WaterLarkspur, which is a common name for the Delphinium King Arthur Group, requires consistent moisture but does not do well with overly wet roots. It's important to water the plants deeply and allow the soil to partially dry between waterings. Typically, this may mean watering once or twice a week, depending on weather conditions, with around one to one and a half gallons per plant each time. During peak summer heat and in areas with well-draining soil, frequency may increase. Monitor the top inch of soil; if it feels dry, it's time to water again.
LightLarkspur prefers full sun conditions with direct sunlight for at least 6 to 8 hours a day. The best spot would be an area that receives the morning sun and is protected from the harsh afternoon heat, especially in hotter climates. Avoid placing them in deep shade, as this will result in fewer blooms and can make the plant more susceptible to disease.
TemperatureLarkspur thrives in cooler climates and is best grown within a temperature range of 50°F to 65°F. It can endure minimum temperatures down to 40°F but is not heat-tolerant, struggling in conditions persistently above 75°F. Providing mulch can help maintain a cooler root environment during unexpected warm spells.
PruningPruning larkspur is necessary to promote vigorous growth and better blooms. Cut back spent flower stems just above a set of leaves; this will often encourage a second flush of blooms. Pruning should be done immediately after the first flowering peak, typically in late spring or early summer, and any dead or damaged stems should be removed to maintain plant health.
CleaningAs needed
SoilLarkspur, commonly known as Delphinium, prefers a soil mix rich in organic matter with good drainage. A blend of equal parts garden soil, compost, and perlite or sand works well. The best pH for this plant ranges from 6.0 to 7.5, slightly acidic to neutral.
RepottingLarkspurs do not typically require frequent repotting as they are perennial plants; repotting is generally done every 2-3 years or when the plant outgrows its current container.
Humidity & MistingLarkspur thrives in environments with moderate humidity levels. It is not a humidity-dependent plant, but excessive dryness can lead to problems. Aim for a humidity level around 50-60%.
Suitable locationsIndoor
Ensure full sun, well-draining soil, and cool temperatures.
Outdoor
Plant in full sun, use fertile, well-draining soil, protect from wind.

Life cycleDelphinium King Arthur Group, commonly known as Larkspur, begins its life cycle when its seeds are sown, typically in spring or late winter under protection. Germination occurs with warm temperatures and sufficient moisture, giving rise to seedlings with their first set of true leaves. As the plant grows, it develops a strong root system and foliage, forming a basal rosette of deeply lobed leaves. In its second year, the larkspur sends up a tall flowering spike in early to mid-summer, showcasing its majestic purple flowers with a prominent white or light-colored bee (central part of the flower). After pollination, typically by bees and butterflies attracted to the colorful blooms, the plant produces fruit in the form of follicles containing numerous seeds. The plant may die back after flowering if it is a short-lived perennial or biennial, or it may enter a period of dormancy in the winter before beginning the cycle again the following spring.
PropogationPropogation time
Spring-Early Summer
The Delphinium King Arthur Group, commonly known as the Larkspur, is often propagated by seed. The best time to sow seeds is in late winter to early spring. To propagate by seed, begin by preparing a seed tray with a well-draining seed starting mix. Moisten the mix and sprinkle the seeds thinly across the surface, then lightly cover them with a thin layer of soil. The ideal temperature for germination is between 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Keep the soil consistently moist but not waterlogged. Seedlings will typically emerge in 14 to 21 days and can be transplanted to individual pots when they are large enough to handle.
