The flower began opening at 2:30 pm on the 24th July - by 8:00 pm the spathe was wide open.
Despite the rain, visitors trooped in to see the Titan. This year's bloom is over 190cms - 30 cms taller than the flower that bloomed in 2016.
As well as human visitors, there were lots of flies, fairy bluebirds and a monkey who came to see the opening.
Famous for its distinct odour of rotting flesh, the flower's spectacular smell only began to fade by mid-morning the day after it started to open.
