Look the bright yellow color of the pare flowers...
There are male and female flower on the same vine.
The flower blooms on the afternoon until the morning time.
It has a good smell, soft-sweet fragrance.
The picture below is a male flower.
And this one is female flower with the little fruit set below.
Look the difference...
The male flower is much more than the female flower.
The female flower is about 10-20 percents from total flowers on the vine.
When the pollination is success, the fruit will be formed.
The first flower bears on the second month after planting.
Next, we will talk about the fruit.
