Plant Family: Nymphaeaceae

Identification Hints: Also known as the yellow pond lily, this plant has large, heart-shaped floating leaves and yellow flowers that bloom in the spring or summer.

Did you Know? Spadderdock is an aquatic plant that is often found along lake edges and in ponds throughout the Eastern US. The leaves float on the surface of the water and are attached to the substrate by long thick stems. Some leaves grow below the surface near the very bottom of the stem. The yellow flowers generally appear above the water and are generally on differentstems than the leaves. The flowers eventually turn into oval-shaped fruits thatsplit open when ripe to release the seeds.

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!
