Washingtonia robusta (Multi-trunk)

Washingtonia robusta (Multi-trunk): Characteristics and Care

The Washingtonia robusta (multi-trunk), popularly known as the multi-trunk Mexican fan palm, is a multi-trunk presentation of Washingtonia robusta, formed by several specimens grouped from the base, which provides a greater volume and density effect than a single-trunk specimen.

Its clumped and lush habit makes it a very decorative option as a focal point in gardens and tropical compositions.

It tolerates moderate drought well once established and adapts to different soil types, provided it has good drainage.

At Ornacom we cultivate each specimen directly, guaranteeing a balanced size and vigorous development from the first years of planting.
