Is this Ozark Sundrop?

(Zone 4b)

This flower caught my eye when walking by a church this past June; very attractive flowers.

Doing some looking on the web I *think* it is "Ozark Sundrop" (or could it be Oenothera fremontii "Shimmer"). What do you think?

What has your experience been with this plant (I am zone 5)?

Yes, it is a Ozark Sundrop. I recognize it because a neighbor had it, and regretted it. It is a very vigorous grower than some descrice s invasive, especially in good soil. It grows a very large taproot and is difficult to divide or relocate. Perhaps in pots?

Have a look:

Thanks Donna. I have seen conflicting reports re its "invasiveness". But you did get me thinking and doing some more searching. Specifically it seems that Oenothera fremontii "Shimmer" or "Lemon Silver" looks very similar but with 'better' foliage and (much) better behaved.

That sounds good. A lot of invasive plants have gentler cousins, or are gentler in more demanding soil. It really is a lovely plant.
