Wilsonii Olive Tree
Majestic Beauty olive tree
Dwarf fruitless Olive tree
Swan Hill fruitless olive tree
The Wilsonii olive tree is a highly sought-after, easy-to-grow evergreen shade tree known for its majestic beauty. As a fruitless cultivar derived from the Manzanillo olive, it is an excellent addition to a variety of landscapes.
This tree is drought-tolerant once established and resistant to fire and disease, making it a low-maintenance choice. With its striking multi-trunk form, the Wilsonii olive tree adds dramatic visual appeal. Its adaptability and hardiness allow it to live for hundreds of years. Unlike fruiting olive trees, the Wilsonii does not produce olives, eliminating unwanted mess and pollen that can trigger allergies.
