Description
Aster laevis, also known as Smooth Aster, is of great ornamental value. This giant perennial plant offers abundant and prolonged flowering in autumn, carrying a cloud of slightly frosted blue-mauve stars high above its grey-green foliage. Thia aster requires full sun to thrive and adapts to all soils that are not too heavy, even occasionally dry. It is a wild plant with subtle charm, magnificent in the background of a flower bed.
Aster laevis belongs to the Asteraceae family. It is native to North America, specifically Florida. This perennial grows with an upright and bushy habit from spring onwards. It will reach a minimum height of 150 cm (60in) when in flower and will spread over 70 cm (28in), with very rapid growth. The airy and generous flowering, loved by bees and butterflies, lasts from August to October. The light blue-mauve flower heads measure 4 cm (2in) in diameter, with a bright yellow centre. The stems are strong and branching, glaucous. The leaves are dark green with bluish reflections and a wine-red line down the middle. The basal leaves are lanceolate and toothed, while the stem leaves are clasping. This plant spreads rapidly via rhizomes.
It is impossible to imagine our gardens without beds of asters. This one is particularly ornamental. It goes well with intense magenta-red Salvia microphylla, Helianthus 'Lemon Queen', and tall rudbeckias, for example. The genus aster is extremely diverse, offering a wide range of colours and sizes. Depending on the cultivars, it is possible to extend the flowering period right through from spring to the end of autumn, allowing gardening enthusiasts to enjoy these lovely daisy-like flowers, with their rustic flair, for a large part of the year.

Planting and care
Plant Aster laevis in autumn or spring in soil that is neither very acidic nor very alkaline, light, well-worked, sandy or loamy, moist to occasionally dry, not too poor. A heavy, damp soil will shorten its lifespan. It appreciates full sun. It may be necessary to stake the plant depending on its growth (rich soil will result in a lush but less sturdy plant). Avoid strong winds that would flatten the clumps. Once established, avoid moving it as it doesn't tolerate change well. In a flowerbed, maintain a spacing of at least 80 cm (32in) around the plants. Divide the clumps every three or four years to ensure they keep flowering well. This aster may be susceptible to powdery mildew if planted in soil that is too dry and too poor.

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.
