Probably one of the best botanic gardens I've been to. It has many different species and almost rivals the Chicago botanic gardens.
The price is steep to me. The layout of the gardens makes it an enjoyable walk and is pretty easy to navigate. It's like one big loop with 4 other loops branching off the main one. Each has something slightly different but towards the end there are only so many cacti you want to see!
Of course, there were aloe and agave plants as well and it was laid out and maintained well.
This is another place to wile away a half day, possibly not so much if it was really hot but the weather was perfect for us in Feb.
Who knew the plants could be sooooo big!
