It was great even in late September
If you're looking for Times the roses are blooming, May through September are generally good. After September, it will depend on weather and the garden caretakers schedule as to whether there are any blooms are left. As mentioned, the Japanese gardens are also a great place to visit - at any time of year.
May through Sept
Planning on being there mid May. Japanese gardens also
Anytime in the summer is great
Early June was great when we were there.
Is there all in bloom right now?
I was there in august and it was lovely
I have found that the best time to visit the gardens is on Fall evenings after a light sprinkle of rain...
Early fall
