This is the Tropical Pyramid Glasshouse in the Royal Botanic Gardens Sydney Australia.The gardens are in the CBD and the pyramid house seems to make sense being among the glass buildings nearby. I took this image as part of an entry into an Australia wide competition for Botanic Gardens images. Alas, no cigar for this one but I like it.
Taken in Spring with Jacaranda petals in the foreground.
