Larkspur Delphinium 'Giotto'
ABOUT
The Delphinium 'Giotto' is a striking plant known for its lush, deeply-cut, green foliage that forms an appealing mound at the base. Rising above the foliage, the standout feature of this plant is its tall spikes adorned with impressive flowers, showcasing a magnificent range of blue hues. The blooms, closely packed along the spire, present a gradient of blue tones that can vary from sky blue to deep sapphire, often with a hint of purplish tint in some varieties. Each individual flower is made up of a main, larger petal known as the "standard," which stands proud and erect, while the smaller petals underneath it are called "falls," and they flare out from the standard. In the center of the flowers, you can find a contrasting little tuft of white or a different shade of blue, known as the "bee," which adds an extra layer of visual interest to the already captivating blooms. The aesthetic appeal of the Delphinium 'Giotto' makes it a favorite choice for cottage gardens and as a vertical accent in ornamental flower beds, where its stately blooms can truly stand out.

WaterLarkspur, commonly referred to as Delphinium 'Giotto', prefers consistent moisture but dislikes waterlogged roots. Water this perennial deeply once a week, providing about 1 to 1.5 gallons per plant each time, depending on the weather conditions and soil type. During hot, dry spells, you may need to water twice a week. The key is to keep the soil evenly moist, not soggy. Allow the top inch of soil to dry out slightly between waterings to prevent root rot.
LightLarkspur thrives in full sun to partial shade. The ideal spot for it is an area that receives at least 6 hours of direct sunlight a day. However, in regions with very hot summers, providing some afternoon shade can help protect the plant from intense, scalding sunlight.
TemperatureLarkspur grows best in cooler temperatures, with an ideal range between 50 and 75 degrees Fahrenheit. It can survive minimum temperatures down to about 40 degrees Fahrenheit but may be damaged by frost. During summer heat waves, larkspur benefits from protection, as temperatures consistently above 85 degrees Fahrenheit can stress the plant.
PruningLarkspur benefits from pruning to encourage bushier growth and more blooms. Pinch back the tips of young plants in spring. After the first flush of flowers fades, cut back the flower stalks by one-third to promote a second bloom. The best time for pruning is immediately after the first flowering peak is over.
CleaningAs needed
SoilLarkspur 'Giotto' requires well-draining soil rich in organic matter with a pH ranging from 6.0 to 7.5. A good mix would be equal parts of loam, leaf mold, or well-rotted compost, and a handful of coarse sand to improve drainage.
RepottingLarkspur 'Giotto' does not generally require frequent repotting as it is commonly grown as an annual or biennial. Repot young plants annually until they reach maturity if grown in containers.
Humidity & MistingLarkspur 'Giotto' prefers moderate humidity levels but is quite adaptable. It does not require high humidity environments to thrive.
Suitable locationsIndoor

Life cycleThe life of Delphinium 'Giotto', commonly known as Giotto Delphinium, begins with seed germination, which typically occurs in early spring when temperatures are consistently around 55-65°F (13-18°C). Following germination, the seedlings develop a basal rosette of leaves, and primary roots deepen to anchor the plant. In its first year, the Giotto Delphinium focuses on vegetative growth, establishing a strong root system and foliage. During the second year and onwards, the plant sends up floral spikes in late spring to midsummer, showcasing its tall, vibrant blue, purple, or white flowers that attract pollinators. After blooming, the plant sets seeds, which can be collected or allowed to self-sow, perpetuating the life cycle. As a perennial, the above-ground foliage dies back in the fall, with the plant entering a period of dormancy over winter, preserving its energy in the root system for the next growing cycle.
PropogationPropogation time
Spring-Early Summer
For the Delphinium 'Giotto', also commonly known as Larkspur, one of the most popular methods of propagation is by seed. The best time for sowing Delphinium seeds is in early spring when the soil temperature is around 65-75 degrees Fahrenheit (18-24 degrees Celsius). Seeds can be started indoors in trays with seed starting mix. They need light to germinate, so they should be sown on the surface of the soil and not covered, or covered lightly with a thin layer of vermiculite. Keep the soil moist until germination, which should occur within 2 to 3 weeks. After the seedlings have grown sufficiently and there is no risk of frost, they can be transplanted outdoors to a sunny location with well-drained soil.
