Discussion
H. J. Scoggan (1978–1979, part 3) identified two forms of var. menziesii based upon petal color: forma menziesii (Hooker) Voss (pink to deep rose) and forma pseudosalicifolia B. Boivin (white). These appear to be local forms that may be stable; petal color can be variable within varieties and species in Spiraea and the stability of these forms, within the variety and species as a whole, has not been fully assessed. A. R. Kruckeberg (1967) tested two strains of var. menziesii and found that one showed adaptation to soils derived from ultramafic rocks (serpentinite, peridotite, dunite) and one did not. Although not discussed by Kruckeberg, variation of flower color within the variety may be correlated with substrate.
