In the garden

Phlox paniculata 'Norah Leigh' is a tall perennial in the Polemoniaceae, native to the eastern and central United States. Plants reach roughly 1.2 m and carry their bloom through the summer months, with flowers produced from June to September. The upright habit makes it a clear vertical element in a herbaceous bed. Plant into a freely draining but moisture-retentive soil; this cultivar accepts sandy, loamy or clay types provided they are kept moist but well-drained. Give a site in full sun for best performance and to encourage a sustained display; exposure on a south- or west-facing border will maximise flowering. Phlox paniculata 'Norah Leigh' is classed H7, fully hardy in the UK, so it tolerates winter cold without winter protection in ordinary garden situations. Use it towards the back of a mixed border or in groups where its 1.2 m stems can be seen and supported by lower neighbours. Allow enough space so neighbouring shrubs do not shade the crowns during its June–September bloom, and position it where the tall stems will not be knocked by garden traffic.
