About Ground Covers
Ground covers are plants with innumerable crowns whose roots spread through the ground; not plants having a central crown from which annual stems cover the ground for a season. Most wide-spreading geraniums that are used as ground covers do best in light shade or areas with filtered light. For sunny locations use G. himalayense in Borders and Bedding and G. dalmaticum from Rock Gardens and Containers. Plants in this section will take half sun to filtered light. In hot summer areas they may need total shade.
