Pollination Information for Portuguese Laurel (Prunus lusitanica)

Portuguese Laurel is a self-fertile plant, which means that it can produce fruit without needing pollen from another plant. However, cross-pollination can increase fruit yield and quality.

The flowers of Portuguese Laurel are hermaphroditic, which means that they have both male and female reproductive organs. The flowers are pollinated by bees and other insects that are attracted to the bright white flowers in the spring.

The pollen of Portuguese Laurel is heavy and sticky, which makes it less likely to be carried by wind. Instead, it relies on insects to transfer the pollen from the male reproductive organ (the stamen) to the female reproductive organ (the stigma).

It is recommended to plant at least two Portuguese Laurel plants in close proximity to encourage cross-pollination and increase fruit yield.
