Trial Garden

Phlox paniculata ‘Franz Schubert’

6 Photos


Phlox paniculata ‘Franz Shubert’ received a very low score in our trial because the cultivar essentially failed to flower. Out of five plants, only one bloomed; however, we do not start rating floral displays until at least two plants are in bloom. It is still unclear why four out of five plants failed to bloom. ‘Franz Schubert’ was also prone to spider mite infestations. Powdery mildew was frequently observed but rarely caused significant defoliation.
