Eupatorium rugosum Chocolate

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.
