  • water dropWater

    The Belladonna Delphinium should be watered thoroughly whenever the top inch of soil feels dry to the touch. This typically means watering about once or twice a week, but frequency will vary depending on climate conditions, with less water needed during cool, damp weather and more during hot, dry spells. Provide water directly to the base of the plant, avoiding wetting the foliage, which can lead to disease. During the growing season, a Belladonna Delphinium may need up to 1 to 1.5 gallons of water per week, adjusted for rainfall and temperature variations.

  • sunLight

    Belladonna Delphinium prefers a location with full sun to partial shade, with at least 6 hours of direct sunlight per day for optimal growth and flowering. A spot that receives morning sun and afternoon shade tends to be ideal, especially in hotter climates where intense afternoon sun can be too harsh for the plant.

  • thermometerTemperature

    Belladonna Delphinium thrives in cooler temperatures, with an ideal range between 65 to 75 degrees Fahrenheit. The plant can survive minimum temperatures down to about 50 degrees Fahrenheit and maximum temperatures up to about 85 degrees Fahrenheit. Regularly exceeding these temperature ranges can lead to stress and poor plant performance.

  • scissorsPruning

    Prune Belladonna Delphinium to remove spent flower spikes to encourage a second flush of blooms. Additionally, pruning is needed to maintain plant health by removing dead or damaged stems. The best time to prune Delphiniums is in late winter or early spring before new growth begins.

  • circleLife cycle

    Delphinium (Belladonna Group) 'Cliveden Beauty', commonly known as Delphinium, begins its life as a seed, which, when sown in moist, well-drained soil and exposed to cool temperatures, will germinate. After germination, the seedling emerges and develops into a juvenile plant with characteristic foliage specific to Delphinium species. Over time, the plant enters its vegetative state, growing taller and producing more leaves and stems. Once mature, it enters the flowering stage, typically in early summer, where it produces tall spires of densely packed flowers in shades often ranging from blue to violet, or sometimes white or pink. After pollination by insects, the plant will set seed, completing its reproductive cycle. During the fall or after the first frost, the plant will die back to the ground, with the root system surviving through winter if properly mulched, so it may regrow and repeat its life cycle in the following spring.

      Spring to Summer

    • Propogation: The Delphinium, commonly known as Larkspur, particularly the 'Janny Arrow' variety from the Belladonna Group, can be propagated through the most popular method of sowing seeds. The ideal time to sow Delphinium seeds is in late winter to early spring when the temperature is consistently around 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). You would begin by preparing a seed tray with well-draining soil, lightly covering the seeds with a thin layer of soil or vermiculite. The soil should be kept moist but not waterlogged. Place the seed tray in a bright area but out of direct sunlight and expect germination in about 2 to 3 weeks. Once the seedlings emerge and reach a sufficient size, usually having a few true leaves, they can be transplanted into individual pots before finally moving them to their permanent location in the garden.
