Plant height — Phlox paniculata

Phlox paniculata L.

The height of Phlox paniculata is a key morphological indicator, ranging from 35 to 180 cm depending on the cultivar. The trait is evaluated during the flowering phase and significantly depends on light conditions, moisture, and soil fertility.

In the reference 13 varieties crop Garden phlox, where this is mentioned in the description.

For Phlox paniculata, bush height is a varietal trait measured during the flowering period. The value of this parameter is plastic and increases under partial shading, whereas in bright sunlight, bushes often form more compact.

Most phlox cultivars have a height in the range of 60–100 cm. This indicator determines agronomic planting standards: for dwarf cultivars, an interval of 35–40 cm is required, for medium-height ones — 50–55 cm, and for tall ones — 60–70 cm between plants.

Height directly affects the use of the cultivar in landscape design and the need for agrotechnical measures. Tall forms may require protection from the wind and the installation of supports; meanwhile, the height indicator is a decisive qualitative criterion for using the crop as cut flowers.
