Tldr: go for the Japanese garden, or go for a guided tour.

Technically, this botanical garden is great (or that's the impression I got). The exhibits have a wide variety of plants from around the world and the arrangements are aesthetic. When we visited, there was an exhibit which shows how to set up a garden for optimizing water use and another with plants selected to be resistant to arid climates.

Great for horticulturists but boring for us. No context on each plant, just the names. There's a science pyramid with a number of interesting details on plants in the Colorado region but if hadn't visited the mountains themselves, we would have struggled to appreciate it.

There's a lot of promise here, but we left in 2 hours because we found it boring staring cluelessly at plants. Why is this rated so high?
