Chief Joseph lodgepole pine---turns yellow with cold temperatures. How interesting! Here's what I found at the Missouri Botanical Garden website:
'Chief Joseph' is a slow-growing dwarf cultivar with distinctive yellow winter color. In the spring and summer the needles are a bright yellowish-green color, but change to golden yellow as temperatures drop and fall turns to winter. This is a truly dwarf conifer, only growing 4-6" per year. It has a generally upright habit, but can take on a slightly crooked form with age. This specimen was discovered by nursery grower Doug Will, who found it growing in the Wallowa Mountains of eastern Oregon. It is named for the famed Chief Joseph, who led the Wallowa band of the Nez Perce tribe during a tumultuous period of forced relocation by the United States federal government in the latter half of the 1800s.
