olive pollen.

Olea europaea · Tree

A spring tree pollen where olives are planted, in California and Arizona.

Usual season in the US

April to June

Typical months; the stronger marks are the usual peak. Seasons shift with region, weather and year.

Where it grows

Olive trees grow in orchards and as landscape trees in California, Arizona and other warm, dry places.

Good to know

Some Southwestern cities restrict planting new fruiting olive trees because of their pollen.

In Sneezecast

Google’s pollen forecast doesn’t list olive for the United States today, and Sneezecast forecasts only the US for now. The app still has its drawing, so every plant the forecast can name has a picture.
