Wow! My head is still spinning from visiting this botanical garden (it is in No Cal in Glen Ellen, which is near Sonoma) and a attending a talk there by Dr. Wong, who is the foremost expert on old Chinese roses in China.
I had never been to the garden, and knew nothing about it. It turns out that it is located on land that used to have a quarry (duh), so there is a beautiful little lake, and the garden is hilly, with fabulous views. We got there about an hour before the talk, and just wandered around the garden. Looking at the plant labels, I noticed that they ALL appeared to be from China. Turns out that the whole garden is a collection of plants brought back (I think mostly as seeds) from China over the last several decades, propagated, and planted. Amazing. There were species roses that I didn't realize were roses (some had only 3 leaves, some looked like ferns, etc)!
Anyway, if you can get there run, do not walk.
Dr. Wang's speech was amazing - he has been discovering/re-discovering species roses and hybrids from 1,000 years ago in China - including ones that folks thought no longer existed. He is writing a book, and I want it, I want it! I feel like I did when the tea rose ladies from Australia came over here and told everyone about their book - I almost burst waiting the next 5 years until it came out, but it was worth it.
