Catching up on a few drive-by gardens

Today's post features a few places I've stopped to take photos of, but that didn't warrant a full blog post all their own (they're worthy, I just don't have enough photos). First up the Pat Calvert Greenhouse at the UW Arboretum. I did a quick look-see back in July during the last day of the Fling. You never know what you might find for sale there, plus it's fun to keep an eye on the garden.The ginormous gunnera, shaggy palms...
... and recovering cordylines. Unlike the ones I showed last Friday (that are only sprouting at the base), these are also growing further up the chunky trunk.
I have no idea why this plant/pot needed to be chained to the greenhouse structure, but it must be valuable in someone's eyes.
Now we're in Portland, where I happened upon this row of Agave ovatifolia when I turned on a random side street to avoid traffic. Score!
Five sexy agaves all in a row (with a nice Yucca rostrata in the background). I have to wonder, were there more agaves in the empty spots that didn't make it?
The spacing seems like that may have been the case.
Full-frontal shot.
Back up in Seattle now, after visiting my friend Scott's garden (post forthcoming) he took me to see this nice commercial planting. 
That healthy Yucca rostrata with the chunky trunk must have bloomed or endured some sort of trauma because it now has several growing points, I think we counted at least five. Behind it is a blooming crepe myrtle...
... and just a little further down the sidewalk an extremely happy mass of opuntia. Look at all that fruit! It must have been incredible in bloom.
And speaking of fruit, there's also a pomegranate with full-size fruit.
Pulled back view.
And including the narrow hellstrip.
