The gardens are billed as 5.5 acres, and 5 separate garden styles, and I thought that they would take up more of the day that they did. It is possible that a more leisurely walk through would be possible if you go with just your honey. Not so much with your honey and a twelve year old, for whom life is about what is next. Always, what is next. I tried to explain about the Zen. Twelve is not a very Zen age. The gardens have Zen covered though.
After the gardens we walked over to the rose test gardens which are equally stunning in a pleasantly down the rabbit hole kind of a way. They are also free, which is nice, and judging by the lots of people, seem to be The Place To Be in Portland on a sunny Saturday afternoon.
