Flowers: The flower is a funnel-shaped, fragrant bloom that grows up to 4 to 6 inches long but may grow as long as 10 inches. Inside the spathe, you can see the tiny, true flowers on the narrow spadix or flower spike.
Fruit/seed: Fruits are approximately 13 x 10 mm. The fruit ripens from the tip to the base and becomes bright orange.
Seed dispersal: The Calla Lily relies on birds eating the fruit for dispersal of their seeds.
Pollination: Calla Lilies are not capable of self-fertilizing, it requires two different plants to form a viable offspring. The pollen is extruded through the anther pores it can be spread in many ways, the most popular way for the plant to spread pollen is to attach it to the smooth hard back of many insects most commonly the beetle. After the beetle has had pollen attached to it from one plant, the beetle will travel to another spathe of another Calla Lily for food or shelter and by doing so they accidentally participate in an act of pollination.
