I'm not positive but the artist chihuly (something like that) does ring a bell...inside the Climatron is a display of same artist's glass flowers. Mobot has more glass works (assuming same artist) This is entrance/exit to the rose garden.
As seen through a conservatory window -
There are 3 aligned lily ponds in front of the Climatron; in one float these tapered glass sphereicals -
Lily pads were quite as impressive as the blooms.
Extended view.
