Pollination

When planning your edible landscape or wildlife habitat, it is important to consider the subject of pollination.  Without proper pollination, fruits and seeds will not be created.  Some species of plants are self-pollinating because each individual plant produces both male and female flowers or flowers that contain both male and female parts.  Such species are termed monoecious.  Among monoecious species, some require a second individual plant of the same species (but generally of a different variety within that species) to be present for cross-pollination in order to set fruit.  For example, in order for an Anna apple flower to grow into a fruit, it needs to be cross-pollinated with pollen from a Dorsett Golden flower or any other apple variety that blooms concurrently.

Most plants fall into the “monoecious” category, but some of the species we offer are dioecious.  In dioecious species an individual plant is either male or female.  In order for these species to fruit or create viable seed, it is necessary that both a male and female be present.  A single male plant generally provides enough pollen to accommodate several females.  This is not to be confused with cross-pollination, which involves pollen from one variety fertilizing the ovary of a flower of a second variety.  Among dioecious species, some can also be “polygamo,” which means that while an individual plant primarily produces either male or female flowers, that individual can also produce some “perfect” (male and female) flowers which are able to self-pollinate.
