  • water dropWater

    Larkspur, the common name for Delphinium 'Jenny Agutter,' prefers consistent moisture but does not like to be waterlogged. It is generally best to water deeply once a week, providing about 1 to 1.5 inches of water each time. During hot or dry periods, you may need to water twice a week, ensuring the soil is moistened to a depth of at least 6 inches. Always allow the top inch of soil to dry out between waterings to prevent root rot. Adjust the watering frequency based on rainfall, temperature, and soil conditions.

  • sunLight

    Larkspur thrives in full sun but can tolerate partial shade. For optimal growth and flower production, position your Larkspur where it will receive at least 6 to 8 hours of direct sunlight daily. If in a particularly hot climate, afternoon shade can help protect the plant from the intense heat of late day sun.

  • thermometerTemperature

    Larkspur prefers a temperate climate with temperatures ranging from 50 to 75 degrees Fahrenheit. While it can survive minimum temperatures down to about 40 degrees Fahrenheit, prolonged exposure to temperatures below this can be harmful. Ideal growing conditions include cool nights and warm days, which are characteristic of its natural growing season in spring to early summer.

  • scissorsPruning

    Pruning larkspur helps to promote vigorous growth and prevent disease by increasing air circulation. After the first flush of blooms diminishes, cut the flower stalks back by one-third to encourage a second bloom period. Deadhead spent flowers regularly to maintain a tidy appearance and improve the chance for re-blooming. The best time for cutting back plants is in late summer or early fall after blooming has finished for the season.

  • bambooSoil

    Larkspur 'Jenny Agutter' prefers a well-draining soil mix that is enriched with organic matter; a blend of loamy soil, compost or well-rotted manure, and a little sand to improve drainage works well. The ideal soil pH for larkspur should be slightly alkaline, around 7.0 to 7.5.

  • plantRepotting

    Larkspurs are generally not repotted as they are perennial plants best suited to outdoor gardens. If growing in containers, repot every 2-3 years or when the plant outgrows its current pot, ideally in the spring.

  • circleLife cycle

    Delphinium 'Jenny Agutter', commonly known as Larkspur, starts its life cycle as a seed, typically sown in spring or early summer. When conditions are right, the seed germinates, developing roots and a small shoot that will grow into a young seedling. The seedling matures into a vegetative plant, forming a rosette of basal leaves, and as temperatures become favorable, it experiences a growth spurt in which a tall flowering spike emerges. During the flowering stage, which occurs in early summer, the plant produces clusters of semi-double, soft blue flowers attracting pollinators such as bees and butterflies. After pollination, the flowers develop into follicles containing seeds that mature and are eventually dispersed, completing the reproductive cycle. During the fall or with the onset of cold weather, the plant will die back, entering a period of dormancy, unless it is grown as an annual, in which case its life cycle concludes after seed dispersal.

    • Propogation time

      Early Spring

    • Propogation: Delphinium 'Jenny Agutter', commonly known as Larkspur, is typically propagated by seed. The best time to sow Delphinium seeds is in late winter to early spring. To propagate by seeds, sprinkle them on the surface of a pre-moistened seed-starting mix and gently press them into the soil without covering them, as they need light to germinate. Maintain consistent moisture and a temperature of about 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Seedlings usually appear in 14 to 21 days. Once the seedlings have developed true leaves and are large enough to handle, they can be transplanted into individual pots and gradually acclimatized to outdoor conditions before planting them out in the garden after the risk of frost has passed.
