Answer: Rose bushes usually like to be the center of attention, but you could plant thyme under your shrubs without harm to either the shrubs or the groundcover. When choosing companion plants, or plants growing in close proximity to one another, always try to find plants with the same cultural requirements. If they have similar needs for sunlight, water, and fertilizer, they will have fewer problems. Some plants have invasive root systems, and that could cause undue competition for water and nutrients, but thyme is not one of those plants. All in all, thyme is a good choice for growing under roses.
