Here's a plant with a name that's strange. The Yellow Delphinium Eden Project range.

Delphinium semibarbatum, also known as the Yellow Delphinium Eden Project Range, is a tall plant that blooms with a mass of wonderful, pale yellow plants throughout the summer. It looks great in flower beds and borders. It’s also used in flower arrangements. It enjoys a full sun location in the garden, and is hardy enough to cope with all that the British weather can throw at it. Be aware that this plant is toxic, so take care not to plant in an area where children play.
