Carpenters' Hall is getting two rare Ben Franklin trees

Driving the news: The 6-foot-tall saplings are being planted outside the historic Carpenters' Hall at the Independence National Historical Park later this month.

• The tree is known for its large, cream-colored flowers with a bright yellowy-orange center and glossy, narrow leaves.

Fun facts: Don't expect to see Franklin trees while hiking in Wissahickon Valley Park: They're extinct in the wild.

• Plus: All living Franklin trees descend from seeds originally cultivated at Bartram's Garden in West Philly.

Worth noting: It's fitting the trees will grow beside Carpenters' Hall, which was the site of Franklin's Library Company and the First Continental Congress, among other firsts.

What's next: The planting ceremony is 10am on April 25.
