Recommended by Our Growers
There are a few hundred species of Irises on the planet, so it is not surprising that these plants are well-known and well-loved by humans all over the world. They are rich in symbolism. In Greek mythology, Iris was the goddess of the rainbow and was a bridge for women to the afterlife; Greeks would therefore plant Irises on women’s graves. According to the ancient Egyptians, Irises symbolized wisdom, faith, and courage. In North America, the Northern Blue Flag Iris was once considered a healer of a variety of ills. This was a dangerous idea, because the plant is poisonous when ingested if not prepared correctly.
Over the years, many of our native wetlands have been drained or filled in. Long considered useless, wetlands are actually precious to wildlife, water quality, and the health of the whole planet! We should preserve those spaces and the plants that flourish there. Northern Blue Flag is one such species that we can’t afford to lose. Besides service wildlife, it’s a living water filter that cleans mucky water naturally.
How to Grow
Northern gardeners rejoice! Native to the upper Midwest, New England, and eastern Canada, Northern Blue Flag can handle the coldest winters Mother Nature can hand out. It is very easy to grow, as long as it is given full sun, rich soil, and consistent moisture. Northern Blue Flag will grow in up to four inches of standing water. Because it is poisonous to eat, deer don’t bother it. The roots are toxic, too, and even touching them may irritate some people’s skin. Be sure to wear gloves if you decide to divide your plants (this is an easy way to make more).
