Was she a stoner? Those sound like high asf thoughts 💭
My (adult) son once asked his brother what plant salt grows on when he was high. He's the "smarter," older brother, too. He will never be allowed to live it down.
It grows in kale. If you have soil fouled by salt, you can grow kale on it to suck it up into its body and fix the soil.
I'll let him know! Lol
