Creeping phlox makes a pretty carpet of soft colors in spring. It’s easy to plant and take care of, so it’s perfect for gardens. You can grow it over rocks or in tough soil for a simple ground cover. It also looks nice between stones, in pots, or in a colorful spring garden.

About Creeping Phlox:

Creeping phlox is a plant that comes back every year and keeps some of its green leaves. It has pointy leaves and small star-shaped flowers in red, purple, pink, white, or light purple.

It blooms in spring and grows long, spreading stems that become hard as they get older. You can cut away the old stems to help new ones grow and bloom.

Creeping phlox grows at a medium speed and can get about 4 to 6 inches tall and spread out about 2 feet.

Creeping phlox, also called moss phlox or star rock phlox, is a plant that comes back every year. It’s not too big, growing about 6 to 12 inches tall and spreading out 9 to 18 inches wide. It likes being in the sun, but it’s okay with a bit of shade too. It needs soil that drains well, and it can handle soil that’s a little acidic or alkaline. Creeping phlox blooms in the spring and summer, showing off flowers in purple, pink, or white. It grows well in parts of the USA, in zones 5 to 9, and it’s originally from North America.

Taking care of creeping phlox

Taking care of creeping phlox is simple. You just need to water it if there’s no rain for a week or two, and feed it once a year. Sometimes, you might need to trim it a bit to keep it neat, unless you want it to spread on its own.

Weeds can be a problem because they’ll compete with your phlox for water and nutrients. It’s best to deal with them early in the spring before the phlox starts to bloom and its leaves grow fully. Pulling weeds by hand is the best way. If the weeds get out of control, it might be easiest to dig up the phlox, clear out the weeds and grass, then plant it again.
