Spiraea betulifolia ‘Tor’ – ​This is a truly wonderful small mounding Birchleaf Spirea. I had read about it for years and was fortunate enough to finally collect cuttings from shrubs planted at the University of Connecticut, Storrs campus. Emerging from purple buds in late spring/early summer small flower clusters packed with white florets set among leaf axils like popcorn. The shrub remains handsome all through the growing season densely cloaked in pretty and very clean looking green to blue-green leaves which remind me of the foliage of Betula pumila. The leaves turn glowering purple, red, gold and copper in the autumn - a standout in the fall garden. This is a great little shrub for filler, in the foundation garden, as a step down to medium-sized evergreens or lining a walkway as a low hedge. Site ‘Tor’ in full to nearly full sun planted in any good draining soil.
