Passionvine

Passion flowers are so pretty. And unusual. Great vine for the garden. And the Gulf Fritillaries lay their eggs on it. So you get butterflies, too, if you are within their range.

But in addition, you can buy passionflower extracts to help decrease insomnia or anxiety. There is some evidence that it is effective. It can also cause hallucinations and psychosis in large doses.

But don't use garden plants as a sleep aid. Some species have cyanide in them. So some are more toxic than others.
