PLANT DESCRIPTION: Eupatorium maculatum ‘Gateway’ is a compact sturdy perennial with unbranched wine colored stems.

From mid-summer until autumn, plants bear terminal dome shaped flower corymbs that are 1’ or more across. The flower clusters consist of many small feathery lavender-pink disk florets.
The blossoms mature into soft buff colored seed clusters that are attractive into the winter.
Plants are 4-6’ tall with a 2-3’ spread. Over the years, plants expand to form beefy clumps.
CULTURAL & MAINTENANCE NEEDS: Eupatorium fistulosum ‘Gateway’ prefers full to part sun. Plants thrive in fertile moist to wet soils. In drought conditions, leaves are likely to scorch.
If plants are trimmed in spring, plants will develop a bushier habit.
This species is pest resistant and foliage is unpalatable to deer and other herbivores.

COMPANION & UNDERSTUDY PLANTS: Try pairing Eupatorium maculatum ‘Gateway’ with Aster oblongifolius ‘Raydon’s Favorite’, Coreopsis tripteris, Echinacea purpurea ‘Ruby Star’, Lobelia siphilitica, Monarda fistulosa, Rudbeckia fulgida var. fulgida, Silphium perfoliatum, Solidago odora or Sorghastrum nutans.
Eupatorium purpureum and Eupatorium maculatum are worthy substitutes as they are tall plants with similar flowerheads, whorled leaves and comparable cultural requirements.
TRIVIA: Unlike other members of the Aster Family, Eupatorium spp. flowers are composed only of disc florets with no rays.
Flowers attract butterflies, skippers, moths and bees. This is a particular favorite of butterflies and often more than one species will be encountered on a flower cluster.
The Latin name of this variety has been changed to Eutrochium maculatum ‘Gateway’. Generally the former Eupatorium spp. with whorled leave are now Eutrochium spp. and the bonesets which have opposite leaves are still classified as Eupatorium spp.
