Sem Ash Leaf Spirea, Sorbaria sorbifolia 'Sem' (16,336), has pinkish-red, fern-like spring foliage that unfurls along deep pink stems. Its foliage really shows off in the fall!

In July and August the neat, round shrub covers itself with creamy white blossoms. This dwarf variety makes a wonderful low hedge, or a great accent.

Sem is an improvement from older Sorbaria varieties. It is compact, better-branched, and denser than others; it creates a tight, bushy little mound in the garden, making a fine low hedge or accent planting as well as a shrub border.

Sem is elegant, space-saving, and beautiful! Sem forms a neat, tidy shrub in the partly shaded garden, which adds a nice texture. This shrub is easy to grow and quite adaptable, thriving in any well-drained soil.

It is especially valuable for northern climates because of its hardiness!
