After being a gardener at the botani cal gardens of Glasgow, he went to Oregon in 1823 as a collector to the Royal Horticultural Society, in 1825 pushing on to British Columbia where he discovered many new plants, trees and birds, and in 1827 reaching Hudson Bay. Two years later he was sent to California and the Fraser river. He died in the Sandwich islands on July 12, 1834. Douglas introduced into Britain many trees, shrubs and plants and gave his name to the Douglas spruce.
