Backyard and Beyond

Starting out from Brooklyn, an amateur naturalist explores our world.

As John Burroughs said, “The place to observe nature is where you are.”

Don’t Know Jack?

Someone hath browsed off the overhanging spathes and tips of the spadicies of these Jack-in-the-pulpits (Arisaema triphyllum). This gives us a good view of the pin-striped goodness within these curious flowers.Otherwise you have to get personal.This is a flower that hides itself.Who is this Jack, you might well ask, and what is he doing in the pulpit? To say the spadix “looks like a man,” as does Better Homes & Gardens, seems quite the euphemism. The part is not the whole. According to this site, the plant is pollinated by fungus gnats and thrips. Also of note on that page: the ill-tasting plant scares off herbivores, so who did the work seen up top? Two legged? Deer not yet in the know?

  1. Ah, but in this case, it DOES represent the man, since it’s supposed to be a clergyman (?) in the pulpit. Though I never knew why he was called Jack.

    1. Bit of a pinhead, isn’t he?

      1. Certainly doesn’t show much expression – though he is very upright.

    Hmm. I have Jacks all over my woods and now in my front porch garden. Which means I must have fungus gnats and thrips? What are they, exactly?

    1. Tiny insects. The gnats are members of the Diptera (flies); and thrips are in the order Thysanoptera — most under a millimeter in length. I don’t recall ever running into a thrip, but there out there somewhere.
