There's a children's garden there with all sorts of kid-friendly things to do and look at and climb on. On this visit, they were featuring sculptures made of of "found" materials, i.e. old pieces of metal and plastic, re-purposed small tools, etc.
There's a very pretty walled garden
and the Mexican Garden is one of my favorites
And the best thing about gardens is that they are constantly changing. I'm looking forward to our next visit.
