Oregon Ash (Fraxinus latifolia)

Oregon Ash (Fraxinus latifolia)

This tree is native to North America and belongs to the ash genus. It stands out amongst them because of its wide leaflets, which also inspired its Latin name. The Oregon ash is a medium to large tree, its shape depending on whether it has neighboring trees or if it’s out in the open.

The Oregon ash tree has compound leaves with 5 to 9 leaflets that are arranged in pairs. In the autumn, the leaves turn bright yellow and fall quite early in the season.

It Has Gorgeous Timber

One of the most appreciated things about Oregon ash is its timber. The tree does not live for long, and after about 80 years it starts decaying from the inside out. Even if the decay process is occurring, it doesn’t mean that the wood loses its density right away. The timber presents beautiful layers of different colors, without losing its qualities.

It Thrives in California

The native range of the Oregon ash spreads between southwestern British Columbia and the Sierra Nevada mountains in California. It can thrive elsewhere if planted in wet soils near waters, and it's given plenty of water and a slowly draining, rich type of soil.

The average height of the Oregon ash tree ranges between 40 and 80 feet. It grows fast in the first 80 years, then the growth rate drops until the end of its lifespan.

Not a Usual Choice for Landscaping

It’s not common to see Oregon ash trees used as urban landscaping trees or even for private gardens. It’s most likely to find them in their natural habitat. It does attract a lot of wild birds, which can be a criterion of choice for birdwatchers. It’s also a common host for butterflies like the two-tailed Swallowtail and the Western Tiger Swallowtail.
