While not part of Q-Elementary's American Heritage Tree Collection (see separate entry), this Prunus serrulata 'Kwanzan' (also spelled 'Kanzan') is nevertheless significant for both its extraordinary beauty and its considerable size.   


Larger than any of the scores of Kwanzan cherries that line Marietta's Front Street, this grafted cultivar may be the largest of its kind in Lancaster County.  If listed, it would rank 4th largest in the entire state of Pennsylvania, according to data at  In 2019 its trunk circumference was approximately 120 inches, its height about 35 feet, and its spread about 30 feet.


Another elementary school in Lancaster County (Martin Luther King; see separate entry) also boasts a large Japanese cherry, although of a different species.   When in bloom, these two striking trees are peers in beauty.


This amazing cultivar has been bred for fuller blossoms (up to 28 petals each) than its natural species (5 petals).  Interestingly, many people in Japan would consider Kwanzan rather gaudy.
