Buy Ageratina altissima 'Chocolate' white snakeroot ( syn. Eupatorium Chocolate ): A late-flowering perennial with lovely, dark foliage

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Soil: tolerates most provided there is adequate moisture
  • Rate of growth: average
  • Flowering period: July to September
  • Hardiness: fully hardy

    Long-lasting, pure white flowerheads of this white snakeroot appear from July to September above attractive bronze-chocolate foliage. A lovely clump-forming perennial, it's easy to grow and manage, and the flowers are attractive to bees and butterflies. A versatile plant for a mixed border, this eupatorium looks great with ornamental grasses and will help extend the season of interest.

Gorgeous plant


I wanted this plant as a foil for dahlias and lupins in a herbaceous border.

Excellent condition on arrival


The product looks amazing when in flower. Just waiting for the new shoots to come up




Great plant for partial shade


Needed a plant for partial shade. Planted in a spot that only gets sun in the afternoon. Grew to 1m with really attractive dark foliage which was topped with masses of white flowers which looked like a 'froth' on the top of the plant. Planted last year, and, as I am writing this review in February, not sure of hardiness yet. An usual plant which even a learner gardener like myself managed to get growing well.

I planted five of these plants last Spring and they did really well. They died back over the winter. 1. I am wondering when I will see signs of this year's growth, it's late March and nothing yet?. 2. The area they are in isn't especially damp but I can keep them well watered. It is south facing, under a silver birch, so some light shade. How damp do they need to be to thrive?


Hello, These are late flowering, so tend to start growing later than the early-flowering perennials. Therefore, I would not really expect to see any signs of growth until May or June. As for the mositure levels, they like reliably moist but not waterlogged conditions.


Hello, I planted an Ageratina altissima a few months ago and it has taken really well - doubling in size over the Summer. However, it's now falling over - the main stems don't seem to be strong enough to support its own weight. Is this normal? Should I be supporting it with canes or has it grown too quickly? I have one on the other side of my garden which has grown much more slowly and is still upright. Thanks


Hello, These plants are happiest in partial shade, however if the shade is too dense, the plant will become 'stretched' as it reaches for more sun. This rapid, soft growth could be caused by too much fertiliser, so if it is at all possible you should address these issues.. If all else fails however, you could use some discretely placed bamboo canes to prop it up.


The trick to achieving the tropical effect is good preparation and dense planting, vivid foliage, fiery flowers and striking contrasts. The jungle garden is a place for theatrical planning and planting. If you don't have room or the inclination to turn y
