Eupatorium Gateway is a tall but compact variety suitable for a city garden. In direct sunlight, the pink color will not appear as intense as it does in this photo.Joe Pye Weed is another name for Eupatorium, an impressive garden perennial that began its career as a wild flower. In many parts of the world, one can still find varieties growing in marshes and alongside highways. The claim to fame for this family of plants has been its hardiness, height and sustainability. I grow it because its lushness just knocks my socks off !

Consider planting Eupatorium for three reasons: it is majestic, it is easy care and it flowers when many perennials have finished blooming. What it lacks in color saturation, it makes up for in height, texture, and volume.

Tall Eupatorium should be planted at the very back if a flower bed. It creates a dense textural background that enhances both the garden and the other perennials that grow in front of it. Because of its height and prominence in the late summer garden, the color of its stems becomes a notable feature of the plant as well. The picture above demonstrates the important contribution of the wine-colored stems to the overall appearance of the garden.

Between the wild and the bred cultivars, one can select an appropriate plant from a collection of more than 18 varieties. Choosing one can be challenging for some. At the beginning of the growing season, most Eupatorium look alike to the untrained eye. When in bloom, the differences between the pink varieties are subtle. Even when they are observed growing side by side, it is not easy to tell them apart.

To assist gardeners in finding the right plant for the right spot, here is a list of pink Eupatorium cultivars. Some are bushier than others while some have a wider spread. For city gardens where space is precious, consider the more compact growing varieties such as Baby Joe, Little Joe, Phantom and Gateway. The height of each of the plants listed below represents the lowest height recorded. Plants may grow taller than indicated.

Eupatorium will grow in sun or part shade, in boggy or ordinary soil, in zones 3 to 7. In the path of the moving sun, it will sprawl to follow the light. Neatest growth occurs in a southern exposure or where light remains constant. Do not expect to find all of the varieties listed above at any one nursery.
