Fraxinus latifolia aka Oregon Ash

Fraxinus latifolia, also known as the Oregon ash, is a medium-sized deciduous tree native to western North America. It can reach heights of 20 m (65 ft) to 25 m (80 ft) with a trunk diameter of 40–75 cm (16–30 in) and an average life span of 100−150 years. However, it can grow considerably larger and have a life span of over 200 years, or become stunted and small in drier habitats. The bark is dark gray–brown and develops a woven pattern of deep fissures and ridges. The compound leaves are pinnate, 12–33 cm (4 3⁄4–13 in) long, with 5–9 leaflets attached in pairs to a linear stalk and an additional leaflet at the tip. The leaves are ovate, 6–12 cm (2 1⁄4–4 3⁄4 in) long and 3–4 cm (1 1⁄8–1 5⁄8 in) broad and noticeably lighter green than those of associated broadleaf species. They turn bright yellow and fall off early in autumn. Oregon ash can be identified by its stout twigs and opposite branching arrangement and opposing buds in the fall and before it begins to leaf out. As a houseplant, Oregon ash is super rare and needs regular watering to thrive. It does best in long-lasting, direct light and should be less than 1 foot from a window. Oregon ash likes soil that is well-draining and shouldn't need added fertilizers if repotted each time it doubles in size. However, it is common for the leaves and bark to show signs of disease and brown rot on otherwise healthy plants.
