Description

Delphinium 'Sweet Sensation' is as charming as its name suggests, lending borders a touch of romance mixed with just the right amount of stateliness. From a neat mound of deeply lobed, fresh green foliage, tall and sturdy stems rise proudly, carrying towers of frilly, double blooms. The flowers shimmer in shades of violet, touched with hints of blue-green that give them an almost iridescent quality in certain lights. This larkspur is a natural performer, combining elegance with exuberance and ensuring it never blends quietly into the background. Instead, Delphinium 'Sweet Sensation' insists on being noticed — in the most tasteful way, of course.

There’s a layered richness to Delphinium 'Sweet Sensation' (Highlander Series) that makes it a superb anchor in summer plantings. The ruffled flowers bring depth and texture, softening the vertical spires into something both dramatic and gentle. Positioned towards the middle or back of a border, Delphinium 'Sweet Sensation' partners effortlessly with roses, peonies or even ornamental grasses, offering contrast while holding its own. Cut stems look wonderfully decadent in a vase, where their blend of violet and subtle blue-green tones offers a cool, calming presence indoors. Whether you’re after architectural impact or a dose of romantic flourish, Delphinium 'Sweet Sensation' delivers a long-lasting display that truly earns its name — a sweet garden pleasure from every angle.

Useful information

    • Soak the Delphinium 'Sweet Sensation' roots in water for 3-6 hours prior to planting

    • Plant your larkspur bare roots into temporary pots with a multipurpose compost within a week of delivery 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. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).

    • 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.
