WaterLarkspur, commonly referred to as Delphinium, requires regular watering to maintain moist soil, especially during the growing season in spring and summer. It should be watered thoroughly once a week, with about 1 to 1.5 gallons of water per plant depending on the size and the weather conditions. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. During extreme heat, watering frequency may need to increase. In the fall and winter months, reduce watering as the plant goes dormant.
LightLarkspur thrives in locations with full sun exposure receiving at least 6 to 8 hours of direct sunlight per day. They perform best when placed in a spot that gets morning sunlight and some afternoon shade, particularly in regions with hot summers. Avoid heavily shaded areas as this can lead to weak growth and fewer blooms.
TemperatureLarkspur prefers moderate to cool conditions, thriving in temperatures between 55°F and 75°F. They can tolerate minimum temperatures down to about 40°F but should be protected from hard frosts. During the summer, if temperatures consistently exceed 75°F, the plants may benefit from some shade during the hottest part of the day to prevent stress.
PruningLarkspur should be pruned to remove spent flowers and encourage additional blooming, as well as to maintain plant shape and health. Deadhead the flowers once the blooms fade to promote a second flush of flowers. In late fall or early winter, after the first frost, cut back the stems to an inch or two above the ground level to prepare for winter dormancy. Pruning is typically done annually.
CleaningAs needed
SoilLarkspur 'David Mannion' thrives best in a soil mix that is well-draining, rich in organic matter, and has a neutral to slightly alkaline pH level around 6.5 to 7.5. A good mix can be composed of equal parts loam, compost, and sharp sand to facilitate drainage. Regularly enriching the soil with compost or a balanced fertilizer will support its vigorous growth and blooming.
RepottingLarkspur 'David Mannion', typically grown as an annual or biennial, does not usually require repotting because it is often grown from seed each year or replaced after two years. When grown as a perennial, repotting may be done every 2-3 years to refresh the soil and divide the roots if the plant has become crowded.
Humidity & MistingLarkspur 'David Mannion' prefers moderate humidity levels but does well in typical outdoor humidity ranges. It does not have specific humidity requirements and is adaptable to most outdoor environments.
Suitable locationsIndoor
Provide bright sunlight, keep soil moist, and ensure good air circulation.
Outdoor
Plant in full sun, fertile soil, water regularly, and deadhead.

Life cycleThe life of the Larkspur 'David Mannion' begins with seed germination, which occurs in late winter to early spring when conditions are cool and moist. As the seedlings emerge and temperatures rise, they grow into young plants with characteristic feathery foliage. During late spring to early summer, the plant develops tall flowering spikes adorned with deep blue or purple flowers. After pollination, often by bees and butterflies attracted to the vivid flowers, the plant sets seed in late summer. As temperatures cool in the fall, the Larkspur 'David Mannion' enters a period of dormancy, with above-ground growth dying back. The cycle resumes the following spring from the existing root system, or new plants can grow from fallen seeds, completing the life cycle.
PropogationPropogation time
Spring-Early summer
The Delphinium 'David Mannion', commonly referred to as larkspur, is often propagated by seed. The optimal time for sowing seeds is in the spring after the threat of frost has passed, encouraging germination in the warming soil. To propagate larkspur by seed, prepare a well-draining soil mix in a container or a seedbed, sprinkle the seeds on the surface, and lightly cover them with soil. Keeping the soil consistently moist but not waterlogged is critical for germination, which may take anywhere from 2 to 3 weeks. After seedlings have developed a couple of true leaves and are sturdy enough to handle, they should be thinned or transplanted to allow adequate space for mature growth. Larkspur prefers a sunny location with rich, well-draining soil to thrive once established.
