Dapper® Blue is a compact Buddleia davidii selection bred for improved landscape performance, heavy flowering, and a tidy, mounded habit. Long panicles of true sky-blue flowers bloom continuously from early summer into fall, attracting a wide range of pollinators. Its medium size, strong branching, and container adaptability make it ideal for retail programs, residential landscapes, pollinator-focused installations, and mixed perennial borders. The cultivar has undergone sterility testing and was found to be approximately 99% sterile, offering enhanced environmental responsibility compared to traditional butterfly bush selections.
