'Franz Schubert' is a cultivar which typically grows to 2-3' tall and wide.

Fragrant, tubular flowers are lilac with white eyes and up to 1" wide. Individual flowers are densely arranged in terminal, pyramidal clusters (panicles to 6-12" long). Long mid to late summer bloom sometimes extends into early fall. Good fresh cut flower.

This cultivar needs spot with good circulation of air, because it can suffer with some powdery mildew.


Tall phloxes flower for long period of time, but deadheading or "Chelsey chop" will prolong the blooming time even more. Regular upright clumps. As any other tall garden phlox – the best is to place it in the center of the flower bed, because the stems naturally loose their leaves, so plant some lower perennials in front of them. Great cut flower.

Best in flower beds, both private and public landscaping projects,cottage gardens, hummingbird and butterfly gardens or some naturalization.

Beautiful combinations can be reached combining with yellow, creme, white, orange yellow or pink flowers. If you go native (or nativar) style of planting, we highly suggest these perennials :

Agastache (tall blue or bluish flowering, Agastache ‘Black Adder‘ ), lower varieties of Coreopsis tripteris, Echinacea purpurea, Echinacea tennesseensis, Eupatorium, Filipendula rubra ‘Venusta‘ or wild form, Helenium, Monarda didyma, other varieties of Phlox paniculata, Rudbeckia maxima, Rudbeckia fulgida, annual R. hirta, Veronicastrum or cultivars of grass Panicum virgatum.

Good non-native perennial combinations include Astilbe chinensis (taller varieties), Astrantia major, Delphinium, Geranium, Geum x hybridum, Hemerocallis, Leucanthemum superbum, Lilium, Persicaria amplexicaulis, Sanguisorba, Scabiosa caucasica or Thalictrum.

Very charming combinations are with nativars of native shrub – Hydrangea arborescens or non-native Hydrangea paniculata or some roses at the background.
