description <i>Rhododendron</i><i>simsii</i> is one of the top ten famous flowers in China. Due to its historical value and high aesthetic, it is widely popular among Chinese people. Various colors are important breeding objectives in <i>Rhododendron L</i>. The understanding of the molecular mechanism of flower color formation can provide a theoretical basis for the improvement of flower color in <i>Rhododendron L</i>. To generate the <i>R.</i><i>simsii</i> transcriptome, PacBio sequencing technology has been used. A total of 833,137 full-length non-chimeric reads were obtained and 726,846 high-quality full-length transcripts were found. Moreover, 40,556 total open reading frames were obtained; of which 36,018 were complete. In gene annotation analyses, 39,411, 18,565, 16,102 and 17,450 transcriptions were allocated to GO, Nr, KEGG and COG databases, correspondingly. To identify long non-coding RNAs (lncRNAs), we utilized four computational methods associated with Protein families (Pfam), Cooperative Data Classification (CPC), Coding Assessing Potential Tool (CPAT) and Coding Non Coding Index (CNCI) databases and observed 6170, 2265, 4084 and 1240 lncRNAs, respectively. Based on the results, most genes were enriched in the flavonoid biosynthetic pathway. The eight key genes on the anthocyanin biosynthetic pathway were further selected and analyzed by qRT-PCR. The F3′H and ANS showed an upward trend in the developmental stages of <i>R. simsii</i>. The highest expression of F3′5′H and FLS in the petal color formation of <i>R. simsii</i> was observed. This research provided a huge number of full-length transcripts, which will help to proceed genetic analyses of <i>R.</i><i>simsii</i>. native, which is a semi-deciduous shrub.
