The Phlox subulata 'Benita', often also called Creeping Phlox or Moss Phlox, is a beautiful hardy perennial that brings a calming, blue-violet sea of blossoms to your garden. With its dense, mat-forming carpets, which are covered in a striking floral display in spring, this plant adds a touch of nature to any environment.

The stems are robust and creep flat along the ground, giving the plant an additional dimension.

💧 Watering / Water
Unlike many other garden perennials, Creeping Phlox likes it moderately dry to fresh, tolerates heat well, and avoids too much moisture.
-
keep soil moderately moist in spring, very drought-resistant in summer
-
definitely avoid waterlogging
-
best to water only when the topsoil layer is well dried out
-
waterlogging, however, quickly leads to root rot.
🌼 Fertilizing
-
from spring until the start of flowering: a single application of mature compost or light perennial fertilizer
-
after flowering: optionally very lightly re-fertilize to support new growth
-
stop fertilizing completely in autumn and winter
-
over-fertilization can lead to leggy growth and sparse flowering.
🌱 Substrate
A loose and breathable soil climate is important for the roots:
-
low in humus to moderately rich in humus
-
very well-drained (sandy-loamy or gravelly)
-
neutral to slightly calcareous pH value
-
A mixture of normal garden soil and a generous portion of sand or fine gravel works ideally.
🪴 Repotting / Planting
-
optimal planting time is spring or early autumn
-
when planting in the garden, maintain a distance of approx. 25–30 cm (approx. 7–9 plants per square meter)
-
Unlike deep-rooted perennials, this shallow-rooted phlox loves wide open spaces or shallow planting bowls.
✂️ Pruning
The Phlox subulata 'Benita' does not require daily pruning, but it will thank you for an annual maintenance pruning:
-
cut back by about half directly after flowering
-
this keeps the cushion compact, strong, and prevents the center from thinning out
-
remove dried stems close to the ground in early spring
-
use clean and sharp tools.
🌱 Propagating Phlox 'Benita'
Propagation is quite easy by division or cuttings:
-
after flowering, carefully divide the dense root ball with a spade and replant, or cut stem cuttings in summer and let them root in lean potting soil in a shady spot.
