An olive tree standard, also known as an olive tree topiary or an olive tree lollipop, refers to an olive tree (Olea europaea) that has been pruned and trained into a specific shape, often resembling a lollipop or a ball on top of a straight trunk. This pruning technique creates a more formal and compact appearance for the olive tree, making it an attractive ornamental plant for gardens, patios, and outdoor spaces.

Key features of olive tree standards include:

1. Trunk and Canopy: The trunk of an olive tree standard is usually straight and tall, with all lower branches removed to create a clear stem or "standard." On top of the trunk, the canopy is pruned into a round or ball shape, resembling a lollipop.

2. Growth Habit: Olive trees have a slow to moderate growth rate, and when trained into a standard form, they remain relatively compact and tidy, making them suitable for small gardens or containers.

3. Evergreen Foliage: Olive tree leaves are narrow and grayish-green, providing an attractive evergreen canopy throughout the year.

4. Flowers and Fruits: Olive trees produce small, fragrant, creamy-white flowers in spring, which may be followed by olives in the right growing conditions. However, in some cases, fruit production may be limited or absent due to the pruning.

5. Sun and Soil Requirements: Olive tree standards prefer full sun exposure and well-draining soil. They are drought-tolerant once established and are well-suited for Mediterranean or dry climate gardens.

6. Maintenance: Olive tree standards require regular pruning to maintain their shape and size. Pruning is typically done in late winter or early spring before new growth begins.

Olive tree standards are popular choices for creating a formal and elegant look in gardens and landscapes. Their compact size and rounded canopy make them suitable for small spaces, courtyards, and urban gardens. Additionally, their Mediterranean charm and versatile nature make them a favorite among gardeners seeking low-maintenance yet visually appealing ornamental plants.
