Chinese elm (Ulmus parvifolia)


Plant Family: Elm (Ulmaceae)
Project BudBurst Plant Group: Deciduous Trees and Shrubs

Identification Hints: The bark of Chinese elms is verydistinct. It has a mottled look with flaky gray, tan, and red bark. This feature is what has also given it the name of Lacebark elm. The leaves are small, 2-5 cm long to 1-3 cm wide, green, and toothed. The flowers are small and inconspicuous. The fruits are flat and round with a seed encapsulated in a papery, wing-like outer covering.

Did you Know? The Chinese elm, as the name suggests, is native to China and other eastern countries. It is also known as the Lacebark elm. This tree can grow to between 30 and 60 feet tall. The Chinese elm is oftenfound in harsh landscape environments such as parking lots and along streets. An interesting fact is that it is also popular as a bonsai plant.

The table below displays all the data that has been submitted to Project BudBurst. By default, the data is sorted by the date on which the phenophase occurred. Clicking the up and down arrows next to each column name allows you to sort on any value. If there have been more than 10 observations submitted, you can choose how many to display at a time using the "Show __ entries" control. You can also page through the data using the previous and next buttons at the bottom right of the table.

The Search box allows you to search all of the data. Searching by date, species, phenophase, etc. is easy—just start typing and the table will immediately change to contain only observations that contain your search phrase. Do you want to see only 2012 observations? Just type "2012" in the search box. Only want to see maples? Enter "Acer." You can combine searches, too! Searching for "acer 2012" will narrow your results to only the maples that were observed in 2012 (assuming that any observations exist, of course).

Once you have your results in the order desired, you can use any of the buttons above the search box to copy the results to the clipboard; save them as a text, or spreadsheet; or even print them from your browser!
