Lubera stops plant deliveries to the UK
Due to Brexit, we are not able to deliver to the UK. We are working on a solution on how we can continue to bring a wide range of Lubera plants to the UK and directly to our customers' homes in the future. However, such a solution will not be available before 2022 or 2023.

Use

 

With their early to midsummer flowers, delphiniums are the perfect rose companions, especially as they extend the colour spectrum of the rose plants with their typical blue and violet shades. Thanks to intensive breeding work, even white and pink varieties are now available. In perennial beds, they are best shown off individually, in pairs or in groups of three, where they set the tone as leader plants. If compact growing Belladonna varieties and high Elatum hybrids are combined, the result is a magnificent picture. On the terrace and balcony, the small and medium-high representatives in plant pots of all kinds are a wonderful eye-catcher.

As the flowers of these plants are very cut-resistant and retain their colour even when dried, they also look wonderful in a vase or as part of floral decorations.

 

Different varieties in the Lubera Shop

 

Below are some popular varieties from our range:

  • Among the Elatum hybrids, the mildew-resistant 'Augenweide' has a two-tone flower in light blue (with a hint of pink) and a bright eye.
  • ‘Pagan Purples' is an Elatum F1 hybrid with long, showy blossoms and dense, double, dark blue-violet flowers on strong stems.
  • ‘Piccolo' is a Belladonna hybrid that enchants with radiant, blue flowers. It has a compact habit and grows to a maximum height of 100 centimetres.
  • The small larkspur 'Blauer Zwerg' has beautiful, gentian blue flower panicles, which are very effective in rock gardens or in the front of beds. It is relatively short-lived but likes to re-seed itself.

 

Suitable planting partners

 

Beautiful companions for delphinium are daisies, bellflowers, steppe sage, and daylilies. A stunning display is also created with medium-high ornamental grasses. Peonies provide good shade at the 'feet', which larkspurs appreciate very much.

 

Interesting facts

 

Delphiniums belong to the buttercup family (Ranunculaceae). There are about 300 species worldwide. The species and varieties adorn themselves with the typical hand-shaped, deeply incised leaves. The foliage varies, depending on the variety, between fresh green and deep dark green. Their high flower panicles appear on strong stems from June to late summer. On the back of the individual flowers, often decorated with a contrasting eye (also called a 'bee'), there is a long extension - a spur that has given the plants their name.

 

Note: if you buy this plant, you must know that all species and varieties are highly poisonous!

 

In terms of breeding, there are three groups of these hybrids, from which many attractive, hardy varieties for the garden have emerged:

  • Elatum group (Tall)
  • Belladonna group (Half or Branched)
  • Pacific group (Pacific hybrids)

The Elatum hybrids reach impressive growth heights of up to two metres and remain stable. Their inflorescences consist of large, individual flowers up to five centimetres in diameter. Since the varieties grow unbranched, they are also ideally suited as cut flowers. The well-known perennial breeder Karl Foerster was instrumental in the development of many garden forms. The representatives of the Elatum group are relatively long-lived.

 

Elatum-F1 hybrids come from New Zealand breeding. They have good winter hardiness and also prove to be very stable. They also thrive well in warm climates.

 

Belladonna hybrids, also called 'Branched Delphiniums', have a dainty growth and loose inflorescences. They appear bushy and compact.

 

The Pacific hybrids originated in the United states and develop particularly large flowers (up to almost 8 centimetres in diameter), which can also be double. They are particularly robust in heat and drought and have a medium to high growth rate.

 

Location and soil

 

A delphinium loves the sun, but likes to have shade at its 'feet'. A full sun location with low-growing companion plants is therefore very suitable for all delphinium varieties. The soil is ideally sandy-clayey, rich in humus and nutrients and the substrate should always be slightly moist. However, waterlogging is not tolerated. The soil pH value should be between 6.5 and 7. A wind-protected location is recommended, as the long blossoms can break off in strong winds.

 

Planting

 

Work some ripe compost into the soil before planting. Since these perennials are shallow-rooting, you should not plant them too deep. It is also important to ensure that there is sufficient distance from neighbouring plants to ensure good air circulation (danger of mildew!).

 

Care

 

Delphinium's nutrient requirements are high, which is why the plants should be fertilised in the spring and after pruning at the end of June. For pruning, the withered parts of the plant are cut off about 20 centimetres above the ground before the seeds are formed so that new flowers can develop by autumn. An extra dose of mineral fertiliser can also help here. Watering is absolutely necessary during dry periods.

The shoots are usually very stable - but if you want to be on the safe side, support them with a perennial ring as a precaution.

When caring for these plants, you should not forget to transplant it in the spring - it is not very durable anyway. Otherwise, the perennials will become lazy in flowering and will show less vitality overall. It is recommended to transplant them every two years in February/March, these plants like a change of location.

 

In autumn, the plants die back completely and can be cut off close to the ground.

 

Caution: the shoots of these plants are highly susceptible to snails!
