Here is my mystery white flower again. I posted an old picture of this earlier this year and we never really came up with an ID. This picture was taken this morning. I'm not positive if I planted this .... or it just popped up from the ground. Either way I like it. It's flowers close up in the heat of the day. It resembles a silene or perhaps a lychnis but I still haven't nailed it. Anyone have any ideas.
SOLVED: Unknown white flower
Thanks Jersyguy. Your guess led me to the correct answer. This plant is too big to be s.maritima vulgaris. It grows 2 feet tall. From my search I think it's simply white campion or silene alba. http://www.css.msu.edu/css402/whitecampion/whitecampion.htm I've never been able to collect seed from this guy and have always figured it must have separate male & female flowers for pollination. Thanks for the help!
