Flower is 3 to 4 inches tall and about 2 inches across, made up of a 2 to 3 inch long club (the “Jack”, or spadix) sitting in a tubular base with a hood (the “pulpit”, or spathe). The Jack is light green to reddish green. The pulpit is light green to purplish green and often dotted with white or purplish stripes. Separate male and female flowers are hidden from view on the lower part of the Jack inside the tube.
1 or 2 sets (male has 1, female 2) of compound leaves with 3 leaflets; each leaflet is up to 7 inches long and 3 inches across, generally oval with a pointed tip. The middle leaflet is generally larger than the side 2. The leaves can tower over the flower and hide it from view.
Notes:Jack-in-the-Pulpit has both male and female plants, though some plants are unisex and they can change gender. The leaves might be confused for a species of Trillium, but the vein pattern is distinctly different.
