Soft lilac flowers that turn more pink/magenta in hot weather.

Being a musician, I had to have one of my favorite composers, Franz Schubert (phlox), in the garden. So I popped in three plants under an immature Evodia tree.

Years past quickly. During this time I developed some physical problems and the three Schubert's had less and less attention.

This particular variety is quite pretty, not too tall, makes babies (close by) and is one recommended by Chicago Botanic Garden as very hardy in our Zone (5a-4B) and is also mildew-resistant!
