"The Giant Sequoia Heritage Tree site is located in Courthouse Square between First Avenue and Main Street in downtown Hillsboro where pioneer nurseryman John R. Porter planted the trees in 1880.
The Porter family came west to Oregon, from Ohio, in 1847. John Porter developed an interest in trees and started a nursery on his farm. When word of the California Gold Strike reached Oregon, he rushed there to seek his fortune. On his way to California, he was awe struck by a Sequoia forest in the Sierra Nevada Mountains. Not finding the riches he had sought, Porter filled his saddle bags with cones and returned to his nursery in Oregon. Porter cultivated the seeds and planted the seedlings at various sites including the entrance to the Washington County Courthouse. Five trees remain of the original eight that were planted.
These trees are significant to the region by serving as a living legacy left by our pioneer ancestors and providing a link to the rural background of a rapidly growing area."The girth of the tree, measured at a height of 1.40 m, is 9.04 m (1997, Oregon Travel Information Council). Its height is around 45.72 m (1997, measurement method unknown, Oregon Travel Information Council). This tree was planted in 1880, which makes it exactly 135 years old (Tim B, Oct 1, 2011).
