Looking for an impressive evergreen conifer native to the mountains of southern California? Look no further than the Pseudotsuga macrocarpa, also known as the bigcone spruce or bigcone Douglas-fir. This remarkable tree boasts the largest cones in the Pseudotsuga genus and prefers to grow on slopes and in shade. It grows up to 30 meters in height and has a straight growth form with a conical crown. The bark is deeply ridged, and the leaves are needle-like and shed at about five years of age. The female cones are exceptionally large and heavy, measuring 11–17 cm long. The bigcone Douglas-fir provides habitat for various animals and is used for watershed and habitat restoration. The wood was once used locally for fuel and lumber. Consider planting this impressive tree or supporting its restoration efforts for the benefit of California's unique ecosystems.
