Should you plant a fruitless olive tree or grow olives to harvest? Both can create beautiful Mediterranean-inspired gardens in Laguna Beach and throughout South Orange County. The right choice depends on where the tree will grow, whether dropped fruit would be a problem, and whether you want olives for curing or oil.

Fruitless versus fruiting olive trees: what is the difference?
| Consideration | Fruitless olives | Fruiting olives |
|---|---|---|
| Purpose | Shade, sculptural trunks, low-mess landscapes | Harvest, edible gardens, oil or curing |
| Fruit | Absent or very limited, depending on selection | Seasonal production and potentially messy drop |
| Pollen | Depends on cultivar; Swan Hill produces extremely little | Usually windborne and potentially allergenic |
| Best locations | Pool areas, courtyards, patios, driveways | Orchards, food forests, planting beds away from paving |
| Care | Full sun, excellent drainage, careful establishment watering | Same, with additional harvest and fruit-management needs |
Swan Hill Olives®: the fruitless landscape olive
Olea europaea ‘Swan Hill’ is a distinctive grafted ornamental olive known for its attractive gray-green leaves, twisting trunks, very limited fruit production and extremely low pollen output. According to Swan Hill Olives®, these trees can reach approximately 20–30 feet tall and wide with age. They are full-size landscape specimens, not dwarf olive shrubs.
The cultivar has an unusual horticultural history. UC Davis researcher Dr. Hudson Hartmann discovered the non-fruiting selection in Australia in 1961. Its plant patent was granted in 1972. Swan Hill's official history states that the Swan Hill Olives® trademark was acquired in 2020 by Devil Mountain Wholesale Nursery. The name represents a specific selection and brand, not a generic name for every fruitless olive.
Can a Swan Hill ever make fruit? Swan Hill's own FAQ explains that a few tiny, mostly pitless “shot fruit” can occasionally develop in certain growing conditions. The nursery also recommends removing suckers that appear below the graft union; fruiting rootstock shoots should not be allowed to mature. See the manufacturer's FAQ.
Other ornamental and fruitless olive selections
Little Ollie
‘Little Ollie’ is a compact, mostly fruitless form suited to hedges, screening and containers rather than large shade-tree applications. The UC Master Gardener Program notes that occasional small fruit crops are possible. For homeowners short on space, it is worth comparing with full-size Swan Hill trees.
Wilsonii
‘Wilsonii’ is another ornamental olive selection often described as fruitless. Always verify the exact cultivar, form and expectations for fruit or pollen before ordering; “fruitless olive” is not specific enough when fruit litter really matters.

Six fruiting olive varieties to know
Manzanillo Olive — classic table olive
Manzanillo is known for olives suitable for curing, with the classic broad, silvery olive-tree appearance. The fruit can stain hardscape as it ripens or falls. View Manzanillo Olive trees.
Mission Olive — California heritage
A traditional California selection valued for cured table olives and oil. Mission is a natural fit for an edible Mediterranean-style garden. View Mission Olive trees.
Arbequina Olive — Spanish oil olive
Arbequina is an oil-oriented olive with smaller fruit and graceful evergreen foliage. It suits homeowners interested in the flavor and tradition of homegrown olive oil. View Arbequina Olive trees.
Arbosana Olive — compact oil cultivar
Arbosana offers a comparatively compact growth habit and small fruit principally used for oil. View Arbosana Olive trees.
Koroneiki Olive — Greek oil olive
Koroneiki is prized for small, oil-rich olives and a fine-textured canopy. View Koroneiki Olive trees.
Frantoio Olive — Italian oil olive
Frantoio is an Italian cultivar grown for oil, offering an attractive evergreen form in Mediterranean-style landscape design. View Frantoio Olive trees.
Important: Fresh olives are extremely bitter and should be correctly cured or processed before eating. Fruit production depends on variety, pollination, weather and the quality of tree care.
Choosing the right olive for Laguna Beach
Near a pool, terrace or driveway: prioritize a verified fruitless variety, particularly when fruit litter and pollen are concerns. In a smaller courtyard: consider a compact ornamental like Little Ollie. For a food forest or backyard harvest: select a fruiting table- or oil-olive cultivar.
Coastal exposure, soil type and slope runoff vary dramatically across Laguna Beach, Dana Point and Laguna Niguel. Olives tolerate salt air and summer drought once established, but they do not appreciate waterlogged soil. Plan mature canopy width and avoid planting a full-size olive where it will eventually crowd structures or paving.
How to plant an olive tree in Southern California
- Start with sunlight and drainage. Choose full sun and a location free from standing water. Avoid wet lawn irrigation where possible.
- Dig wide, not deep. The bottom of the root ball should sit on firm native soil. Do not create a deep, amended basin that traps water.
- Plant slightly high. Keep the root flare visible. Swan Hill recommends the root ball crown sit approximately 1–2 inches above final grade to allow for settling.
- Handle the root ball carefully. Large nursery boxes often need specialized placement and professional equipment. Protect the roots and avoid disturbing the soil mass during installation.
- Backfill and water to settle. Fill around the root ball without burying the crown, then water thoroughly enough to settle air pockets without producing a saturated, muddy hole.
- Mulch thoughtfully. Apply a modest surface mulch ring, keeping material away from the trunk.
- Establish irrigation with observation. Use a soil probe or hand check to assess moisture in the root ball and nearby soil before adjusting watering intervals.
Large boxed olives—including 24-, 36-, 48- and 72-inch specimens—require careful site access, equipment planning and sometimes more extensive irrigation preparation. Ask about our professional planting service.
Olive watering, fertilizer and pruning
Watering newly planted olives
A new olive is not yet drought-tolerant. The Swan Hill establishment guide emphasizes the first 90 days, proper root-ball moisture and allowing the tree to acclimate over the following months. How often to irrigate depends on soil, season, weather, container size, and drainage. Check the root zone; do not rely on a fixed daily watering schedule.
Soil and fertilization
Olives are adaptable to many soil types, but chronically wet roots invite trouble. Where a Laguna Beach property has heavy clay or compacted fill, correcting drainage may matter more than added nutrients. Avoid heavy nitrogen applications to newly installed trees; Swan Hill's producer recommends waiting about a year before applying modest fertilizer when appropriate.
Pruning ornamental and fruiting olives
Preserve the olive's natural architecture. Remove dead, weak or crossing branches when appropriate, rather than topping the tree. Swan Hill recommends targeted shaping in late winter or late summer and annual removal of suckers below the graft. Fruiting olives may require additional light management and harvest-related pruning.
Common olive pests and diseases
Olive fruit fly affects fruiting olives; scale, twig borers, root and crown rot, and Verticillium wilt can also be concerns. The University of California Integrated Pest Management olive guide provides an excellent identification resource. Good drainage and careful irrigation should be part of every plant-health plan.
Common questions about olive trees
Are fruitless olives truly fruitless?
Some selections produce almost no fruit but can occasionally form a few small fruits. Verify the cultivar, especially for trees placed over patios, pools and paving.
Do Swan Hill olives produce pollen?
Swan Hill's producer identifies the selected cultivar as essentially non-pollinating, unlike common fruiting European olives, which can release allergenic airborne pollen.
Can olives grow in clay soil?
Sometimes, but drainage is essential. A broad raised planting area or a more suitable location can help where soils remain saturated.
Do olive trees need much water?
New transplants require consistent observation and establishment irrigation. Established olive trees are relatively drought-tolerant, although fruit production may improve with carefully managed supplemental water.
What is the difference between a 15-gallon and a 24-inch box olive?
Container size is only one factor. Canopy, trunk caliper, form and years of growth all affect specimen value. Ask for recent pictures and measurements when ordering substantial trees.
Which olive is best by a swimming pool?
For minimal dropped fruit, start with a verified fruitless selection such as Swan Hill and allow adequate space for its mature crown and roots.
Can Earth People deliver and install an olive tree?
