Answer: Fruitless olive trees are immensely popular because they produce no (or very little) pollen and do not litter the ground with fruit. They can be quite large at maturity, though, so you might want to investigate 'Little Ollie', a large shrub or small tree, rather than 'Majestic Beauty', which is a large tree at maturity. In a small planting space the roots of a full grown olive tree can be problematic. Olive trees do not require annual pruning but you can control the size to some degree by pruning them back occasionally. They are quite adaptable to may soil types and the spacing from buildings, etc. will depend upon the cultivar you choose.
There are a number of fruitless olive trees available and they deserve some consideration:
Introduced in 1961. Less popular than the others. Not really fruitless, but has tiny fruit (like privet's).
Introduced in 1987. It's a big, dense shrub, very dark green, excellent as a hedge or screen. Bears almost no fruit.
Introduced in 1985. Airy- and fluffy-looking, it's also suitable for a hedge or screen. Bears almost no fruit.
Introduced in 1969. Typically a multiple-trunked, large, compact shrub. Sets a very small crop some years.
From Swan Hill, Victoria, Australia. Introduced to California and Arizona nurseries in 1972. Its leaves are a deep green. Bears no fruit.
Introduced in 1979. It was discovered in a grove of Manzanillo olives. Bears no fruit.
