Here's something interesting though. The pond in the courtyard has water lilies that make huge root masses that, in turn, collect dirt. Things grow in that mass. Here's a photo of two oleander bushes that sprouted in the pond. I have pink varieties growing nearby, but I've no idea where the white one came from.

And here's that Prickly Pear blooming over the septic tank leech-field.
