For gardeners seeking quick coverage, popular “fast-growing ground cover” categories often include plants such as creeping thyme, creeping phlox, and ajuga—each bringing its own unique texture and seasonal color.This crowded planting causes their leaves to be wet for a long period of time after rainfall or irrigation, and this favors fungal infections.
