I sowed a package of wildflower seeds last spring. In the mix was included some annuals as well as some unnamed perennials. Now that the annuals and wildflowers are ending their show I have some plants left that are unlike the weeds I normally have in my yard. They have not flowered this year, so I am assuming they are going to flower next year. If I am wrong and these are weeds I would like to know. Thanks in advance for your attention.
Since it is common and looks like that the stuff smothering the blanket flowers and cone-flower will probably turn out to be Oenothera x glazioviana.
Put into European commerce in 1860, this is a hybrid of uncertain origin - most likely O. elata ssp. Hookeri x O. biennis - A.L. Jacobson, Wild Plants of Greater Seattle - Second Edition (2008)
Thank you, thank you Your knowledge is very appreciated. I am so happy to know this. These ladies then are growing in the wrong place -- TOO TALL. I will move them this fall. No ideas what the first pic is yet --- could it be the same as in this recent post ? My leaves are moreso pointed though --- but I wonders http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=80597
The Oenothera probably won't transplant very well, you might want to move the others out from under them instead. The O. is a biennial that makes a rosette one year and then flowers the next, peters out. Once it comes onto a place it may persist for years, by reseeding and popping up here and there. If you decide you want to eliminate it keep it from going to seed.
" may be a hybrid" , "probably a hybrid", it is what I was able to find on the Net (and " a hybrid of uncertain origin" in your post). Could you give a few examples of the use of Oenothera x glazioviana on the Net ?
Suggest you contact Jacobson directly and ask him about it. Contact link is on his web site. He responds to all polite queries.
Both ITIS and The Plant List consider it to be a valid species: http://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=27401
