Arbosana I-43 Olive

Olea europaea ‘Arbosana’

A dwarf olive with big crops of small olives, rich in premium oil with a more robust, balanced flavor than Arbequina. It ripens about three weeks after Arbequina and is less cold hardy, so keep it in the low desert and out of frost pockets. Pair it with Arbequina for heavier crops and check city pollen rules first.

Chill hours: 200–300 chill hours
Harvest: November to December in the low desert
Pollination: Self-fruitful; heavier crops with Arbequina nearby
Mature size: 10–15 ft unpruned (dwarf); easy to hold at 8 ft
Cold hardiness: Cover while young. Dave Wilson calls it moderately frost hardy, but UC tentatively lists it with the cold-sensitive olives. Olives are often hurt at 20°F or below, so cover young trees in a hard freeze. Green fruit can be damaged near 28°F.
Heat tolerance: Takes full sun and heat. Compact and heat tolerant, fine in full sun. Fruit ripens about three weeks after Arbequina. Paint young trunks white.

	A dwarf olive with big crops of small olives, rich in premium oil with a more robust, balanced flavor than Arbequina. It ripens about three weeks after Arbequina and is less cold hardy, so keep it in the low desert and out of frost pockets. Pair it with Arbequina for heavier crops and check city pollen rules first.	Small, mild, fruity olives with very little bitterness and a high oil content, from a compact tree that is moderately frost hardy. Self-fruitful but heavier with Arbosana nearby. Best in the low desert, where damage starts around the mid teens, and check city pollen rules first.	One of the great Tuscan oil olives, with a balanced fruity, bitter and peppery flavor, on a vigorous upright tree that ripens late, around November. It crops well in the low desert and is self-fruitful, though heavier with Pendolino or Leccino nearby. Check city pollen rules first.	The classic table olive, large and good cured green or black, though like any olive it is bitter until cured. It ripens earliest of the group, giving time to cure before the holidays. A low desert tree with only moderate cold hardiness, so check city pollen rules first.	The all-round home garden olive, good for curing or for oil, and hardier in the cold than most. It grows into a big, handsome evergreen that works as an edible landscape tree, but damage still comes in the teens, so it stays a low desert tree. Check city pollen rules first.	In Tuscany this is the olive planted to pollinate others, with small fruit and a mild oil, but it also makes a dense, weeping landscape tree with good cold hardiness. It cannot set fruit on its own, so it needs a partner such as Frantoio. Low desert tree; check city pollen rules first.
