Individuals of other species are both male and female, including some that can self-fertilize.
These plants produce nonfunctional pollen and, consequently, are unable to self-fertilize.
Species in which isolated individuals can self-fertilize are generally good colonists.
Although it can self-fertilize, it requires a pollen vector.
A fraction r of the individuals self-fertilize, the remaining (1kr) reproducing through complete outcrossing.
Depending upon conditions, garlic mustard flowers either self-fertilize or are cross-pollinated by a variety of insects.
There are cleistogamous flowers, which self-fertilize and never open, and chasmogamous flowers, which open and receive pollen from other plants.
