WaterLarkspur, commonly called Delphinium, needs to be kept consistently moist but not waterlogged. Water the plant deeply once a week, providing about 1.5 gallons per watering session for a mature plant. During particularly hot or windy weather, you may need to water twice a week. Ensure the soil is well-draining to prevent root rot. In the cooler months or periods of rainfall, reduce the frequency of watering to prevent over-saturation of the soil.
LightLarkspur thrives in full sunlight with at least 6 to 8 hours of direct light daily. Plant Larkspur in a position where it will receive ample morning sunlight and some protection from harsh afternoon rays in extremely hot climates. Avoid deep shade as it can lead to weak growth and fewer blooms.
TemperatureLarkspur enjoys moderate temperatures and does best with daytime temperatures between 65°F and 75°F. The plant can survive minimum temperatures down to about 40°F but may not survive freezing conditions. Larkspur prefers cooler nights and may struggle in areas where nighttime temperatures do not drop significantly from daytime highs.
PruningLarkspur should be pruned to maintain its shape, encourage bushier growth, and promote more blooms. Cut back the flower stalks after the initial blooming period to encourage a second flush of flowers. Pruning is typically done in the late winter or early spring before new growth begins.
CleaningAs needed
SoilDelphinium, commonly known as Larkspur, thrives best in a soil mix that is rich, well-draining, with plenty of organic matter. The soil pH should be slightly alkaline, between 6.8 to 7.5. A blend of loamy garden soil, peat moss, and compost with a layer of mulch on top to retain moisture is ideal.
RepottingLarkspurs are typically not grown as potted indoor plants, so repotting is not generally applicable. In garden settings, instead of repotting, you might need to lift and divide clumps every 2 to 3 years to maintain vigor.
Humidity & MistingLarkspurs prefer moderate humidity conditions and do not require high humidity levels; ambient outdoor humidity is usually sufficient for their growth.
Suitable locationsIndoor
Place in well-lit area, ensure large pot, regular watering.
Outdoor
Plant in full sun, well-drained soil, shelter from strong winds.

Life cycleDelphinium 'Langdon's Royal Flush', commonly known as Langdon's Royal Flush, begins its life cycle as a seed, which, when sown, germinates in the presence of adequate moisture and temperature. After germination, seedlings emerge and develop into juvenile plants with distinctive foliage. As the plant matures, it forms a robust root system and sturdy stems, eventually producing signature tall spikes adorned with vibrant flowers that can range in color. Following the flowering stage, the plant enters a phase of pollination, often aided by insects, which allows for the formation of seeds within the flowers. After seed set, the parent plant may start to decline, especially if it is a perennial variety, it may go dormant during the colder months, only to regrow the next spring from the root system. Those seeds, once mature and dispersed, have the potential to spawn new plants, thereby continuing the cycle.
PropogationPropogation time
Spring to Summer
Propogation: The most popular method of propagating Delphinium 'Langdon's Royal Flush' is by taking basal cuttings in early spring. To do this, a gardener would carefully select new shoots that are about 3 inches (approximately 7.6 centimeters) long, with their own roots, from the base of the plant. These shoots are then gently teased away from the main plant and potted in a free-draining compost mix. It is crucial that the compost is kept moist but not waterlogged to facilitate root growth. The potted cuttings should be placed in a bright area but out of direct sunlight until new growth indicates that the cutting has successfully rooted, at which point it can be gradually acclimatized to more direct light and eventually transplanted into the garden.
