An evergreen tree with silvery green, lanceolate leaves and a twisted, gnarled trunk. Can produce small olives with proper care, though fruiting indoors is uncommon.
Bright Direct Light – 250-1000 μmol·m⁻²·s⁻¹
Requires 6+ hours of direct sunlight per day.
Place within 2 ft / 60 cm of a south or southwest-facing window for maximum light.
Ensure the plant has an unobstructed view of the sky.
Consider a PAR Meter, or PAR Meter App to measure photosynthetically active radiation as PPFD (μmol·m⁻²·s⁻¹).
Consider using Grow Lights during the wintertime when the daylight hours are shorter.
Allow the soil to almost dry out before watering.
Use room temperature rainwater, distilled water, or reverse osmosis water.
To determine when to water, use a knitting needle or chopstick to test the moisture at various depths.
To ensure optimal plant health, a pot with drainage holes is essential.
Water the plant thoroughly until water runs out the drainage holes. Then, allow the excess water to drain completely before placing the pot on a saucer or in a decorative planter.
Water considerably less in the winter months when the plant isn’t actively growing.

Olea europaea ‘Arbequina’
A small tree with a weeping habit, adaptable, tolerant of frost and poor soils, and possibly self-fertile. It produces olives suitable for eating or making excellent olive oil.
Olea europaea ‘Cipressino’
An upright, vigorous tree resembling the Italian cypress. It is hardy and shows good resistance to coastal conditions but requires a pollinator for abundant olive production.
Olea europaea ‘Frantoio’
A self-fertile tree that is also a good pollinator. It has a classic small to medium size and produces a fruity aromatic oil.
Olea europaea ‘Hojiblanca’
Recognizable for its long arching branches with distinct white undersides. It is cold-tolerant and produces long oval-shaped fruit for table and oil.
Olea europaea ‘Leccino’
With an open semi-pendulous habit, it is easy to cultivate and tolerant of various conditions. It produces high-quality olives for table and oil but is self-sterile and needs a pollinator.
Olea europaea ‘Manzanilla’
A small to medium upright tree with arching fruiting branches. It is known for its quality table olives.
