Four one-foot redwood saplings and three larger redwood trees went into the ground behind the Community Center in Thursday.
Members of the Piedmont Garden Club's Conservation Committee slipped on their work gloves to help with the planting, which is part of the local commemoration of the Garden Club of America's centennial.
In honor of its 100th anniversary in 2013, the national organization asked each member club to plant trees native to their area. The Piedmont club picked the redwood as it was designated in the city's master plan in the early 1980s as the civic center tree.
The redwoods planted Thursday were grown from seeds from Humbolt Redwoods State Park where the Garden Club of America purchased a grove of more than 5,000 acres to help conserve the native tree.
