Phlox divaricata ‘Blue Moon’ is a lovely compact cultivar of our native woodland phlox.  Plants have semi-evergreen leaves and form ground covering mats.  In early spring, foliage is topped by loose clusters of large showy blue and fragrant flowers. ‘Blue Moon’ is an excellent cultivar, one of the winners of Mt. Cuba woodland phlox trials!

This perennial can be used as ground covering perennial in shade gardens, woodland gardens, shade pollinators garden, low maintenance plantings, cottage gardens or on edges of perennial borders.

This plant is black walnut tolerant and drought tolerant too, it can grow fairly well in dry shade!

Good native perennial company provide Aquilegia canadensis, asarum, Carex (C. albicans, C. plantaginea, C. platyphylla, C. pennnsylnica), Heuchera americana , Stylophorum diphyllum, Trilliiums, smaller to medium sized ferns like Dryopteris marginalis or Polystichum acrostichoides. Or with non-native perennials like some Euphorbia, Hosta, Brunnera, Ompalodes, Carex, small spring bulbs…

    Woodland Phlox Blue Moon

    Posted by Walter Gundt on 8th Sep 2020

    We ordered a fair sized group of 7 different types of plants. All of the plants came to us well packaged and were shipped to us quite quickly. All of the plants arrived in good shape and they are now thriving in our garden.
