I'm pretty sure that's it,! Oenothera macrocarpa...according to the pic. According to the article Remy linked to, This species is a perennial with a fairly short bloom period. Its flowers may be seen in May and June, with the peak being mid-May in Kansas. Like I said b4...mine blooms off and on all season, and is a real favorite. I am clueless where it even came from. Thank you everyone. You all are the bestest and so knowledgeable. I refer lots of folks over here, telling them someone can most likely help them with an identity, even with just a good description. Sue...happy to have that solved.

thanks for all the feedback, also, thanks for teaching me how to post pictures. ya i got that bleeding from home depot and it was only about a foot and it didjnt do to well last year but like most of my perennials, they do much better their second year. i also have a white flowering one which is just blooming now after the pink one died. its great how that works out :) ill also get a lot more pics of my clematis which has worked their way up to the total top of our tree house which has to be about 10 ft or more. and now they are going to bloom and their has to be around 50 buds so im being patient. also when my dahlias and gladiouluses actually bloom ill get pictures of those too.

Hi Carol, Excellent, thank you so much for your help. I have a cutting and I hope is strikes. Merry Christmas Ken

Thanks for the replies. We have Coreopsis here but this one is different or at least a different variety. This little flower usually has only one bloom per plant and is only about 4 inches tall. The flower is less than an inch in diameter. I will research it some more, and let you all know what I find. Kt
