Description
The Erigeron ‘Dunkelste Aller’ is a variety of fleabane distinguished by its semi-double flower heads in mauve-purple to blue-violet shades with a golden-yellow centre. Its colour, darker than that of many garden fleabanes, remains vivid and luminous in full sun. The plant forms a compact clump, from which fairly firm stems rise that generally need no staking. Very hardy and floriferous, it fits easily into sunny borders and also provides good cut flowers.
This variety belongs to the Asteraceae family. It is a herbaceous perennial: its rootstock lies dormant during winter, its leafy stems die back in autumn and re-emerge from the ground in spring. Old catalogues classified it among the Erigeron hybridus; its ancestry is probably linked to Erigeron speciosus, a fleabane of meadows and clearings in western North America. 'Dunkelste Aller' was introduced in 1951 by the German firm Benary. Its name means "the darkest of all", referring to the particularly deep colour of its flowers. The rootstock produces a basal clump of lanceolate leaves, medium green to greyish-green, long and slightly hairy. Smaller leaves adorn the flowering stems. These branch in their upper part and reach 45 to 60 cm in height, with a spread of 35 to 45 cm. They bear several flower heads 3 to 4 cm in diameter. Each has a central disc composed of small yellow flowers surrounded by several rows of very narrow, petal-like ray florets. Their colour ranges from purple-violet to blue-violet depending on the light. The main flowering occurs in June and July. By cutting back the faded stems above the foliage, new growth and a lighter second flush of flowers are obtained in late summer. The flowers attract bees, hoverflies and butterflies. This fleabane withstands harsh winters and sea air. It also tolerates a short dry period once established.
Easy to grow in rich, well-drained soils, Erigeron 'Dunkelste Aller' is highly decorative in borders and edging. It pairs beautifully with Erigeron ‘Sommerneuschnee', the shrub roses, the catmints, the hoary skullcap and the pink coneflowers. Borne on stems that are long and rigid enough, its flowers hold well in small country-style bouquets.

Planting and care
Plant the Erigeron 'Dunkelste Aller' from February to April or from September to November, in full sun in most regions. Place it in well-loosened, well-drained soil enriched with compost, even lime-bearing soil. In clay soil, plant it on a small mound or in a raised bed so that water does not stagnate around the stump in winter. Space the young plants 35 to 40 cm apart. Planting too densely, combined with heat and lack of water, encourages the appearance of powdery mildew. Water during the first summer when the soil dries out in depth. A well-rooted plant tolerates short periods without water, but regular watering encourages flower production. After the first flowering, cut back the stems above the foliage and add a little compost. Divide clumps that have become less floriferous every three or four years, in spring.

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.
