The winter squash patch is full of bees and blossoms. The photos of the pollen-ladened bees show how they carry pollen from flower to flower inadvertently fertilizing the female fruit with the male pollen while collecting nectar for the hive.
The squash plants have male and female flowers. The female flower is attached to an ovary, that if pollinated will swell into a full-sized winter squash. The male flower is a fruitless rod serving the duty of men the world over.
When we harvest squash blossoms for use in the kitchen we take only the male flower leaving the females to blossom into the fruits of winter.
