Description

This is a rare opportunity to grow one the most unusual—and delightful—of modern delphiniums. Delphinium 'Rainbow Sensation' has flowers that are fully double and pink-lilac, but with a creamy yellow centre. When the flowers are just open, there are blue tints on the outer petals. The whole effect is of a muted rainbow—hence its name!

The flower rosettes are produced during summer, and held high, on strong stems. Well, we say high, but actually being one of the Highlander™ series of delphiniums, this is shorter than most, with stems just 80-100cm or so high, meaning that it is suitable for growing in a container, as well as the border. 

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!

Useful information

    • Soak your Delphinium 'Rainbow Sensation' roots in water for 3-6 hours prior to planting.

    • Plant your "Larkspur" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
