The name of this wildflower, Jack-in-the-pulpit, comes from looking like a preacher in a pulpit, although in this case, the preacher probably isn’t Jack as the plant is female. The double set of compound leaves indicates that the plant is female although the plants can change gender from year to year.

The male plants tend to be smaller and also allow pollinators, like the fungus gnat, to escape more easily due to a small hole at the bottom of the slippery spathe after coming into contact with pollen. Females flowers, without the hole, are more likely to trap the pollinators that may be carrying the male pollen, giving it a better chance of successful pollination.

Green flowers often get overlooked since they don’t stand out like the other colors. But at least “Jack” had a hood over his head to protect from the patchy frost overnight. New seedlings need three or more years of growth before they become large enough to flower.  The Jack-in-the-pulpit flowers are unisexual and normally the larger plants are female.

The floor of my woods has splotches of bright red from the berries of the Jack-in-the-Pulpit. But in this case it is more like Jill-in-the-Pulpit, as only the female plants produce the berries, but the plant can switch back and forth from male to female depending on the previous year’s environment and how much nutrients were stored in the corm. So last year much have been a good year since a lot of female plants this year, but they may see many “sex changes” in their lifespan as some plants can live for a hundred years. But be careful touching the berries as they can cause irritation to sensitive or broken skin when touched.

Some wildflowers were not able to put on a show this year, especially my trilliums which the deer devoured on me, but the Jack-in-the-Pulpit are out in full force this year and the deer must not like the taste of them and a good reason for it since the leaves are poisonous. But the flower is a weird looking plant and what we think is the flower is really deep inside and at the bottom of the ‘pulpit’, as the pulpit is the spathe and the ‘minister’ is a spadix. The true flowers are located at the very base of the spadix.

The Jack-in-the-Pulpits are also unusual since each plant has a particular sex instead of having both parts on the plant. The male has little anthers at the base of the ‘Jack’ and females have a cluster of green berries, which turn red in the fall.

Even though separate male and female flowers, pollination does occur with a bit of trickery as the ‘pulpit’ produces the smell of mushroom to attract tiny insects. And since the hood blocks the sunlight and the lower part of the pulpit is paler and lets more light in so the insects move down to the light and picks up or drops off pollen.

The flower will also change sex from year to year as the female takes more resources to produce the baby plants, so if the plant’s corm was able to store a lot of food, then it will be a female plant the next spring and shoot up two leaves. Otherwise with less nutrients, the plant will be a male (as he doesn’t have as much work to do producing pollen), and send up only one leaf. In really bad years or young plants, there will be no ‘pulpit’ and just a single leaf instead.
