[Exact Excalibur White Bee profile](https://www.syngentaflowers.com/ams/product/flower/70001033) ## Garden Placement Use the upright spikes as a strong vertical accent in a sunny perennial border or a large container. The breeder describes Excalibur as well-branched with sturdy stems and suited to larger pots; allow enough space for its listed spread. ## Growing Conditions Plant in fertile, well-drained soil and shelter the stems from strong wind. Consistent moisture supports active growth, while good drainage helps reduce crown and root problems. ## Maintenance Check tall spikes as they develop and stake where wind or heavy rain may cause leaning. Remove spent flower stems after blooming and clear withered foliage at the end of the season. [RHS Delphinium elatum guidance](https://www.rhs.org.uk/plants/5398/delphinium-elatum/details)
