Flowers of the olive tree, which are small and whitish, are difficult to see behind the evergreen leaves. Olive trees produce both perfect flowers, with male and female reproductive organs, and staminates that contain only stamens. Olive trees do not need insects for pollination, only wind, and most varieties are self-pollinating. Cross-pollination, the practice of planting more than one olive tree to ensure pollination, is not necessary but it does produce more desirable fruit.

They grow on small olive trees. Anything edible such as apples, pears, nuts (a hard-shelled fruit) that contain seeds or a pit is a fruit.
Eucalyptus trees produce a small gumnut which is only edible to certain animals and birds with strong beaks, such as cockatoos.
Fruit trees, mostly plus olive and date trees.
Olive trees can produce olives for approximately 100 years, but they can live longer than that.
Fruits
Apple trees produce apple blossoms, which when pollinated, then produce the fruit. Only trees with needles produce cones with seeds, some of which are edible, but not as fruit -- as nuts.
no trees exist that don't produce flowers but produce fruit
The type of cultivar of olive you are growing will determine how long it takes for the olive to bear fruit. The Arbequina and Koroneiki cultivars bear fruit after approximately 3 years, while other cultivars often do not bear fruit until they are 5 to 12 years old.
Orchards are groups of fruit trees, so the produce fruit, therefore they produce seeds.
Apple trees produce fruit once a year. Different varieties mature at different times.
