The flower is beautiful and can grow up to 20 to 50 centimeters.
Aristolochia grandiflora uses the not so nice scent to attract its pollinators.
The pollination process is very special.
The pollinators are held in the calyx of the flower for two days.
The first day the flower is in the female state.
In this condition, the pollinators pollinate the pistils.
The second day the flower changes to the male state.
The pollinators are dusted with pollen in this state and released again.
After this pollination, the flower fades and the fruits are formed.
