Figure 9.6 Plant mating strategies. Hermaphroditic plants, such as the Saint-John’s-wort wildflower, possess perfect flowers that contain male and female structures within a single flower. Monoecious plants, such as hazelnut shrubs, have separate male and female flowers, but a single plant possesses both types of flowers. Dioecious plants, such as the white campion wildflower, are comprised of some individuals that only contain male flowers and other individuals that only contain female flowers.
