While not a perennial plant trial, the arboretum does offer the opportunity to demonstrate and evaluate these plants over time. In 1997 a new perennial bed was established at the UK Arboretum. Instead of planting common perennials that perform well in this area, it was decided to use the new area as a testing ground for new or unfamiliar plants that might have perennial plant potential here. Both produced a good display. Considering that most Eupatoriums prefer a wet location, this plant tolerated the drought conditions fairly well.
Plant is fairly compact and maintains a good habit.
Produces small, bright blue flowers in early summer. Spreads, but is not invasive. Has potential as an attractive ground cover. Very attractive when in bloom. Not extremely vigorous, but does produce attractive flowers.
