What is the lifespan of a delphinium Elatum?
Snails and slugs are attracted to this plant as well as aphids, leaf miners, mites and stem borers. Frequent feedings are necessary to support the growth and heavy blooming of this plant. Considered a short-lived perennial, its lifespan ranges from 3 to 5 years. The only thing to know is that Delphinium hate heat. If you live in a hot summer location, you need to plant in the fall or late winter and grow them like a hardy annual. In locations with cool summers they become long lived perennials. Cut back to the ground when you harvest and they will often regrow and rebloom.Delphinium seeds do best with a cold treatment, so the seeds can be directly sowed outdoors in late winter/early spring when frosts are still expected. Or, after time in the refrigerator, start the seed indoors 6 – 8 weeks prior to the end of frost season.Choose a spot in full sun with shelter from strong winds. Stake early in the growing season; delphiniums’ heavy flower spikes grow on hollow stems, which can easily break. Soil should be fertile, well-draining, and neutral to slightly alkaline (pH of 6.Frequent feedings are necessary to support the growth and heavy blooming of this plant. Considered a short-lived perennial, its lifespan ranges from 3 to 5 years. More information on Delphinium. Medium variety – Pale blue flowers, wind resistant.

Overcrowding inhibits air circulation which can lead to powdery mildew and the spread of other fungal and bacterial problems. Divide or thin new growth in early spring to alleviate this problem.Delphiniums can be high-maintenance, needing just the right conditions. They prefer cool, mild summers with low humidity.

All parts of both plants are considered toxic, though it is the sprouts which are most likely to cause digestive problems if eaten.
Are delphiniums fast growing?
From seeds Raise new plants of delphiniums such as the Pacific Hybrids and Magic Fountains Series from seed: Sow seeds in pots at 13°C (55°F) in spring. Seedlings should appear in 14 days. New plants should flower in about 18 months. Delphiniums require feeding. Top-dress existing plantings in spring with compost. Feed the plants with an all-purpose slow-release granular food, such as Osmocote, in early spring; then treat them to a drink of fish-emulsion fertilizer, like Neptune’s Harvest, several times over the summer.Harvest delphinium when the first 25% to 35% of the florets are open and place in clean water. For the health of the plant and better lateral stems, cut the stem all the way down at the base.How to Plant Delphinium. Choose a sheltered location: Delphiniums prefer a spot with full sun to partial shade and rich, well-drained soil with a pH of 6.How to plant delphiniums. You can plant a delphinium at any of time of year, but spring or autumn is best as the soil will be warm and moist. Dig a planting hole and add compost or well-rotted manure in the bottom, for a nutritious boost. Delphiniums struggle in winter wet, so add grit to heavy soils to aid drainage.Sow the seeds thinly, then lightly cover with vermiculite. Don’t forget to label them. Once the seedlings have three pairs of true leaves, prick them out each into their own individual 9cm (4in) pot with peat-free potting compost with added grit. Again, don’t forget to label them.
Are delphiniums high maintenance?
Delphiniums require considerable maintenance (staking, pruning, deadheading, disease control) in order to perform well in the garden. Plants, especially taller varieties, require protection from strong winds and rain storms by means of shelter and staking. Because they are so quick to bloom, many people treat them as annuals, buying new plants every year. They are actually a short-lived perennial and prefer short, cool summers to long, hot periods. After planting, fertilize delphiniums with an all-purpose fertilizer,” he adds.Light: Delphinium seedlings need plenty of bright, indirect sunlight. Place them in a location where they receive at least 6 hours of sunlight a day.
