A Futuristic Hideaway at the San Antonio Botanical Garden
The whole place is worth a visit, but I particularly love this part of the gardens - there are futuristic glass-ceilinged pavilions devoted to cycads, desert, and tropical plants. One room contains culinary plants - think cocoa, tea, cinnamon, and other spices. An outdoor orangerie contains numerous citrus species I'd never heard of.
It's all neatly enclosed by the modestly dramatic architecture - some parts are indoors, some outdoors. It's a wonderful place to get lost in daydreams, and maybe learn a little something about some fascinating plants. Or both.
