First, we fell in love with the foliage. The new foliar growth is a delicious shade of caramel pink, gradually becoming lime green as the summer progresses. As the July heat intensifies, 4-6″ panicles of white pearly buds burst into creamy Astilbe like plumes. Sorbaria sorbifolia ‘Sem’ is a compact growing False Spirea, growing only to 48″, unlike the species which can reach 8′ or more. ‘Sem’ will give you moderate height without obscuring your view. Yes this form will sucker and form a thicket…but that is why you should use this shrub as a low hedge, or for filling a space that you don’t want to fuss over.
Here are the other pertinent facts: Sorbaria ‘Sem’ grows in full sun or part shade, is deer resistant and is hardy to minus 35 degrees F. Pretty and tough, don’t you think?
