Any time I travel, I try to hit up whatever garden or other type of conservatory that the city may have to offer. I have yet to regret making this decision and in turn, have seen some of mother nature's most incredible creations.
This radiating purple water lily was seen in the Conservatory of Flowers - Golden Gate Park, San Francisco, CA. I highly recommend visiting if you have never been. It's fairly small, but what is there is beautiful.

These two rare finds were also in the Conservatory. I wish I could remember the names. If anyone knows, please feel free to share.
