Im germinated a bunch of Moonflower datura seeds today (for oranamental purposes and to keep cats out of my grow plot.)
Incredibly lush and beautiful plants with beautiful trumpet shaped flowers. I have thousands of these seeds ive harvested myself.
Cats and dogs generally wont go anywhere near a datura plant, and traditionally, a human taking care of one tends to have much better luck in their gardening practices then if they dont, for whatever reason. Just dont eat the plant, it'll turn on you immediately, and for the rest of your life usually if you do that.
If someone has a PO box, and wants these in their garden warding off pests and small animals, these shoot me a PM. Theyll also pull insect off your fruit bearing plants and onto them, the insects will eat from the datura, and they will die immediately afterward. This is why you see so many insect bites on wild datura's, but almost never see live insect on them, and generally never see any insect damage on near by plants either. There are mite species that can eat datura just fine, but they tend to just stick to the datura.
When my cat walks around these plants, she gives them easily a 12foot gap. She wont go near them. My dogs are straight up scared of them lol. A more beautiful species of plant is hard to find though.
Long story short, the purpose of these plants in a garden is NOT for their psychoactive properties, it's what the plants, as a living organism, are willing to trade you for allowing them a safe place to grow and thrive. Protection, As dumb as that probably sounds.
