  1. DO NOT GROW THIS! It is a deadly poison. The lethal dose is very close to the hallucinogenic dose. It is the famous ‘loco weed’, causing disorientation in cattle and horses, who may stampede and cause injury. It can kill children who eat some. Get another hallucinogen if that is what you want.
    DO NOT USE IT FOR MEDICINE if you are not a doctor or licenced, trained professional of the sort who can measure the doses and treat any overdoses. I don’t even know if OD can be treated.
    DANGER, better to leave this one alone.

  2. They all have beautiful flowers ,some species more than others . No one should ever ingest this plant for any reason unless you know what you’re doing.It can kill you.

  3. Thanks for the info! I’m going to throw my seeds in the ground this weekend and hope it grows. Ya its toxic but great for sphinx moths!

    • I just picked up some of the thorny pods, I assume that’s the seeds. Did yours grow! Did you bury the pod or just leave it on top the ground?

      • The seeds are inside the thorny pod – when fully ripe it dries & splits open; the seeds are about the size and color of morning glory seed.

    • i’m growing the double purple daturas and double yellow, also white doubles; not concerned with eating them; i just want to enjoy the spectacular blooms. Also, i’m always trying to get more hummingbird action and i’ve heard that they will eagerly flock to datura flowers.

  4. This is a medicinal herb great for allergies, for example. It is not dangerous if you titrate the dose slowly or unless you’re deliberately eating it to trip.

  5. There were some big ones growing in our dog’s pen (we left them because we thought the flowers were pretty).

    TOTALLY NOT WORTH IT! My beautiful German Shepard ate some seeds and nearly died. He spent a weeks at the vet just lying in his side nearly paralyzed until his body was able to flush the toxins from his system.

    When I pulled the plants up some of the seed pods poked me in the arm and it burned for days.

    Do not recommend keeping this plant for any reason, not worth the risk to you or others that might come in contact

  6. Silly fearmongerers. Know what you grow, and if it happens to be a moderately poisonous plant like Datura, be aware that it can cause some rather unpleasant effects if not handled with appropriate care.
    You would have to ingest quite large amounts to actually cause serious harm to your body, difficult partly due to the nauseating taste of the leaves.
    That said, it could most certainly cause some unwanted effects on your mind, even in smaller doses or from handling the plant without proper precautions. That however is not the plant’s fault. Some people actually seek those effects deliberately.
    The plant is very beautiful, easy to grow and maintain.
    There is no need to tell people to stay away from it and spread unnecessary fear (written with CAPS locked, smh).
    As general advice one should reconsider growing any poisonous plants if you have kids or pets around, but otherwise it boils down to proper handling and care. It’s just an ornamental plant, not the devil himself.

  7. I planted a 6” seedling in June and got a 6’ gorgeous plant that produced about 8 new purple and whte flowers every day. The plant wilted with the past few nights’ 30º temps (zone 7), so I cut it down and harvested the 20 or so seeds that have been developing on the plant since August. They’re walnut-like, smooth, not spiky, and still green. Plantable for next year? How to store? I have photos if you would like.
    Would love any advice, please.

  8. Great plant for the flower garden. Multiple huge white flowers pollinator love. Don’t eat the plant or any part of it. If your dog unfortunately resides in a pen (like the above owner) always check what plants inhabit his meager living arrangements and remove if questionable. You will love this plant. Cool seed pods. I planted some in a pot to make sure I have more for the next year. Sept 2020 – germinated and grew to planting size by March, 2021.

  9. This is the only plant that I have actually witness a sound when it blooms! The blooms are quite large and the petals tear apart, making a kissing sound! They smell terrific.
