The first is a scene from Pomarius Nursery. Poncirus trifoliata 'Monstrosa' (also called 'Flying Dragon') twists between two red phormiums, with a pair of Cycas revoluta (sago palm) fronds arching down in the back. I don't think I've ever read anything about the fall color of Poncirus trifoliata even being noteworthy. Isn't it beautiful, though? It seems to color up wonderfully in the PNW. It's not just this specimen. The one in my garden had wonderful color, too, though not quite as orange. I would have included a photo of mine, but it's a much smaller, thinner plant and it didn't have many leaves this summer. Some type of ant was coming out to the edge of the woods where I had planted it and chewing the leaves off to drink the sap. I moved it to a new location this summer, but by then it had stopped producing new foliage. Hopefully, I moved it far enough away from the trees that those particular ants won't find it again.
The second image was taken on a foggy morning at Cistus Nursery. The camera on my phone had a little trouble adjusting to the light. In person, it was ethereal and beautiful (if you like foggy fall mornings, which I adore). The blue-grey foliage of the Eucalyptus perinniana in the background made it fade into the fog around the edges, the oak further back and to the right even more shrouded. The Aesculus californica in the foreground may not have spectacular fall color, but I find the hints of yellow foliage and the structure of the white-barked, lichen and moss encrusted trunks and branches indefinably charming. I plan to add several of these to my garden.
