Jack in The Pulpit (Arisaema triphyllum) - Interesting facts
Jack in the Pulpit got its name from the shape of its inflorescence of flowers. The inflorescence has two parts, the spadix and spathe. The spathe wraps around the spadix and resembles a pulpit. The spadix sits in the center of the so-called "pulpit" much like a priest giving a sermon.All members of the Arisaema genus are poisonous if ingested. Historical lore states that the Meskwaki Indians would chop up the underground corm of the plant and mix it with flavored meat. They would then leave the poisoned meat in a place where their enemies would likely find it. If eaten, it is said to cause tremendous pain and eventual death.
Jack in The Pulpit (Arisaema triphyllum) - Soil and irrigation
Does best in moist, but well-drained soils. When the plant goes dormant the plant's demand for water decreases, but do not allow the underground roots and stems to dry out. Water freely when it is actively growing.
