The California University system provides me with 3 botanical gardens all within reasonable driving distance. This year, I have had to postpone my annual spring road trip due to unexpected business commitments, so last weekend I took a 48 hour whirlwind tour to the central coast to visit the UC Santa Cruz Arboretum. This is a great winter garden; the Proteas, Banksias and Grevillias are all in bloom, and their collections of these genera are impressive.
Unfortunately, the tags were hard to find, and I was intent on photos. Wish I had some better ID info to share.
