Chestnut Tree

Flowers
Unlike other plant species with flowers housing both male and female reproductive parts, chestnut trees grow two distinctively different flower types. Referred to as catkins, chestnut flower heads develop as male, pollen-producing structures at the beginning of the summer. As the season progresses, the tree creates bisexual flower heads. These flowers, having both male and female reproductive parts, allow pollen to fertilize their structures for nut development.
