Oenothera berlandieri. "Siskiyou"

I'll pop in with a few thoughts on Oenothera berlandieri. I agree with
Kurt that shade controls it. Some gardeners may find that necessary. A
friend of mine calls it "a beast," but I like plants that have invasive
tendencies. It's damn hard to grow stuff in the Sierra Nevada foothills!
I've got mine under control in a spot under an oak tree that gets only
mid- to late-afternoon sun, but it takes the intense heat there. I give
it minimal water. As Kurt has noted, it's becoming a popular plant for
parking lot landscaping and median strips because it is truly a
showstopper in late spring/early summer in areas that are tough to grow
anything.

The flowers are great to combine with other pinks and bright yellows:
I've got mine near phlomis fruticosa, a bright pink dianthus and
Zauschneria californica "Solidarity Pink."

I believe that O. berlanieri "Siskiyou" is an introduction of Siskiyou
Rare Plant Nursery in Oregon, but I could be mistaken.
