Wow! This is a photographer's dream come true. They have everything here. You can walk it in about 1 1/2 to 2 hours but could spend much longer if you wish to see everything. There is an entire section with redwood growth (which they built the gardens around). The history is fascinating. There is plant life from all over the world represented. Well-marked paths, well-labeled foliage and a beautiful stroll on a warm day. A must-see for anyone interested in plants of the world and/or photography of nature.
