About plant names...

Jack-in-the-pulpits are generally between 15-30" (38-76 cm) high. The flowers on this plant are small, in the form of a spadix, a small column with tiny flowers. They are covered by a hood, from which the name is derived.

Identification: The flower spike can be several inches in length, appearing in April to May. The hood (called the spadix) has zebra-like stripes on the inside. The leaves are in groups of three, looking somewhat like poison ivy leaves. The flowers turn to berries that become bright red in the fall.

Edibility: Poisonous. Skull & Crossbones Jack-in-the-pulpit contains calcium oxalate and asparagine. The former causes a burning sensation. A few American Indian cultures may have processed this plant to remove its toxins and consumed it, though.

Normally, the top portion (spadix) is longer, hiding the spathe within. Something isn’t quite right with this plant, so we can peek inside. · 5/27/2016 · Acton Arboretum, Acton, Mass­a­chu­setts
