| 説明 | Arisaema triphyllum I know this plant as Jack-in-the-pulpit but it's also known as Bog onion, Brown dragon, Indian turnip, American wake robin, or Wild turnip. The plant is a herbaceous and perennial. It grows from a corm.Supposedly it is a highly variable species typically growing from 30 to 65 cm in height. The ones in my back yard are about 12 in. or 30 cm. Each stem has three leaves but do not confuse Jack with Poison Ivy. The 'pulpit,' or spathe, of my specimens are green, with white stripes, but the stripes could also be brown or purple in specimens elsewhere. The 'minister,' or spadix, is a pale creamy-green spike inside. It's native to eastern North American moist woodlands as far north as Nova Scotia, west to Minnesota, and south to southern Florida.WARNING:Jack-in-the-pulpits contains needle shaped crystals of calcium oxalate called raphides in all of its parts. Ingesting even tiny amounts of this chemical by eating the plant can deliver a vigorous burning sensation, irritating the mouth and digestive system. If swelling of the mouth and throat is severe enough, breathing could be affected. Calcium oxalate, in small doses will cause intense discomfort but it is usually short lived complete recovery is the norm. In larger doses, however, it can cause severe digestive upset, convulsions, coma, and even death. Recovery may leave behind permanent liver and kidney damage. The crystals are known to form stones in the kidney and you'll wish you were dead as you pass them.I'm sure the effect of this plant on animals and pets would be similar to that of humans, however, my dogs give this plant a wide berth and to my knowledge have never been affected by it. My squirrels are content to feast on my daffodil bulbs and leave Jack's corms alone.The specimen I've pictured is a female. She will be about the business of making a clump of bright red berries that the native Americans called a “fire ball!” Not sure if the name comes from their fire engine red color or the burn they deliver when you eat them? I'll try to get a picture of a "fireball" later in the season.If the plant is properly dried or cooked it 'can' be eaten as a root vegetable. The internet is filled with goofy recipes that I have never tried, and am unlikely to ever do so. |
