Have You Noticed the California Fan Palm Fruit?

First off, what does this fruit look like?

Of course the flowers are needed to begin producing fruit. Numerous branching flower clusters grow out amidst the crown starting in early spring. Producing variable white to off-white or cream-colored flowers. Once flowers are pollinated, fruits begin developing in early summer.

The red-black fruit is classified as a drupe. Meaning they contain a single seed surrounded by fleshy pulp (think of a peach or plum) & don't split open when ripe. The California Fan Palm Tree has hard seeds, taking up about half the inner contents.

California Fan Palm trees produce round or oblong small fruits. Typically measuring close to 1/2 inch (1.3cm). They show themselves in multiply branched clusters, kind-of like grapes do.
