Maintenance
If Creeping Phlox is placed to close to a sidewalk, patio, etc. it will creep into this area. Most people will shear it straight on the edges leaving a rough brown edge. A way to avoid this ugly look is to lift the edges of the plant up and cut the brown underside of the plant leaving a layer of growing foliage on the top to fill in. Than take this foliage and feather it back with a pruning shear or scissors. This works with Creeping Phlox because it tends to grow in layers with the new growth creeping over the older growth. When grass or weed start growing through the foliage, lift the plant and pull the weeds from underneath. Once the Phlox is established the weed problem will be minimal. A light shearing after bloom will incourage compact growth.
Propagation
cuttings or division in the spring
Native Site
Species plant native to North America.
Cultivar Origin
First sent to England in 1745 by John Bartram, a early American botanist.
Misc Facts
The name comes from the foliage (moss like) and the blue color of the flowers
Author's Notes
I have been growing or observing this Creeping Phlox for over 30 years. Very hardy, always florific and seems to be one of the faster growing cultivars.
