Ulmus parvifolia

Ulmus parvifolia
Chinese, Lacebark Elm

Seen on Park Ave. downtown on my day out. The wide green that leads up to PSU, past the art museum and farmer’s market, punctuated occasionaly by statuary.
This small tree with pale yellow-green fall color was clearly an elm, but which one? I gathered information: Much fruit present- small clumps of samaras, about 1 cm. long each. Pale green and tinged a rosy pink. Different from most elms which flower in spring and fruit in early summer. Leaves about 5 cm long and serrate. Grey sooty and black crumbly fungus (?) present on the leaves, as well as tiny oval orange-ish scale.
I consulted Dirr and determined it to be Ulmus parvifolia. (Not to be confused with Siberian elm.) I learned that many new cultivars are being made of this species. It is considered very beautiful for its exfoliating bark and its graceful form. It is quite adaptable and there is much variation in leaf form and fall color. Dirr calls it a tree of the future.
I tried to figure out what cultivar it might be, its leaves are definitely narrower than the species, which are elliptic to ovate or obovate. There are so many, but perhaps Bosque, which grows to a smaller tree, 20 feet tall, pyramidal shape and yellow-orange fall color. The species grows to 40-50’or larger.

About Mulysa

I love my work as a landscape designer and artist. When I'm not planning homesteads or working in the studio, you'll find me hiking, photographing, gardening, baking, cooking vegetarian meals with friends, reading and working on sustainability issues...with my baby on my hip in Portland, Oregon.
