Any idea on the botanical name?

No, thats what i am looking for...thought maybe someone would have heard of it.

I could not find any plant by that name. What about Twisted Evening Primrose, which is Oenothera odorata? It is however, native to Southern South America. In any case, I thought the common names were somewhat similar. ;)

Good luck!

I agree, I think your seeds are a type of Oenothera.

Check out the GardenWeb link below where someone is discussing a plant with the same name:

Here's a New York Times article where a botanist discusses his "spinning primrose":

"CUTTINGS; Frumps by Day, but Fragrant Jezebels by Night":

Here's a YouTube video called "Spinning Primrose". The flower is listed as an Oenothera:

This website for the Twin Oaks RV Park & Campground in Elko, Georgia features a photo of residents who gather together every evening to watch a "Spinning Persian Primrose" open:

Apparently during the blooming season, the flowers open at the same time every night. From the looks of the photo, the plant seems to spread a lot under optimal conditions.

Thank you so much for those links, that is a great lead to figuring this out! I really really really appreciate your help.

I will post some pictures if I get some flowers next summer - maybe a video of them opening up.

I know exactly what you are talking about. Spinning Persian Primrose is awesome. I have some seeds and am trying to get it to take off again. We had it for years passing it among family, but mine has died off. Each plant only stays for two years. The first year it comes up looking like a very healthy dandelion. The next spring it will sprout right out of the middle and grow straight up, and when it get ready to bloom you will see the buds during the late afternoon get little white pistols coming from the end of the bloom. Then right around 8:15, the bloom will quiver, then right before your eyes it will slowly open. I say slowly, but it actually only takes about 10 seconds per bloom. The plant will bush out to be sometimes 3 feet wide and 3 feet tall. with maybe 40 or 50 blooms. My Grandmother lived in a retirement village, in her own home. She had three plants in a bed on the side of her home. Word got around and she would have neighbors coming each evening carrying their lawn chairs to watch the flowers open. If you ever find them get them. I am still looking for plants, but still trying to get these darn seed to grow.
