The plants are weak, with yellow leaves or broken stems. They'll obviously recover with a bit of care, but I'm not happy with this first part of the order. I hope the rest of the order will be in much better condition.

Description
Buddleia davidii 'Adonis Blue' is a butterfly bush with intense midnight blue flowers, thanks to the density of its inflorescence. This very vigorous bush has arching branches that give it a slightly drooping habit. It grows rapidly and blooms from July to September, producing an abundance of large paniculate flowers measuring 20 to 30 cm (7.9 to 11.8 in) in length. Its flowers are melliferous (meaning they contain substances collected by pollinating insects or some birds that will be transformed into honey) and attract butterflies and ladybugs.
The foliage of the butterfly bush is deciduous. It consists of long silver-green leaves with a grey down on the underside. This colour provides a beautiful contrast with other plants in the garden. The leaves, measuring 15 to 25 cm (5.9 to 9.8 in) in length, are pointed and lanceolate. Native to China and Japan, this blue Buddleia is very hardy. It can reach a height of up to 4 m (13.1 ft). It is a plant that is resistant to pollution.
Whether planted individually or in groups, the Buddleia davidii 'Adonis Blue' will bring intensity to your garden. You can place it in borders, especially among other shrubs, or in a free hedge. You can also pair it with other buddleias for a contrasting effect or with ceanothus for a range of blue shades.

Planting and care
Buddleia 'Adonis Blue' enjoys sunny locations. Plant it in a light, fertile, cool but above all well-drained soil. Buddleia does not enjoy hot weather, but there is no need to overwater as it will bounce back when temperatures fall. This plant has no significant enemies. However, be cautious of caterpillars, weevils, bugs, and red spider mites that can invade it.

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.
