Tor Birchleaf Spirea

Spiraea betulifolia ‘Tor’

Tor® Birchleaf Spirea is a compact, cold-hardy shrub prized for its clean white spring flowers, neat rounded habit, and excellent fall colour. In late spring to early summer, it produces abundant flat-topped clusters of white blooms that contrast beautifully with its bright green, birch-like foliage.

Exceptionally tough and adaptable, Tor Spirea thrives in prairie conditions and requires very little maintenance. In fall, the foliage turns attractive shades of yellow, orange, and red, adding multi-season interest to the landscape.
