Is it time for a sex change?

Jack-in-the-Pulpit is one of Ohio’s most unique wildflowers. The “Jack” part of the flower (the spadix) is a cluster if indistinct flowers. The “Pulpit” is made of modified leaves, called a spathe. Although usually described as a clergyman preaching from his pulpit, the shape of the spadix has generated other, less clerical, names referring to various body parts. (We’ll leave this to your imagination). The entire plant contains calcium oxalate crystals which cause burning if eaten raw. One account describes the Meskwaki Indians putting ground root into mat left for their Sioux enemies. Apparently the meat tasted fine on ingestion, but several hours later caused severe pain, often resulting in death. The roots were reportedly eaten by many Native Americans after being thoroughly cooked or dried to remove the crystals. Perhaps the most unique feature of this plant, however, is that it can change sex as needed to adapt to environmental conditions. Because it takes a lot more energy to be female and produce fruits, plants will often spend several years as males, storing food. When the plant has enough energy, a sex change occurs and the plant produces fruit. So from sex changes to preacher men, this plant is a great conversation starter for your garden.
Jack-in-the Pulpit will be available at our Native Plant Sale on April 30 and May 1. View the plant catalog for a complete list of plants.
