Yucca Rostrata peekaboo

Yucca rostrata at a bank? Yep...
I spied these trunking specimens when Andrew and I were headed back from a late spring drive out along the Clackamas River. Coming back into town he made a swing through the drive-thru at Popeye's Fried Chicken—Andrew does love Popeye's—this Wells Fargo branch was across the street. 
I made note and planned to get back to document them, it took me awhile and then it's taken me even longer to finally share the photos, but here we are. Aren't they fabulous all lined up like that?
Of course, being me, I had to take a portrait shot of each one. Here's #1...
#2
#3
And #4
#5's symmetry is off a slight bit, and he's definitely the shortest of the bunch.
Oddly there's a pup at the base. Yucca rostrata don't throw out pups so perhaps a second seed germinated? Perhaps there was a mutation when he was young?

Personally I think it looks like they may be playing peekaboo, leaning out of their little nooks only to lean back in again as soon as I turn my back.
Try as I might I never could catch them in the act.
Well done Wells Fargo, well done.
