Delphinium × cultorum 'Aurora Deep Purple'


Delphinium 'Aurora Deep Purple', which is part of the Aurora Series, is a perennial plant known for its striking flowers and garden appeal. This variety features luxurious, deep purple blooms that are densely packed on sturdy spikes, creating an impressive floral display. The flowers are shaped like little trumpets with a small central bee, or center, that contrasts in color, often appearing in a lighter or white shade which accents the deep purple petals beautifully. The plant itself has a basal mound of deeply lobed, mid-green foliage which is both lush and attractive, setting the stage for the flower spikes that emerge in the growing season. The leaves are arranged in a way that they create a somewhat rounded outline at the base of the plant. Each individual flower is made up of a set of five petal-like sepals that together form a colorful, elongated bell shape characteristic of the genus. The flowers have a delicate appearance, but they are actually quite sturdy and hold up well during the blooming period. They attract a variety of pollinators, including bees and butterflies, who are drawn to the blooms for their nectar and vibrant color. The overall appearance of Delphinium 'Aurora Deep Purple' is a display of vertical interest with its tall spikes of flowers that rise above the foliage, providing an eye-catching element in the garden landscape. The striking color and stately form make it a popular choice among gardeners looking to add height and drama to their plantings without reference to the specific dimensions of height or width.

    Larkspur, as a deep-rooted plant, requires regular watering to maintain consistently moist soil, particularly during dry spells. It’s recommended to provide a deep watering once a week, using approximately 1 gallon of water per plant. During hot, dry periods, you may need to increase the frequency to twice a week. Avoid overhead watering to prevent diseases; instead, water at the base of the plant. Ensure that the soil drains well as Larkspur does not tolerate waterlogged conditions.

  • sunLight

    Larkspur thrives in full sunlight, which means it requires at least 6 hours of direct sun per day. An ideal spot is one where the plant receives morning light and is slightly protected from the intense heat of the afternoon sun. Larkspur can tolerate partial shade, but too little light can lead to weaker stems and fewer blooms.

  • thermometerTemperature

    Larkspur prefers moderate temperatures and can generally tolerate a range between 40°F and 75°F. These plants are hardy in cooler climates and can survive short periods of frost. However, temperatures consistently above 75°F can lead to poor performance. The ideal growing conditions for Larkspur are in environments where daytime temperatures are around 65°F to 70°F, and nighttime temperatures do not dip below 40°F.

  • scissorsPruning

    Larkspur should be pruned to encourage strong stems, good air circulation, and to promote continuous blooming. Deadheading, or removing spent flowers, will encourage new blooms. Cut back the plant by one-third after the initial flowering to stimulate a second blooming period. The best time for intensive pruning is in late winter or early spring before new growth starts.

  • circleLife cycle

    Delphinium 'Aurora Deep Purple', known commonly as Larkspur, begins life as a seed that germinates in cool, moist soil in spring. Once sprouted, seedlings establish a root system and grow into young plants with characteristic deeply lobed leaves. The plant enters the vegetative stage, where it develops a strong stem and foliage, gathering energy for blooming. Larkspur's flowering stage occurs in early to mid-summer, showcasing tall spikes of rich, deep purple flowers which attract pollinators and can be cut for bouquets. After pollination, the plant produces fruit in the form of follicles containing seeds that mature by late summer to early fall, completing the reproductive cycle. At the end of the growing season, Larkspur is a perennial, typically dying back to the ground in winter, with the root system surviving to regenerate the plant the following spring.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Delphinium 'Aurora Deep Purple', commonly known as Larkspur, is typically propagated through seed sowing. The best time to sow Larkspur seeds is in late winter to early spring, where they can be started indoors 8 to 10 weeks before the last frost date. Seeds should be sown thinly in pots or trays of moist seed compost and then lightly covered with a fine layer of vermiculite. The ideal temperature for germination is around 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius), and the seeds usually germinate within 2 to 3 weeks. Once the seedlings have developed their first true leaves, they can be pricked out individually and grown on in cooler conditions until they are ready to be hardened off and transplanted outside after all risk of frost has passed.
