Buddleia Buzz Sky Blue Buddleia is also known as the butterfly bush. Buddleja davidii Buzz Sky Blue is a compact, long-flowering, deciduous shrub, ideal for a patio or a small garden. The narrow elliptical leaves are an attractive grey-green. From June to September, conical heads of bright mauvish-blue flowers with a tiny orange eye are borne in profusion; the flowers are extremely attractive to bees and, especially, to butterflies.
