WaterLarkspur requires regular watering to maintain moist soil, especially during its growing season in the spring and summer. Aim to water deeply once a week with approximately 1 gallon per plant, allowing the soil to dry out slightly between waterings. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. In periods of extreme heat or dryness, increase the frequency to twice a week, ensuring that the water penetrates deeply into the soil to encourage strong root growth.
LightLarkspur thrives best in full sunlight, needing at least 6 to 8 hours of direct sun per day. It prefers a spot in the garden that receives morning light and is protected from intense, late-afternoon sun, which can sometimes be too harsh. Overly shaded areas can lead to weak growth and fewer blooms, so ensure it is positioned to receive ample sunlight.
TemperatureLarkspur is best suited to temperate climates and can generally handle a temperature range from 40 to 80 degrees Fahrenheit. The ideal growing temperature for Larkspur is between 50 and 75 degrees Fahrenheit, which encourages healthy growth and flowering. These plants can be sensitive to extreme heat, so during hot spells, extra watering may be necessary to keep them cool.
PruningPruning Larkspur is important for promoting vigorous growth and a second round of blooms. Deadhead spent flowers regularly to encourage new ones. After the main bloom in late spring or early summer, cut the Larkspur back by half to maintain a compact shape and potentially stimulate a second, smaller flush of flowers in the fall. Pruning is also necessary to remove any damaged or diseased stems to maintain plant health.
CleaningAs needed

Life cycleDelphinium 'Conspicuous', also known as Larkspur, begins its life cycle as a seed, which, when sown in fertile, well-drained soil and given adequate sunlight and water, germinates and sprouts into a seedling. The seedling phase involves the growth of the first leaves and the establishment of a root system. As it matures into a vegetative plant, it develops a sturdy stem and a lush foliage of deeply cut, green leaves; this phase is crucial for gathering energy through photosynthesis. The next stage is the flowering period, where tall spikes adorned with conspicuous, vibrant blue or purple flowers emerge, which are attractive to bees and butterflies. After pollination, typically by insects, the flowers produce fruiting bodies that contain seeds, completing the reproductive cycle. Finally, as a perennial, the Larkspur may enter a period of dormancy during colder months, only to regrow from its root system once favorable conditions return.
PropogationPropogation time
Spring-Summer
The most popular method of propagating Delphinium 'Conspicuous', commonly known as larkspur, is through seed sowing. Seeds can be started indoors about 8 to 10 weeks before the last expected frost date in your area. Sow the seeds shallowly, at a depth of approximately 1/8 inch (about 3 mm), in a well-draining soil mix. Keep the soil consistently moist but not waterlogged, and maintain a temperature of about 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius) for optimal germination. Seedlings typically emerge in 2 to 3 weeks. After the risk of frost has passed and the seedlings are strong enough, they can be transplanted into the garden, making sure to space them about 12 to 18 inches (30 to 46 cm) apart to allow for proper growth and air circulation.
