Winged Elm Ulmus alata
Other Common Name(s):

- Description
-
Winged elm is a woody, deciduous tree in the elm family (Ulmaceae). It is native to eastern and central North America. Winged Elm grows 40 to 60 feet tall and 20 to 40 feet wide.
It prefers full to partial sun and moist soil with good drainage. It tolerates different soil types, including those that contain loam, clay, sand or rocky material and is not particular about soil pH. The fertility of the soil and moisture determine the ultimate size of this tree. Regularly prune young trees to eliminate multiple trunks. It is propagated by seed.
This elm is valuable to wildlife as a source of food, nesting and habitat. When grown in an open site, it has a short bole (the trunk below the crown) and branches arching upward to form a rounded crown. In a forested site, the tree tends to grow taller and straighter. The heavy wood is used for furniture, crates and boxes.
Landscape uses for winged elm include woodlands and naturalized areas, shade trees or street trees, and butterfly, native, pollinator and winter gardens. In fall, the leaves turn yellow.
Insects, Diseases, or Other Plant Problems: Insect problems include beetles, borers, caterpillars, leaf miners, and scale. Particularly susceptible to Dutch Elm disease (a fatal fungal disease spread by beetles with no effective cure), powdery mildew, phloem necrosis, cankers, and leaf spots can be problems, especially on stressed trees.

- Wildlife Value:
- This plant supports the following larvae: Painted Lady (Vanessa cardui), Eastern Comma (Polygonia comma), Mourning Cloak (Nymphalis antiopa), Question Mark Butterfly (Polygonia interrogationis). Questionmark butterflies have an interesting life cycles: overwintered adult Question Mark butterflies lay eggs from spring until the end of May. These will appear as summer adults from May-September, laying eggs that then develop into the winter adult form. The winter adults appear in late August and shelter for the winter starting the cycle all over again. Adult Question Mark butterflies feed on rotting fruit, tree sap, dung, and carrion only visiting flowers for feeding when absolutely necessary. Painted Lady (Vanessa cardui) and Red-spotted Purple (Limenitis arthemis astyanax) rarely use this host plant in North Carolina. It is also a host plant for the Red Spotted Purple butterflies. The seeds are eaten by songbirds and small mammals.
