What really makes this plant stand out is the scent — a very sweet rose scent that's better than a rose. If you have a clump of this in a corner or near a path, walking by it will fill your senses with a wonderful fragrance. Benjamin Vogt / Monarch Gardens How to use it. Plant in the back of a border or as a massed plant. It makes a perfect backdrop for low plants, but also looks neat among short grasses. Be sure to also enjoy its fall color, as seen above.

Planting notes. Filipendula needs a consistently moist soil, from wet to medium (but not dry at any point). It will let you know if it's too dry by turning crispy brown in a hurry, so use it in a rain garden or low area where water tends to collect for a short period.

It will very slowly spread to form a colony in clay, and will spread moderately in loam, so plan accordingly. It is not overly aggressive, and easily pulls out by hand where you don't want it.
