[Syngenta Dark Blue Black Bee](https://www.syngentaflowers.com/ams/product/flower/70048649) ## Growing conditions Plant in full sun and fertile, well-drained soil. Delphinium elatum grows best in a sheltered spot; strong wind and heavy rain can damage flower spikes. Water during dry spells, especially while establishing, while keeping drainage good.

Syngenta describes the series as suitable for first-year flowering programs and container production. ## Maintenance Support stems where the site is exposed or spikes need help. After flowering, remove spent spikes; cutting them back may encourage a later flush. Remove dead growth after it has withered.
