Common garden climates over data collection periods contrasting with historical climates of tree origins and their corrections with the traits. Comparisons of mean annual temperature (MAT; A) and mean annual precipitation (MAP; B) between a common garden and tree origin sites of three demes (North, South and Oregon) with P-values shown based on Wilcoxon test. We used MAT and MAP over years 2008–2010 for propagules growing in the common garden and 30 years (1961–1990 normals) for the original natural sites (data extraction detailed in Additional file 1: Note S2). (C) Radar plot showing all trait-climate correlations in the common garden settings. All traits are grouped into three categories (phenology, biomass, and ecophysiology). The position of traits along the radial axis indicates the strength of correlation. The solid black line represents zero correlation; the region inside (or outside) this line represents negative (or positive) correlations, respectively. The maximum negative and positive correlations are − 0.58 and 0.61, respectively, marked on the graph. See Table 1 for concise annotation for the traits
