Pampas puzzler

Here’s a photo of some pampas grass (Cortaderia selloana), much beloved by many homeowners in their landscapes:

But what’s unusual – and undesirable – about this particular specimen?  Hint:  the landscape has been modified a little.

  1. Usually these posts are much more puzzling to me. I looked at the image and before I read the text my brain said “that’s feral pampas grass.” It grows all over the place in California as an invasive weed.

  2. Has it been sprayed in an attempt to kill it, which obviously hasn’t worked, and is now not likely to work again due its current sickly state? It’s my experience with pampas that unless you thoroughly kill it with a spray the first time, the plant continues growing in a sickly state, which makes it virtually impossible to kill with herbicides in the future (i.e. spraying unhealthy plants with herbicide will often not kill them as they do not ‘take it up’ as readily as healthy plants do).

  3. Hmmm – well, it is invasive, but that’s not unusual. It’s half dead – did it get sprayed with herbicide & still not die completely ? Or is it that it’s smack in the middle of a restoration meadow ? Or … perhaps it’s in the middle of a wilderness area (evergreens in the background + the obvious slope = limited access mountains in my area), far removed from its parent ?

    I’m sure the answer will be obvious once we have it, but those are the thoughts that come to my untrained eye.
