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.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
