- Water

To water effectively, apply water directly to the base of the plant to keep the foliage dry and reduce the risk of disease. During the growing season, water the larkspur deeply once a week with approximately one to two gallons of water, ensuring that the soil is moist but not saturated. During periods of high heat or drought, you may need to water twice a week. Always check the top inch of soil for dryness before watering to avoid overwatering
- Light
Larkspur, the common name for Delphinium 'Langdon's Pandora', thrives in full sun to part shade. For best growth and flower production, place it in an area where it receives at least 6 hours of direct sunlight daily. If you live in a region with intense midday sun, provide some afternoon shade to prevent stress on the plant
- Temperature
Larkspur, the common name for Delphinium 'Langdon's Pandora', prefers cooler temperatures with the ideal range being between 60 and 75 Fahrenheit. It can tolerate minimum temperatures down to about 50 Fahrenheit but is sensitive to heat above 85 Fahrenheit. Avoid placing your larkspur in locations that experience extreme heat for best growth and bloom production
- Pruning
Larkspur, or Delphinium 'Langdon's Pandora', benefits from pruning to maintain its shape, encourage bushier growth, and improve air circulation. Deadhead spent flowers regularly to promote continuous blooming throughout the season. After the initial flush of flowers, you can cut back the flower stalks to the ground to encourage a second, though less vigorous, bloom period. The best time for major pruning is in late winter or early spring, before new growth begins
- Cleaning
As needed
- Soil
Larkspur requires a well-draining soil mix with a pH between 6.0 to 7.5. A good mix could consist of equal parts loam, compost, and sand or perlite to ensure good drainage and fertility.
- Repotting

- Life cycle
The Larkspur 'Langdon's Pandora' begins its life cycle with seed germination, which typically occurs in spring when the soil has warmed. The seedlings rapidly develop true leaves and a root system. As the plant matures, it enters the vegetative stage, growing tall flower spikes adorned with distinctive purple or blue flowers that bloom in early to mid-summer. After pollination, often by bees, the flowers produce small black seeds by late summer or early fall. These seeds can be dispersed by wind or fall to the ground to enter a period of dormancy until the next spring. The plant is a perennial, so after the blooming period the aerial parts may die back, but the plant will re-sprout from its root system for the next growing season.
- Propogation
Propogation time
Spring to Summer
Delphinium 'Langdon's Pandora', commonly known as Larkspur, can be most effectively propagated through seed sowing. The most popular method for propagating Larkspur involves planting the seeds directly into the ground where they are to grow. This is typically done in early spring when the soil can be worked and the risk of a hard frost has passed. The seeds should be scattered onto well-drained soil and covered lightly with about an eighth of an inch (3 mm) of soil, as they require darkness to germinate. Keeping the soil consistently moist but not waterlogged is crucial for successful germination. Germination should occur within 2 to 3 weeks if the temperatures remain around 55 to 60 degrees Fahrenheit (13 to 16 degrees Celsius). Seedlings must be thinned out to prevent overcrowding, ensuring robust growth and development of the plants.
