- Plants that avoid self-pollination use various strategies, including123:
- Dioecious plants: These plants have male and female flowers on separate plants.
- Monoecious plants: These plants have separate female and male flowers on the same plant.
- Dichogamous plants: These plants have anthers and stigma that mature at different times.
- Dicliny: These plants have unisexual flowers.
- Herkogamy: These plants have a mechanical barrier between compatible pollen and stigma due to which self-pollination becomes impossible.

Self-pollination - Wikipedia
Both hermaphrodite and monoecious species have the potential for self-pollination leading to self-fertilization unless there is a mechanism to avoid it. 80% of all flowering plants are hermaphroditic, meaning they contain both sexes in the same flower, while 5 percent of plant species are monoecious. The remaining 15% would therefore be dioecious (each plant unisexual). Plants that self-pollinate include several types of orchids, and sunflowers. Dandelions are capable of self-p…
