For once, I am going to express my disappointment.
It was an accidental beginning. One fine day, i saw a creeper climbing our wall. I discovered that it was a pumpkin creeper. Since I had not planted it neither had i sown any seeds, I am sure it must have found its way from the kitchen waste. To my utter excitement, it kept growing longer and longer. It flowered everyday, giving more than 10 flowers per day. However, its been more than 2.5 months now and it has not yielded even a single pumpkin. Its thick growth started hampering the other plants, and i was forced to remove the creeper yesterday! I am still wondering why it never bore a pumpkin.
