BUZZ™ Sky Blue Butterfly Bush

BUZZ™ Sky Blue is the trade name associated with Buddleja davidii ‘TOBUD0615’, U.S. plant patent PP23461, granted March 12, 2013. The [patent](https://patents.justia.com/patent/PP23461) names TOBUD0615 as a Buddleja davidii cultivar, while [Monrovia](https://www.monrovia.com/buzz-sky-blue-butterfly-bush.html) confirms the code and lists USDA zones 5–9, full sun, and a compact 24–36 inch size. Flower color is described as violet-blue by Monrovia and lavender to light blue by the [Chicago Botanic Garden](https://www.chicagobotanic.org/plant-information/plant-finder/buddleja-tobud0615-butterfly-bush). ## Siting Choose a sunny position with well-drained soil. The Chicago Botanic Garden reports flowering from June through October and recommends the plant for a small garden or container; Monrovia also lists borders, beds, and containers. Published dimensions differ: Monrovia gives 24–36 inches, while other garden references list larger values; allow for local growing conditions and pruning when planning space. ## Maintenance Water deeply during the first growing season, then water when the upper soil begins to dry. Remove spent flower heads for tidiness and prune in late fall or early spring where needed.
