I've been in the Bay Area the last couple days and have seen some beautiful plants! One that stuck out to me was Rosa moyesii. The hips are just amazing in person. It almost looked like a Pomegranate from a distance, but as I approached I realized it had to be a rose.
As far as I can recall, Campanula is the most vocal supporter of Rosa moyesii on this board and I don't blame her at all! What a beautiful species rose. So much interest without a flower in sight.
And for good measure, the lovely Reve d'Or at the SF Botanical Garden's main entrance.
