Q.Am looking for very low growing green ground cover, year round zone 7B
This is for a small raised bed. Hoping to find a “growing” mulch I can add flower plants to when desired/spring bulbs can come up thru. Full sun in summer, a bit less in the winter can water when needed just outside Atlanta (east side) I am a lazy gardener who likes my flowers would like something mostly just green & pretty forgiving. Does something exist? If not, I’ll keep using mini pine bark

Sure, you have quite a few choices here! Wooly Thyme is one of my favorites, along with Herniaria, but there are more options, too. These articles will help:
