Larkspur (Delphinium) - Characteristics and care tips

The Content Of The Article:

Art / Family: Shrub. Belongs to the family of the buttercup family (Ranunculaceae)
maintenance effort: Medium. Sensitive to non-optimal site conditions and lack of care
heyday: June to August with long flower candles consisting of dense blue, violet, yellow, red or white flowers that shimmer silky in the sunlight. Post-flowering possible in summer; for it cut back after the first pile to about 10-15cm above the ground. Then water well and fertilize
foliage: Hand-shaped deeply lobed leaves in fresh green
growth: Taut upright, bushy and compact habit with tight, straight, flower stems
Height / width: 30 to 200m high and 20 to 60cm wide
Location: Sunny protected and cool, with high brightness is also tolerated half shady. Humus and nutritious, sandy loamy soil, permeable to water. Shading of the root area makes sense, so that earth does not heat up too much, which weakens the plant (susceptibility to diseases or pest infestation increases)
planting time: Autumn. May be sown directly from February-April in the field. One must expect a germination period of 12-20 days at a temperature of 12-16 degrees Celsius
cutAfter the first Flor pruning to about 10-15cm above the ground, post-flowering promotes autumn
partner: Above all, yellow, orange or pink flowering perennials. Keeps the tall Bartiris (Iris Barbata-Elatior) aphid-free and lets it grow healthier and stronger
Can not be reconciled: Does not like his peers right next to you. Does not tolerate high-growth perennials in its neighborhood
proliferation: By division or cuttings in spring
maintenance: Support high varieties. Especially when budding in spring protection against snails needed. Compost or organic fertilizer in spring, no further fertilization required, because otherwise plant gets weak leaves and prone to pests or diseases. Water dry in case of dryness
wintering: Mostly hardy, but some species sensitive to frost
Diseases / pest:
Shady locations weaken the plant and promote disease and pest infestation
Powdery mildew: White wipeable coating - Cut off affected shoots. In case of heavy infestation, use spraying agent (observe dosage instructions). Preventively, a plant tonic can be used. Plant resistant varieties (such as 'doubles mixture')
Are very popular with snails, especially the new shoot must be urgently protected. If the feeding damage is too big, delphinium does not flower or even dies
Comes from the northern hemisphere
Is considered the most popular garden plant in Germany
It is often referred to as the Blue Gem of the garden due to its eye-catching flowers
Very popular bee feed station
Low varieties can also be cultivated in the bucket
Support high varieties as early as May
Very good and durable cut flower
Is considered a long-lived perennial that should be rejuvenated after about 10 years (see below rejuvenate Larkspur)
Some varieties will become lazy after 4-5 years, then take up and replant or split
It weakens at a non-optimal location or lack of care and is then very susceptible to disease or pest infestation
Great Blood Larkspur - Dwarf Delphinium (Delphinium grandiflorum)
Height 30-50cm. Blooms from June to August with cup-shaped gentian blue flowers. Does not tolerate low temperatures, therefore winter protection necessary. Can withstand protection in harsh areas. Comes from Western China and Siberia, where it usually grows only once a year and provides by seed shedding for offspring
Tall Delphinium (Delphinium elatum hybrid)
Height 80-200cm, 40-60cm wide. Blooms from June to July with flower candles consisting of densely fitting large flowers in purple, blue, white or pink often with a different colored eye. Upright unbranched growth. Perfect classic rose companion. Probably the most magnificent larkspur and most important hybrid group. Characterized by long and dense inflorescences
Magic Fountain varieties
Newly bred variety group with low-growing plants, which are characterized by a high stability in the wind
Low Delphinium (Delphinium Belladonna hybrid)
Height 100-120cm. Blooms from June to July with flower candles quite loosely filled with blue, purple or white flowers. Richly branched growth. The difference to the big brother (the high delphinium) is small but fine. The flowers are rather loose on the flower candles, not very dense in the high species. In addition, it has a good branching, while the high delphiniums spur no branching
Summer Larkspur - Field Larkspur - Field Larkspur (Delphinium consolida, Syn. Consolidaregalis)
Flowers in pure blue. Can be grown by seed itself better than any other species
(Delphinium Pacific hybrid)
The US-originating Delphinium Pacific hybrids are about 1.80m high, but are not particularly suitable for German gardens, as they do not appreciate our climate and very easily overturn

From a botanical point of view, the petals that we have so much to look at are transformed sepals. The fanbase of the larkspur called the flower center bee.
The German name Larkspur received the plant due to small flower appendages, which remind a little of spurs, which had the knights on their shoes at that time
Rejoice delphinium
The whole eyrie is carefully lifted out of the earth with the spade and then split with the spade blade in the middle. The spade blade should therefore be sharp. The hands are then removed in about the same size individual pieces and replanted, the new substrate should be worked up with a little fertilizer. For better growth is extensively watered so that the roots get proper ground contact.
