WaterFor the Larkspur 'Atlantis', ensure evenly moist soil without letting it become waterlogged. Water the plant deeply once a week, providing about one to two gallons per plant, depending on weather conditions. During hot and dry spells, you'll need to water more frequently, ensuring that you always check the soil moisture before adding more water. Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. It's important not to let the soil dry out completely, as consistent moisture is important for the health of the Larkspur.
LightLarkspur 'Atlantis' thrives best in full sun to partial shade. Choose a spot in the garden that receives at least 6 hours of direct sunlight each day. If you're in a particularly hot climate, provide some afternoon shade to prevent stress from excessive heat.
TemperatureLarkspur 'Atlantis' prefers a temperate climate with temperatures ranging between 50 and 75 degrees Fahrenheit. It can tolerate a minimum temperature down to about 40 degrees Fahrenheit but will struggle in hot conditions above 85 degrees Fahrenheit. For best growth, maintain a stable environment within the ideal temperature range.
PruningPrune your Larkspur 'Atlantis' to remove spent flower spikes after the initial bloom to encourage a second flowering period. Cut back the plant by about one-third in late summer to maintain a tidy appearance and promote healthy growth. Pruning is also important to prevent self-seeding if you wish to control the spread of the plant. The best time for pruning is immediately after the first flush of flowers fade.

Life cycleThe life cycle of the Belladonna delphinium 'Atlantis' begins with seed germination, which occurs in the early spring when soil temperatures warm. The seedlings emerge and grow into juvenile plants, developing a rosette of basal leaves. As the plants mature, they develop long, sturdy flower spikes with blooms in shades of blue, purple, or white during late spring to early summer. After flowering, if the flowers are not deadheaded, they will produce seeds that can be dispersed by wind or wildlife, facilitating the next generation. During late summer or fall, the plant enters a period of dormancy where growth slows and the plant conserves energy. In subsequent seasons, the Belladonna delphinium 'Atlantis' will continue its life cycle, growing from the perennial crown and producing new shoots and flowers annually.
PropogationPropogation time
Spring to Summer
Delphinium (Belladonna Group) 'Atlantis', also known commonly as Atlantis larkspur, is often propagated by seed since it does not typically come true from divisions. The best time to sow the seeds is in spring after the threat of frost has passed, or they can be started indoors around 8 to 10 weeks before the last expected frost date. Start with a seed tray filled with a well-draining seed starting mix. The tiny seeds should be sown on the surface of the soil, lightly covered with a fine layer of soil or vermiculite, and kept moist. Consistent moisture is vital for germination, which generally occurs within 2 to 3 weeks if kept at a temperature of about 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Once the seedlings have developed their first true set of leaves and are large enough to handle, they should be transplanted into individual pots to grow on before being planted out into the garden.
