CAUTION: INVASIVE TENDENCIES. Ulmus pumila, commonly known as Siberian elm, is not recommended to plant, due to invasive tendencies. It is a fast-growing deciduous tree native to Eastern Siberia, northern China, and Turkmenistan. This tree typically reaches heights of 50 to 70 feet with a similar spread. It thrives in a variety of conditions, preferring full sun and well-drained soils but is adaptable to both dry and moist environments. Ulmus pumila drops a significant number of leaves and small, winged seeds, with the heaviest shedding in the spring. It is considered moderately messy due to the seed litter and leaf drop that require regular cleanup. It is a common tree of abandoned properties, salty roadsides and disturbed urban areas with compacted soils. An alternative tree to plant is Ulmus hybrids or Ulmus americana.
