The Highlander™ delphiniums, bred in Scotland, are tough and hardy, and very well suited to the British climate. Able to grow well in full sun or part shade, Delphinium elatum ‘Highlander Rainbow Sensation®’ will be best in a sunny spot, but make sure the soil does not dry out in summer. Oh, and did we say, its flowers are excellent for cutting, too, lasting well in a vase indoors!
