Young plant received in a sorry state, I hope for recovery but it seems unlikely. In general, I would say that half of my order was very damaged, with few stems and many broken ones. I was used to better quality and greater care taken with orders.

Description
Delphinium 'Guinevere Group' is an immense perennial with a very upright habit, and magnificent inflorescences that sometimes reach 1 metre (3 feet) towards the sky. They are adorned with well-distributed semi-double flower spikes, a rare, romantic lilac-pink to purple, illuminated by a small white bee in the heart of each corolla. Flowering is in June, and then again in September if the stems are cut back as they fade.
The 'Guinevere Group' Delphinium is one of the many hybrids obtained by crossing D. elatum, which gave birth, among others, to the famous "Pacific Giant" series. It is a large herbaceous perennial plant with a short lifespan but rapid growth. It forms a clump of palmate, very finely cut, tender green leaves, from which floral spikes 1 m (3ft) to 1.20 m (4ft) tall, carried by numerous stems exceeding 1.80 m (6ft) in height emerge in summer and must be staked. The wide flowers are semi-double, cup-shaped, gathered on tall erect spikes and loved by pollinating insects. They have lavender-pink, pale mauve or faded pink petals, around a tiny white collar, called a 'bee'. The plant develops from a woody rootstock that penetrates vertically into the soil.
The characteristic silhouette of Delphinium always adds breadth, height, and charm to perennial beds. They are good companions for moss or Gallic roses, creating charming and romantic scenes. You can also create a beautiful combination with pink daylilies, mauve or blue paniculate phlox, and baby's breath Rosenschleier. This variety should be carefully staked or supported by tall perennials or flowering bushes. Its flowers hold up well and are particularly appreciated in bouquets.
Note: From March to September, the stems of our delphiniums are pruned short to promote better branching of the crown and achieve optimal rooting. This also prevents the stems from breaking during transportation.

Planting and care
Plant them in spring after the last frosts, in a sunny position, in moist, rich, and well-drained soil. Leave a minimum of two or three shoots on young plants and five to seven on well-established delphiniums. During growth, water once or twice a week and apply liquid fertilizer every two or three weeks. Remove faded flowers by cutting the spikes at the level of the small lateral flowering shoots. Cut back the entire plant to ground level in autumn.
Tip: Dare to go tall with these giant plants that structure and balance the garden. The tallest ones will add volume and lightness against a dark background of hedges or conifers. The intermediate-sized ones will dress up tall flower beds, such as those of giant dahlias. Look after the vegetation with regular watering. Keep an eye out for slugs and snails, especially at the start of the growing season.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
