This unusual Delphinium produces spires of large flat magenta-pink discs with brown eyes in June and July. This variety has been given the Award of Garden Merit by the RHS because of its tip top performance so it is a good one to include in a mixed or herbaceous border if you want to create vertical interest. For best effect plant in odd-numbered clumps or drifts. To encourage a second flush of flowers in late summer you should cut the flowered stems back as soon as they have finished.

Garden Care: For best results choose an open spot away from taller plants. Stake with bamboo canes as they start to shoot upwards in mid-spring and protect young foliage against slug and snail damage. During the growing season apply a balanced liquid fertiliser every 2-3 weeks and wearing gloves cut back the faded flower-stems to a flowering side-shoot to encourage repeat flowering. At the end of autumn cut back and compost the faded flower stems.
