The museum and Consulate General of Japan are giving out the tree saplings to public gardens, parks, schools or other community organizations.
The centennial commemorates the anniversary of the large-scale planting of flowering cherry trees near the Tidal Basin and Lincoln Memorial in Washington, D.C.
The bare-root trees will be distributed later this spring to public gardens across Southern California, the museum and the consulate announced. The trees must be planted immediately after they are picked up.
Interested groups should email JapaneseGarden@huntington.org and specify the preference of cherry variety they want: Beni Hoshi, Pink Cloud, Okame or Campanulata.
