Calibrachoa hybrida is a popular ornamental plant with colorful flowers. We present here the complete chloroplast genome sequence of C. hybrida. With a total length of 156,099 bp, it is comprised of a large single-copy (LSC) region of 86,695 bp and a small single-copy (SSC) region of 18,694 bp separated by two inverted repeats (IRs) of 25,355 bp for each. A total of 132 genes were identified, consisting of 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis using complete chloroplast genomes clustered C. hybrida together with petunia into the subfamily Petunioideae within the family Solanaceae.

Bougainvillea glabra is an ornamental plant that is domesticated in many tropical and sub-tropical countries. The focus on its breeding programmes has overshadowed genetic studies of this important species. In this study, we reported on the complete chloroplast (cp) genome of B. glabra. The cp genome is 154,763 bp in size, comprised of a large single copy (LSC) region of 85,921 bp, a small single copy (SSC) region of 18,018 bp, and a pair of inverted repeat (IR) regions of 25,412 bp each. A total of 131 genes were predicted, including 37 tRNA, 8 rRNA, and 86 protein-coding genes. Phylogenetic analysis revealed that B. glabra is placed under Nyctaginaceae and sister to B. spectabilis under a strong bootstrap support.

Petunia exserta is an ornamental species on the brink of extinction in the wild. We report here the complete chloroplast genome of P. exserta, which is 156,598 bp in size consisting of a large single-copy region (87,095 bp), a small single-copy region (18,643 bp), and a pair of inverted repeats (25,430 bp for each). The chloroplast (used ‘cp’ hereafter) genome contains 132 genes, including 8 rRNA genes, 37 tRNA genes, and 87 protein-coding genes. Phylogenetic analysis demonstrated that P. exserta was most closely related to P. hybrida, and they together were closer to Calibrachoa hybrida than other taxa in the Solanaceae family.
