Asparagus Fern flower is glossy, star-shaped, mostly white, and sometimes light pink in color with yellow-orange anthers.

If you maintain the plant in optimum conditions, it can grow for a long time, around ten years.

Similarly, during summer, the flower lasts for about two weeks.

Asparagus Fern Flower Pollination

Asparagus Fern Plant reproduction depends heavily on pollination as it is the only way to survive and evolve.

Typically, plants are either dioecious, where male and female parts are on different plants, or monoecious, where both male and female are on the same.

Also, the flowers can be hermaphroditic and have male and female reproductive parts in the same flower.

Recent research suggests that most African Asparagus Ferns typically have hermaphroditic flowers, unlike most Eurasian species, which are dioecious.

For the Asparagus Fern flower to pollinate, a honeybee or other external pollinators must visit both the male and female plants. After pollination, plants produce seeds through which they germinate.

Female flowers produce little round berries with a diameter of up to 1/4 inch. The green fruits turn glossy red on maturity; each contains one to three black seeds.

Since many birds are attracted to the fruits, they unintentionally spread seeds. These seeds then take around four to six weeks to germinate.
