Weed with prickly seed pod

Oh…thank you Bobbi…do you know if the moonflower is poisonous also?

The Weed of the Month series explores the ecology and history of the common wild plants that most gardeners consider weeds.

The species you are referring to that blooms at night is NOT jimson weed, it’s a moon plant. It is part of the jimson family but not what people will find just growing in their yard in certain areas. Pure jimson weed blooms in the day that’s how you know the difference.

I noticed that the Moonflower and the Jimson flower look much the same, however, the leaves are different. Are they the same plant or just cousins and is the Moonflower also poisonous? My grandmother, Mother and I have all raised them in our gardens in Oklahoma and in Montana….

The genus name Datura comes from the Hindi word for the plant, noteworthy since most botanical names are derived from Latin or Greek. The origins of the plant itself are contested—every source I checked listed a different native origin, ranging from Mexico to India, and it now grows all over the world. Not surprisingly, it has found its way into many cultural and medicinal traditions. Ayurveda, traditional Chinese medicine, and Native American shamanistic practices all employ jimson weed medicinally or ritualistically. Its seeds and leaves are used as an antiasthmatic, antispasmodic, hypnotic, and narcotic.

Jimson weed (Datura stramonium) is a beautiful, witchy plant that begins blooming in late summer and continues through the first frost. A member of the notorious nightshade family, its more famous cousins include tomato, eggplant, pepper, tobacco, and potato. Most members of this plant family are poisonous, and jimson weed is no exception. All parts of the plant are toxic, most particularly the seeds. Potent amounts of alkaloid compounds are present, which potentially cause convulsions, hallucinations, and even death if ingested. And as climate change increases the amount of carbon dioxide in the air, studies have found that the toxicity of plants like jimson weed only increases.

No plant should be wiped from the Earth. They all have purposes, good ones if not misused or over done.
