Abstract Some plant species produce an extraordinary diversity of specialized metabolites. The diverse class terpenes is characteristic for many aromatic plants, and can occur as both emitted volatiles stored compounds. Little known about how intraspecific chemodiversity phenotypic integration volatile differ intra‐individually across development between different parts, studies considering spatial temporal scales are scarce. To comprehensively investigate this diversity, we used the Tanacetum vulgare that differs in foliar terpene composition, forming chemotypes. We collected young old leaves during rosette, elongated stem, flowering stage well flower heads at stage. Moreover, stage, were extracted from including roots. Terpene profiles measured with (TD)‐GC‐MS. composition depended on specific combination chemotype, part, time point; was mainly affected by indicating stages individuals require a higher chemodiversity, potentially to mediate interactions. For terpenes, intra‐individual differences, mostly aboveground belowground found only components such richness evenness, but not functional Hill diversity. Phenotypic differed part chemotype terpenes. Our results suggest their highly plastic trait may be shaped dependence interactions environment, value each contributes fitness individual. Such variation scales, spatially temporally, should considered chemical ecological studies.
