Aconogonon x fennicum has a bushy habit. It is a fast-growing, vigorous perennial that may reach almost two metres during one season. It may be used as a screen instead of ornamental shrubs at sites where woody plants would break under the snow load. In the autumn the foliage of A.x fennicum turns a beautiful red, especially on sunny sites.
In Mustila Aconogonon x fennicum grows in the Pähkinärinne (Walnut slope) on a sunny, verdant clearance as an old and thriving small stand.
