WaterLarkspur requires consistent moisture to thrive, so it is crucial to water it deeply and regularly. Aim to water the plant once a week, supplying approximately one to two inches of water, which translates to about 0.5 to 1 gallons per plant, depending on soil conditions and climate. During hot, dry spells, you may need to water twice a week. Always check the top inch of soil before watering; if it feels dry to the touch, it's time to water. Avoid overhead watering to reduce the risk of disease, and instead, use a soaker hose or drip irrigation to deliver water directly to the base of the plant.
LightLarkspur thrives best in full sun conditions, which means it requires at least six hours of direct sunlight each day. Plant it in a location where it can receive ample sunlight without obstruction. However, in regions with very hot summers, it will appreciate some light afternoon shade to protect it from the intense heat. Ensure that larkspur is planted in a spot that maximizes its exposure to sunlight throughout the day for optimal growth and flowering.
TemperatureLarkspur prefers cool to moderate temperatures and grows best when daytime temperatures are between 65 and 75 degrees Fahrenheit. It can tolerate a minimum temperature of 40 degrees Fahrenheit and a maximum temperature of around 85 degrees Fahrenheit. Avoid planting in locations where temperatures regularly exceed this range, as extreme heat can stress the plant and impede its growth.
PruningPrune larkspur after the first flush of flowers has faded to encourage a second bloom. Cut back the flower stalks by one-third to one-half to maintain a bushy and compact form. Deadheading, or removing spent flowers, will also promote continuous flowering. Prune larkspur in the late winter or early spring to remove dead or damaged tissue and to shape the plant for the upcoming season.
CleaningAs needed
SoilLarkspurs require well-draining, fertile soil with a pH of 6.5 to 7.5. An ideal soil mix can be composed of equal parts loam, organic compost, and coarse sand or perlite to ensure proper drainage and nutrient availability. Regularly enrich the soil with organic matter to maintain fertility.
RepottingLarkspurs, being perennial, do not often require repotting. They are typically sown directly into the garden or repotted only if they outgrow their current container, which may be every 2 to 3 years, or when the soil is exhausted and needs replenishment.
Humidity & MistingLarkspurs prefer moderate humidity levels, typically between 40-60%. They can tolerate some variation, but it’s crucial to ensure that the air is not too dry, as this can lead to stress and increased susceptibility to pests.
Suitable locationsIndoor
Ensure full sun, cool air, and well-draining, fertile soil.
Outdoor
Plant in full sun, provide rich soil, and ensure good air circulation.

Life cycleThe Delphinium 'Olive Poppleton', commonly known as Larkspur, begins its life as a seed which germinates in early spring when the soil is moist and temperatures are cool. The seedling emerges and forms a rosette of basal leaves as it establishes a root system. In its first year, it may produce only vegetative growth. In the following year, the plant sends up a tall flowering stalk from the center of the leaf rosette during late spring to early summer. Vibrant flowers, typically in shades of blue, purple, or white, bloom along the stalk and are pollinated by bees and butterflies. After flowering, seeds develop and are dispersed as the plant completes its life cycle, and if environmental conditions permit, the plant may survive winter and re-emerge in the subsequent season.
PropogationPropogation time
Spring-Early Summer
The Delphinium 'Olive Poppleton', typically propagated in late winter to early spring, is often done by taking basal cuttings. This popular method starts by identifying new growth at the base of an existing plant and carefully cutting a piece 3 to 4 inches (about 7.6 to 10.2 cm) long, with a clean, sharp knife. The cut should include at least a couple of new leaves and a portion of the crown. The cutting is then dipped in rooting hormone powder to encourage root development and planted in a pot filled with a mix of equal parts peat and perlite or a seed starting mix. The pot is placed in a warm area with indirect light and kept moist until roots have formed, which usually takes about 3 to 4 weeks. Once the cuttings have rooted and new growth appears, they can be transplanted to their final location in the garden.
