How do we know? Because Annie Wang sent these pictures.
We went there in 2004, Annie was our guide. You can see a film about it on the Bach Educational Resource: http://bacheducationalresource.org/r/i/flowers/3 scroll down the page to ‘Discovering the flowers’ section
And play the film Searching for Cerato.
You can also view a time-lapse of the flowers opening.
