Do you recognize the spotted jelly-like blob on the lower right leaf of this Turtlehead (Chelone glabra) plant? If so (or even if you want to make a wild guess), go to the Naturally Curious blog (www.naturallycuriouswithmaryholland.wordpress.com), scroll down and click on “Comments” to submit your entry. Look for the answer in the next Naturally Curious post. (Hint: Turtlehead likes its feet damp.)

Turtlehead, Chelone glabra, a member of the Plantain family (Plantaginaceae), can be found growing along stream banks and wetlands throughout eastern North America. Its long arching upper lip, or hood, overlaps the lower lip like a turtle’s beak, giving Turtlehead its common name. The male parts of the flower mature before the female parts, and when pollen is being produced these lips are very hard to pry open. Pollinators are primarily bumblebees, which are some of the only insects that have the strength to open the flower. When the female pistil matures, the lips relax a bit, so entry is easier, but access to the nectar at the base of the flower is restricted (by a sterile stamen) to long-tongued insects. Thus, it is specifically long-tongued bumblebees that are able to both enter the flower and to reach the nectar. If you look on the sides of the flowers, occasionally you will find where impatient bumblebees have chewed through to the nectar, avoiding the struggles involved in entering the flower in the traditional manner.

Turtlehead, Chelone glabra, is named for the flower’s resemblance to the head of a turtle. These flowers are pollinated by bumblebees, which crawl in between vertically-paired petals causing them to open, much like a turtle’s jaws. Ruby-throated hummingbirds are also attracted to this flower. After pollination has taken place, the ovary swells and forms capsules which open to release flat, brown seeds. To my eye, the seed capsules that persist through the winter bear even more similarity to this plant’s namesake than the flowers. Look for these seedheads near wetlands, floodplains, marshes and springs.
