I purchased this plant some years ago because of the name Chocolate . The leaves do have an interesting color in the spring but I don't feel the flowers are worth the space the plant takes up in the flower garden. It seems to be a long lived perennial 8+ in my garden
The flowers are very attractive to insects and bloom late when there is less in the garden to feed on.

Tidy plant with pretty brownish leaves and red stems. A good accent plant. A decoction of roots was used for snakebites. Some sources report that it can spread aggressively through rhizomes or reseeding and, but I have not found that to be a problem in the Pacific NW.

Throughout late spring and summer I consider 'Chocolate' a good mid to back garden foliage plant. It has a nice rounded habit with new leaves emerging purple brown (matching the stems) and eventually turning green. When most of the garden is shutting down in early fall the dense mass of small white flowers brings a smile on. Bees love it and so do I. It's done well in dappled shade with no special attention.

Ageratina 'Chocolate' is a pollinator magnet. It is a nectar source for Monarchs and other butterflies and is a Monarch Way Station plant.

This plant is also a nectar source for bees, and supports conservation biological control by attracting beneficial insects to the garden. Beneficial insects feed on a variety of common garden pests.
