The University of California at Santa Cruz Arboretum is a gem containing a huge collection of plants from representatives of more than 300 plant families of Mediterranean climates — specifically Australia, New Zealand, South Africa, and California — a climate characterized by dry summers and mild, wet winters.
I encountered a bit of a surprise on the last little part of my walkabout at the University of California Santa Cruz Arboretum — plants that I would not associate with a Mediterranean climate. They look to me to be more at home in a desert. They will indeed grow in California (otherwise they would not have survived here at the western base of the Santa Cruz Mountains) but I think of them as more Arizonan. But what do I know after a long career in computers and a retirement career in photography.
This show plant is the deltoid-leaved dew plant (Oscularia deltoides) which is a succulent native to South Africa. According to Wikipedia, the flowers sprout in spring, dispersing an almond scent. I did not smell any such aroma so it must have been past their peak.
