Purple Kingsley Delphinium (Delphinium x hybrid ‘Delgenius™ Kingsley’) enchants the garden with semi-double purple blooms framed by electric-blue edges, producing a dramatic, two-toned effect. These sturdy, upright stems rise over a lush mound of green foliage from late spring into summer, reaching about 20 to 24 inches in height. Breeder Bart Noordhuis has refined this Delphinium with superior disease resistance, outstanding cold hardiness, and multiple branching spikes that provide both beauty and structure. The fragrant, bee-type flowers draw hummingbirds and butterflies, adding movement and color to your outdoor space. Deer typically avoid it, making Purple Kingsley a reliable and eye-catching choice for cutting gardens, borders, or containers.

Beyond its unforgettable floral display, Purple Kingsley Delphinium boasts a compact habit and thrives in full sun with average, well-drained soil. Originating from a line of heat-tolerant hybrids, it reliably performs in warmer climates while tolerating cold winters down to USDA Zone 3. Plant it where it can shine in mass groupings, as a standalone focal point in the border, or in mixed containers. Its easy-care nature, stable stems, and ability to rebloom with proper deadheading make it an excellent option for both new and seasoned gardeners.

Purple Kingsley Delphinium Care

Place Purple Kingsley Delphinium in an area receiving at least six hours of direct sunlight daily. Provide moderately fertile, well-drained soil, adding compost if necessary to improve drainage and nutrients. Water regularly during the initial planting period to support root establishment, then maintain even moisture without letting the soil become waterlogged. A balanced, slow-release fertilizer in early spring can promote healthy growth and abundant blooms. Removing spent flowers encourages new buds, possibly extending the blooming season.

After the main flush of flowering, lightly trim spent stalks near the base of the plant to encourage side shoots and a possible second bloom. In regions with severe winters, mulching at the base offers added root protection. Container-grown specimens benefit from periodic repotting into fresh soil to maintain vigor. If blossoms are sparse, reevaluate sun exposure, watering habits, and soil condition.

Purple Kingsley Delphinium Spacing

Space plants about 16 to 20 inches apart when creating a mass planting, ensuring good airflow to minimize disease risk. For mixed borders or smaller groupings, maintain the same spacing for a visually cohesive display. If planting in a container, choose one at least 10 to 12 inches across to accommodate the plant’s root system and allow for proper growth and stability.
