Perennials: for the rock garden
Once you have selected the area in your yard, it is time to step back and take into consideration the following:
1. Use rocks of one geological type
2. Consider creating a natural slope or terrace
3. Insure good soil drainage
4. Plant a variety of species, but with similar water and sun exposure needs.
5. Plan on using perennials that are low growing and have a clumping habit.
