Phlox divaricata (Woodland Phlox or Wild Sweet William)
Michael's Opinion
A native Ontario woodland plant that is a show stopper in spring when drifts of colour may be found in our woods and wayside areas. Not often seen growing in cultivation but worthy of the 'award of garden merit' bestowed upon it by the Royal Horticultural Society.
