The largest flower in the world only blooms for three days every seven years, but when it does, it's a spectacular and rather smelly occasion.
Not for nothing is it known as the "corpse flower".
You can find it in the rainforests of southern Sumatra.
The growth rate is phenomenal, three inches a day at its peak, with the stem rising from an underground tuber to a height of 10ft or more.
The fishy smell seemed to come in waves - we now know it attracts a species of bees that fertilise the plant.
With these rare plants often separated by several miles, the smell has to be strong to attract the bees to it.
