sorbaria / False Spirea
This unique shrub is in a class all it's own, literally. A great plant for naturalizing the Sorbaria are subject to runners, although not as vigorous in heavier clayey soils. This can be restricted by planting this shrub inside a larger container to help restrict it from spreading.
'Sem' Ash Leaf Spirea
Sorbaria sorbifolia 'Sem'
A breakthrough in color and habit, 'Sem' is an improvement over other Sorbaria varieties in every way. Pinkish-red, fern-like spring foliage unfurls along deep pink stems. In full sun the foliage takes on a chartreuse tint and in autumn bronze hues appear. In July and August the neat, round shrub covers itself with creamy white blossoms. This dwarf variety makes a wonderful low hedge, a great accent and is pretty enough to put in a pot on the patio.
