Description
Eupatorium rugosum Chocolate, also known as Ageratina altissima Chocolate, is a variety of Eupatorium that is interesting for its opulent very dark foliage, as well as its late, white and light flowering, which is a valuable source of nectar for pollinators at this time of year. It is a perennial plant of beautiful stature, ornamental, requiring little maintenance, which thrives in a soft and loose garden soil that remains slightly moist.
Eupatorium rugosum Chocolate belongs to the Asteraceae family. Its wild ancestor is a perennial plant native to eastern North America, which thrives in wet to marshy places. A little slow to establish, this Eupatorium Chocolate eventually forms a beautiful clump that can reach 1.20m (4ft) in height when flowering, with a spread of 70cm (28in). Its above-ground vegetation is deciduous, emerging from the ground in spring and drying up at the end of autumn. The foliage of Ageratina 'Chocolate' takes on shades of brown-purple from June-July to September, then becomes greener during flowering. This foliage is composed of large leaves measuring 4 to 12cm (2 to 5in) long. It reaches its full size and wonderful coloration in full sun. The flowering usually starts in late September and continues into October. It takes the form of small white flowers grouped in light corymbs, measuring 4 to 6cm (2in) in diameter, carried on purple stems. It is a very hardy plant. However, the young spring shoots are sensitive to frost.
This Chocolate Eupatorium can be placed both as a specimen plant or in the back of a border. It can also be planted in flower beds and its flowers can be used for making bouquets. This tall perennial forms beautiful associations with autumn asters, golden or very light foliage for contrasting colours. It is a plant that delights butterflies.
According to tradition, Eupatorium is a magical plant that brings love and seduction. We haven't tried it. It is also the herb of Saint Cunegonde, an Empress of Germany from the 11th century, saint and healer.

Planting and care
Eupatorium rugosum Chocolate thrives in full sun as well as partial shade, but its foliage will be more colourful in the sun. Plant it in ordinary soil, even limestone, that is always slightly damp, but not clay (add compost to the planting soil). It is a water-hungry plant. Water it generously during the growing season if necessary, as it wilts quickly when it is hot and dry. Remove faded flowers to prolong its flowering. After flowering, lightly prune the stems that compromise its symmetry. Prune dry vegetation in late winter.

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.
