Thanks for that tip. Which one of the 3 seeds can become invasive?
Oenothera Caespitosa White
Oenothera Caespitosa Flava ssp YELLOW (I have some of these already)
Oenothera Speciosa PINK

I transplanted them from the pots that the seeds started in, to my garden today.
If they become invasive will just have to either transplant or pull them out.
I do find that most all plants can be invasive - or propagate where you don't want to to.

See pictures of what they look like in bloom.
