Campsis grandiflora (Thunb.) K. Schum is an ornamental species with various useful biological effects. The chloroplast genome of C. grandiflora isolated in Korea is 154,293 bp long (GC ratio: 38.1\%) and has four subregions: 84,121 bp of large single-copy (36.2\%) and 18,521 bp of small single-copy (30.0\%) regions are separated by 24,332 bp of inverted repeat (42.9\%) regions including 132 genes (87 protein-coding genes, eight rRNAs, and 37 tRNAs). One single-nucleotide polymorphism and five insertion and deletion (INDEL) regions (40-bp in total) were identified, indicating a low level of intraspecific variation in the chloroplast genome. All five INDEL regions were linked to the repetitive sequences. Seventy-two normal simple sequence repeats (SSRs) and 47 extended SSRs were identified to develop molecular markers. The phylogenetic trees of 29 representative Bignoniaceae chloroplast genomes indicate that the tribe-level phylogenic relationship is congruent with the findings of previous studies.
