Gardeners' Notes:

Soft lilac flowers that turn more pink/magenta in hot weather.
This is one of the more mildew-resistant cultivars here.

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.
In the end the plants were obscured by weeds and the growing Evodia tree engulfed them with shade.

Last summer, through twenty feet of deep shade and thick, intertwining weeds, I saw that lovely pink shining through. I ran (at least what I call running), grabbed a shovel, & did some transplanting of a limp stalk with sickly blooms but healthy roots.

This summer Franz rewarded me with 6 strong, beautiful stalks topped with glorious, showy blooms which have been happily visited by Tiger, Spicebush, and Cabbage butterflies. hummingbird moths & bees.

Yesterday morning I revisited the same dark, weed choked spot and there was another surviving Franz!
He'll be transplanted today.
This wonderful plant suffered through 20 years of neglect and came up smiling.

Beautiful large flowers. Trimmed back this summer by 1/3 and it rebloomed end of Sept to my surprise. Will do again next year.

Very beautiful phlox variety, from far back it glows a pale beautiful light sky blue color. mike.

Positive pucpuggy On Apr 27, 2006, pucpuggy from Brookline, MA wrote:

A sturdy Phlox cultivar with a soft violet canopy. Overwatering can result in Mildew, but it does resist. I have a few big clumps of it (in good sun) around a dark red rose bush that I prune slightly higher, and the contrast is lovely--very romantic. Long bloomer.

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!
