Delphinium has stunning bright blue flowers and is native to high mountains of tropical Africa. The main flowering stem is erect and is topped by many flowers. The flower has five petals which grow together together to form a hollow flower with a spur at the end, which gives the plant its name. The plants flower from late spring to late summer, and are pollinated by butterflies and bumble bees. The scientific name describes the shape of the bud, which is thought to look like a (rather fat) dolphin. Ordering seeds info
