#1. These are some of my favorites: shown with no irrigation in a parking lot near Petaluma: California Fescue, rudbeckia, lavender, Blue Wildrye, erigeron (probably overused) Sycamore.
some of my favorites from Sonoma County : Echium, Euphorbia amygdaloides robbiae, Flowering Quince, Teucrium, Calycanthus. I think Mondo grass is totally cool. Blue fescue, Umbellularia, Pittosporum tenuifolium (hate all the rest of the pitts – this one is gorgeous) Olive, White Poplar, Caryopteris, I like the mounding of Baccharis, but I don’t like how ratty it gets after maturity, Santolina, most salvias (because they are reliable and tough as nails)
I have no idea if these are ‘unique’ – it depends on how you plant them I think.
#2. no
Most people just don’t notice design – that goes for architecture, interiors, etc. They just don’t see the detail that we are trained to notice. They have to be whacked over the head like Monet’s garden in Giverny. I try to make up for it with volume! ha!
