Phlox divaricata 'Sweet Lilac': foliage

Phlox divaricata, known in English as "woodland phlox", "wild blue phlox", "wild sweet William", or "Louisiana blue phlox", and in French as phlox bleu, is a woodland perennial native to eastern North America. The wild type has five-petalled mauve flowers; cultivars are available in white, blue, and pink as well.

I'm hoping this cultivar, 'Sweet Lilac', will be similar to the wild type. My landlords' got it at Valumart on the Danforth.
