Butterfly Bush
Ordered, received and planted in September 2025, the young plant has developed very well and the flowers were very quick to arrive. It is now March 2026 and it is still magnificent and growing very well, without having lost its leaves (North Finistère, on the coast). And what a scent!

Description
Buddleia 'Silver Anniversary' is a particularly bright variety of bush with grey and silver foliage adorned with white and buff panicles. Compact and bushy, it forms a large ball of light that fits perfectly in a contemporary design or a white garden. It is a truly decorative shrub, but not hardy everywhere. It is much less resistant to cold than Buddleia davidii, but it is more water-efficient and does not self-seed.
Buddleia 'Silver Anniversary', also marketed under the name 'Morning Mist', belongs to the Scrophulariaceae (Buddlejaceae) family. It is an English horticultural creation by Peter Moore. Its first parent, the African-origin Buddleia loricata, has given it its bushy habit and white flowers, but also a lower hardiness. Its other parent, Buddleia crispa, is a more hardy Himalayan species from which it inherited its beautiful almost white fluffy and crisped foliage, but with a lower tolerance to summer drought. The hardiness of this variety does not exceed -8°C (17.6°F) at its peak for an adult plant. 'Silver Anniversary' is a fairly fast-growing, well-branched, dense bush with an overall spreading habit, reaching an average size of 1.5 m (5 ft) in all directions. Its branches bear oval leaves, 8 to 10 cm (3 to 4 in) long, covered with an almost white down. They persist more or less in winter, depending on the temperatures. Flowering takes place from July to September. The vegetation is adorned with rounded panicles measuring 7 to 8 cm (3 in) in diameter, composed of numerous small tubular white flowers with a buff-orange eye. Their honey scent attracts many butterflies and other pollinating insects.
Buddleia 'Silver Anniversary' thrives in well-drained soil, in a sunny position. Plant in the ground in regions with mild winters. It can be planted as a standalone, in a hedge, or in a shrub border. In a white garden, consider pairing it with mugworts and plant silver mound at its base, for example. Its bright and soft colour will perfectly match all the colours in the garden. It will beautifully enhance the flowering of roses or orange or yellow bush cinquefoils. It can also be grown in a large container, allowing gardeners to place it on a contemporary terrace and protect it from severe winter cold.

Planting and care
Plant in spring in cooler regions, and in early autumn in warmer areas. It thrives in well-drained soil, even limestone, in full sun. Its cold resistance is limited, up to about -8°C (17.6°F) for a well-established young plant, in well-drained soil, and sheltered from cold winds. This variety tolerates summer drought fairly well once rooted. However, a few spaced and deep waterings will be necessary in summer in hot climates.

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.
