginger, Dichorisandra thyrsiflora, is an ornamental tropical plant that resembles ginger, but isn’t a true ginger. In tropical locations they can be planted outdoors, but also can survive indoors for those who experience colder climates. They produce beautiful blue flowers that last for months and flower throughout the year and are prized around the globe.
Blue ginger is a sterile plant, and only can be propagated by cuttings (or root divisions). Many people have success with just planting the stem cutting with 1 or 2 nodes, into moist sterile media in pots and keeping an eye on them. But if you prefer you can try setting up a humidity bag for them.
