Very unusual is right. Never saw anything like it.

I have seeds. Kat from Amlo Farms sent me a slew of them. I tried germinating them this spring, and failed. I'm going to be trying again next year. I assume it will be an annual here. She's in Austin, TX.

It has been a "few" years, but I remember a neighbor growing one.
That was in Pharr, TX, which is on the TX Mexico border.
Very unique.

Wow is that weird! Lol very pretty , ive never seen anything like it.

It is suppose to attract a certain type of butterfly.

Pipevine swallowtails.
